Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to electronic document processing, and more particularly to a document processing apparatus capable of displaying and outputting a text as electronic document data and an abstract created from the text.

[0002]

2. Description of the Related Art Conventionally, WWW (World Wide Web) has been provided as an application service for providing hypertext information in a window format on the Internet.

[0003] The WWW is a system for executing document processing for creating, publishing, or sharing a document, and showing the way of a new style document. However, from the viewpoint of practical use of documents, advanced document processing beyond WWW, such as classification and summarization of documents based on the contents of the documents, is required. For such advanced document processing, mechanical processing of the contents of the document is indispensable.

However, mechanical processing of the contents of a document is still difficult for the following reasons. First
HTML, a language that describes hypertext
(Hyper Text Markup Language) specifies the expression of a document, but hardly specifies the content of the document. Second, a network of hypertexts formed between documents is not always easy for a reader of the document to understand the contents of the document. Third
In general, the author of a document writes without considering the convenience of the reader, but the convenience of the reader of the document is not adjusted to the convenience of the author.

[0005] As described above, the WWW is a system showing the way of a new document. However, since the document is not mechanically processed, advanced document processing cannot be performed.
In other words, in order to perform advanced document processing, it is necessary to process the document mechanically.

Therefore, a system for supporting mechanical processing of documents has been developed based on the results of natural language research, with the goal of mechanical processing of documents. As a document processing based on natural language research, mechanical document processing using tags attached to a document has been proposed on the assumption that attribute information about the internal structure of the document by the author of the document, so-called tags are added. I have.

[0007]

By the way, with the recent spread of computers and the progress of networking, text processing, creation of text documents, labeling, change, and the like have been performed by using an index depending on the contents of the documents. There is a demand for enhanced document processing to be performed. For example, it is desired to summarize a document or classify a document according to a user's request. Also,
Processing that is more suitable for users, such as display styles suitable for the form of the document viewer or display unit that displays documents and their summaries, read-aloud functions that accompany display, and interlocking of display of documents and images with read-aloud is required. ing. In particular, when displaying a text or an abstract, it is necessary to appropriately present the document content to the user according to the status of the display area.

[0008]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above circumstances, and a document processing apparatus has been proposed to accurately document contents (summary contents) according to the state of a document display area. The purpose is to be able to display to the user.

Therefore, the document processing apparatus of the present invention determines whether the electronic document data is fixedly displayed according to the aspect ratio discrimination means for discriminating the aspect ratio of the document display area and the aspect ratio discriminated by the aspect ratio discrimination means. And a display control unit for setting whether to perform switching display or moving display for each part (for example, telop display) and executing display in the document display area. In other words, for example, when the document display area is extremely long when it is assumed that the document is a horizontally written document, the document is displayed in the form of a telop and displayed by switching or moving to realize a document presentation that is easy for the user to see (read). I do.

The aspect ratio of the document display area can be arbitrarily changed by providing an aspect ratio variable means capable of changing the aspect ratio of the document display area. And whether to move or switch display.

In particular, there is provided a summary creating means for creating electronic document data as a summary sentence from electronic document data as a document body.
The display control means determines the aspect ratio of the summary sentence display area in which the summary sentence is displayed, and, depending on the determined aspect ratio, either fixedly displays the electronic document data as the summary sentence, or switches display of each part. Alternatively, it is set whether or not to perform the moving display, and the display in the summary display area is executed. That is, the above-described display is realized as a display mode of the summary sentence. In addition, the summary creating means creates a summary sentence having a document length corresponding to a document length that can be displayed in the summary sentence display area, according to an aspect ratio of the summary sentence display area determined by the aspect ratio determining means, The user selects whether to create a summary sentence having a document length exceeding the document length that can be displayed in the summary sentence display area, and creates a summary sentence. That is, in the case of moving or switching display, a longer summary is created.

According to the document processing method of the present invention, an aspect ratio determining step of determining an aspect ratio of a document display area on a display unit;
A display control procedure for setting whether to display the electronic document data in a fixed manner or to perform switching display or moving display for each part according to the aspect ratio determined by the aspect ratio determination procedure, and to execute display in the document display area. And so on. Further, an aspect ratio changing procedure for changing the aspect ratio of the document display area is further provided. In addition, the system further includes a summary creation step of creating electronic document data as an abstract from the electronic document data as the document body, and the aspect ratio determining step includes determining an aspect ratio of an abstract display area in which the abstract is displayed. In the display control procedure,
According to the aspect ratio determined by the aspect ratio determination procedure, whether to display the electronic document data as the summary sentence fixedly, or to switch or move the display for each part is set, and the display in the summary sentence display area is executed. Let it do. Also, in the summary creation procedure, in accordance with the aspect ratio of the summary sentence display area determined by the aspect ratio determination procedure, whether to create a summary sentence having a document length corresponding to the document length that can be displayed in the summary sentence display area, The user selects whether to create a summary sentence having a document length exceeding the document length that can be displayed in the summary sentence display area, and creates a summary sentence. The recording medium of the present invention is assumed to record an operation control program having the above-described procedures. Further, the electronic document data to be processed by the operation control program is recorded together with the operation control program.

1. 1. Configuration of Document Processing Apparatus As shown in FIG. 1, a document processing apparatus 1 according to an embodiment of the present invention includes a main body 10 having a control unit 11 and an interface 12, and a main body 10 which receives an input from a user.
, An input unit 20 for sending and receiving signals to and from the outside, and a display unit 30 for displaying an output from the main body 10
Recording / reproduction for recording / reproducing information on / from the recording medium 32
It has a reproduction unit 31, an audio output unit 33, and an HDD (hard disk drive).

The main body 10 has a control unit 11 and an interface 12, and constitutes a main part of the document processing apparatus 1. The control unit 11 has a CPU 13 that executes processing in the document processing apparatus 1, a RAM 14 that is a volatile memory, and a ROM 15 that is a non-volatile memory. The CPU 13 temporarily stores data, if necessary, in the RAM 14 according to a procedure recorded in the ROM 15, for example, and performs control for executing the program. The operation of the control unit 11 is as follows.
As will be described later in detail, there are a classification process for the supplied document data, a summary creation process, a process of generating a speech reading file for a reading operation, and a document analysis required for these processes. The programs and application software necessary for these operations are stored in the ROM 15, the HDD 34, or the recording medium 32.
Is stored in The document processing program used by the control unit 11 may be stored in the ROM 15 in advance as described above, or may be fetched from the recording medium 32 or the HDD 34. It is also conceivable to download a document processing program provided by an external server or the like.

The interface 12 includes a control unit 11, an input unit 20, a communication unit 21, a display unit 30, and a recording / reproducing unit 3.
1. Connected to the audio output unit 33 and HDD. Under the control of the control unit 11, the interface 12 inputs data from the input unit 20, inputs and outputs data to and from the communication unit 21, outputs data to the display unit 30, and controls the recording / reproducing unit 31. Each operation of data input / output, data output to the audio output unit 33, and data input / output to the HDD 34 is performed. More specifically, it adjusts the timing of data input / output between the control unit 11 and each of the above units, converts the format of data, and the like.

The input section 20 is a section for receiving an input from the user to the document processing apparatus 1. This input unit 20
Is composed of, for example, a keyboard and a mouse. The user uses the input unit 20 to input characters such as keywords using a keyboard, or to display the display unit 30 using a mouse.
For example, the user can select an element of the electronic document that is displayed in. Hereinafter, an electronic document handled by the document processing apparatus 1 is referred to as “document data” or simply “document”. The “element” is an element constituting a document, and includes, for example, a document, a sentence, and a word.

The communication unit 21 is a unit that receives a signal transmitted from the outside to the document processing apparatus 1 via, for example, a communication line, and transmits a signal to the communication line. The communication unit 21 receives one or a plurality of data such as documents transmitted from the outside, and sends the received data to the main body 10. Of course, data is transmitted to an external device via a communication line.

The display section 30 is a section for displaying characters and image information as an output of the document processing apparatus 1. The display unit 30 is, for example, a cathode ray tube (CR).
T), a liquid crystal display (LCD), or the like, for example, displays one or more windows, and displays characters, figures, and the like on these windows.

The recording / reproducing section 31 records / reproduces data on / from a recording medium 32 such as a so-called floppy (registered trademark) disk. Here, a floppy disk (magnetic disk) is taken as an example of the recording medium 32. However, any portable medium such as an optical disk, a magneto-optical disk, and a memory card can be applied as an example of the recording medium 32. The recording / reproducing unit 31 may be any recording / reproducing device (disk drive, card drive, etc.) corresponding to the medium.

When the recording medium 32 has recorded therein a document processing program for processing a document,
The recording / reproducing unit 31 can read out the document processing program from the recording medium 32 and supply it to the control unit 11. If document data is recorded on the recording medium 32, the recording / reproducing unit 31 can read it out and supply it to the control unit 11. That is, for the document processing apparatus 1,
This is an input mode of the document data different from the reception of the document data by the communication unit 21. Further, the control unit 11 can cause the recording / reproducing unit 31 to record the document data processed by the document processing apparatus 1 on the recording medium 32.

The voice output section 33 is a section for outputting a document as an output of the document processing apparatus 1 as a reading voice. That is, when a voice signal generated by a voice synthesis process based on document information (a reading file to be described later) is supplied by the control unit 11, the voice output unit 33 performs output processing of the voice signal to perform display. Together with the unit 30, it functions as an output unit of the document processing apparatus 1.

The HDD 34 provides a large-capacity recording area in the document processing apparatus 1. The HDD 34 includes the control unit 11
The recording / reproduction of information is performed based on the control of. This HDD
Reference numeral 34 denotes an application program for various processes executed by the control unit 11, for example, a program for speech synthesis, and the like, and stores, for example, document data and the like taken into the document processing apparatus 1. It can be used as a part to be kept.

2. Document Data Structure Next, the structure of document data in this example will be described. In this example, document processing is performed with reference to a tag that is attribute information assigned to the document. The tags used in this example include syntactic
c) There are tags and semantic / pragmatic tags that enable mechanical understanding of the content of documents between multiple languages.

Some syntactic tags describe the internal structure of a document. As shown in FIG. 2, the internal structure by tagging is configured such that each element such as a document, a sentence, and a vocabulary element is linked to each other by a normal link and a reference / referenced link. In the figure, a white circle “○” indicates an element, and the lowest white circle is a vocabulary element corresponding to the minimum level word in the document. The solid line is a normal link indicating a connection between elements such as a document, a sentence, and a vocabulary element, and the dashed line is a reference link indicating a dependency relationship by reference / reference. The internal structure of a document is document (documemt), subdivision (subdivision), paragraph (paragraph), sentence (sentenc
e), subsentential segment (subsentential s
egment), ..., vocabulary elements. Of these, subdivisions and paragraphs are optional.

On the other hand, as a semantic / pragmatic tagging, there is a method of describing information such as a meaning like a meaning of a polysemy. Tagging in this example is performed by HTML (Hyper Te
XML (Extensible Mar) similar to xt Markup Language
kup Language).

An example of tagging is shown below, but tagging a document is not limited to this method. In the following, examples of English and Japanese documents are shown, but the description of the internal structure by tagging can be similarly applied to other languages.

For example, “Time flies like an arro
The sentence "w." can be tagged as follows. <> is a tag added to the document.

<Sentence> <noun phrase meaning = “time0”> time </ noun phrase> <verb phrase> <verb meaning = “fly1”> flies <// verb> <adverb phrase> <adverb meaning = like0> like < / Adverb> <noun phrase> an <noun meaning = “arrow0”> arrow </ noun> </ noun phrase> </ adverb phrase> </ verb phrase>. </ Sentence>

Here, <sentence>, <noun>, <noun phrase>, <
Verbs, <verb phrases>, <adverbs>, <adverb phrases> are sentences, nouns, noun phrases, verbs, verb phrases, adjectives / adverbs (including prepositional or postpositional phrases), adjective phrases / adverbial phrases, respectively. Is shown. In other words, the syntactic structur of a sentence
e).

These tags are arranged immediately before the front end of the element and immediately after the end of the element. The tag placed immediately after the end of the element indicates that it is the end of the element by the symbol "/". Elements are syntactic constructs: phrases, clauses, and sentences. Note that the meaning (word sense) = “time0” corresponds to the word “ti”.
It refers to the plural meanings of “me”, that is, the 0th meaning of the plural meanings.
Has at least the meanings of a noun, adjective, and verb. Here, it indicates that the word "time" is a noun (= the 0th meaning). Similarly, the word "orange" has at least the meaning of plant name, color, and fruit, but these can also be distinguished by their meaning.

In this example, the syntactic structure of the document data can be displayed in the window 101 on the display unit 30, as shown in FIG. In this window 101, vocabulary elements are displayed on the right half 103, and the internal structure of the sentence is displayed on the left half 102.

For example, as shown in FIG.
1 has a sentence “A” in which the internal structure is described by tagging.
In C City, where his B meeting was over, some popular and general newspapers have stated on paper that they will voluntarily regulate their photographic coverage. Is displayed. An example of tagging this document is as follows:

<Document> <Sentence> <Adverb Phrase Relation = “Place”> <Noun Phrase> <Adverb Phrase Location = “C City”> <Adverb Phrase Relation = “Subject”> <Noun Phrase Identifier = “B Association” > <Adverb phrase relation = “affiliation”> <person name identifier = “Mr. A”> Mr. A </ personal name> </ adverb phrase> <organization name identifier = “B association”> B association </ organization name> / The noun phrase ends with </ adverb phrase> </ adverb phrase> <place name identifier = "C city"> C city </ place name> </ noun phrase>, </ adverb phrase> <adverb phrase relation = subject "> <Noun phrase identifier =“ press ”syntactic =“ parallel ”> <noun phrase> <adverb phrase> Some </ adverb phrase> popular paper </ noun phrase> and <noun> general paper </ noun> < / Noun phrase> is </ Adverb phrase> <Adverb phrase> Relation = “object”> <Adverb phrase> Relation = “content” Subject = “press”> <Adverb phrase> Relation = “Object”> <Noun phrase> <Adverb Phrase> <noun Co-reference = "B-kai"> </ noun> </ adverb phrase> Photo coverage </ noun phrase> </ adverb phrase> Self-regulating </ adverb phrase> Policy </ adverb phrase> <adverb phrase> Coordinator = "position"> </ adverb phrase> on paper. </ Text> </ text>

By being tagged in this manner, the structure of the document is expressed by each pair of tags <> to </>. For example, <document> to </ document> indicates the range of one document, and similarly, <sentence> to </ sentence> indicates the range of one sentence. Also, for example, <Noun phrase identifier = “B meeting”>
According to </ noun phrase>, the part "Mr. A's B meeting"
It is expressed as a noun phrase with "kai" as the identifier. That is, the internal structure of the sentence shown on the left half surface 102 in FIG. 3 is expressed by the tagging.

Further, in this document, "part of popular paper and general paper" is expressed in parallel by a tag of syntactic = "parallel". The definition of parallel is to share a dependency relationship. If nothing is specified, for example, <noun phrase relation = x><noun> A </ noun><noun> B </ noun></ noun phrase> indicates that A has a dependency on B Represent. Relation = x represents a relation attribute.

The relation attribute describes an interaction between syntactic, meaning, and rhetorical. Grammar functions such as subjects, objects, and indirect objects, subject roles such as an actor, a subject, a beneficiary, etc., and rhetorical relations such as a reason and a result are described by the relation attributes. In this example, the subject, object,
Describe relative attributes for relatively easy grammar functions such as indirect objects.

In this document, "Mr. A",
For proper nouns such as "B Association" and "C City", place names,
Attributes are described by tags such as person names and organization names. By adding tags such as place name, person name, organization name, etc.,
It is expressed that the word is a proper noun.

3. Manual Classification Processing on Document Data 3-1 Processing Procedure In the document processing apparatus 1 of this example, when document data is taken in from the outside by, for example, the communication unit 21 (or the recording / reproducing unit 31), the document data is converted according to the content. Perform classification processing. In the following description, it is described that document data from the outside is taken in via the communication unit 21.
The description is the same when the document data is supplied from the outside in the form of a portable medium such as a floppy disk and the document data is taken in from the recording / reproducing unit 31.

As the classification process, there are a manual classification process in which the user manually classifies according to the contents of the document data, and an automatic classification process in which the document processing apparatus 1 automatically classifies. These classification processes are performed based on a classification model described later. However, in the document processing apparatus 1, no classification model exists in an initial state. Therefore, at the time of the initial state, a classification process including creation of a classification model is required as a manual classification process. After the classification model is generated, the input document data can be automatically classified. First, a manual classification process that needs to be performed first will be described. That is, the manual classification process means that when the document processing apparatus 1 in the initial state receives document data sent from the outside, the control unit 11 creates a classification model and classifies the document data based on a user operation. Is performed.

FIG. 4 shows the entire processing procedure as the manual classification processing. The detailed processing of each processing step will be described later.

Step F11 in FIG.
2 shows a document receiving process by the receiving unit 21 of FIG. In step F11, the receiving unit 21 receives one or a plurality of documents transmitted via, for example, a communication line. The receiving unit 21 sends the received document to the main body 10 of the document processing device. The control unit 11 stores the supplied document data or document data in the RAM 14 or the HDD 34.

In step F12, the control section 11 of the document processing apparatus 1 extracts the features of the plurality of documents sent from the receiving section 21 and creates feature information, that is, an index of each document. The control unit 11 stores the created index in, for example, the RAM 14 or the HDD 34.
As will be described later, the index includes proper nouns, meanings other than proper nouns, and the like, which are characteristic of the document, and can be used for document classification and search.

The document browsing in step F13 is a process executed as required by the user. That is, it is performed according to a user operation. Step F13 and the next step F14 are processes based on a user operation.
The user can view the content of the input document data on the screen of the display unit 30 by performing a required operation. While browsing the document, the user can instruct various processes such as summarization, which will be described later, by operating the icons and the like on the screen. The process will proceed to the classification operation. In step F14, in response to the user performing an operation of setting a classification item (the classification item is also referred to as a category in this specification), the control unit 11
Generates / displays classification items. The user also performs an operation of sorting the document data into the set classification items, and the control unit 11 sorts and displays the document data accordingly.

In step F15, the control unit 11 creates a classification model in accordance with the classification item creation and classification operation performed by the user in step F14. The classification model includes a plurality of classification items (categories) for classifying documents, and associates each document index with each category index (index of each document created in step F12) to change the classification state. This is the specified data.
After generating such a classification model, step F16
Then, the classification model is registered. That is, the control unit 11 performs the registration by storing the classification model in, for example, the RAM 14. By the processing of FIG. 4 described above, manual classification and creation of a classification model have been performed for one or a plurality of pieces of document data input when the document processing state 1 is in the initial state. The processing of step F12 and subsequent steps in FIG. 4 will be described in detail.

3-2. Index Creation In step F14, the control unit 11 creates an index for the input document data. First, a specific example of an index created for certain document data will be described.

<Index Date = "AAAA / BB / CC" Time = "DD: EE: FF" Document Address = "1234"> <User Operation History Maximum Summary Size = "100"> <Number of Selected Elements = " 10 ”> Picturetel </ selection> ・ ・ ・ </ user operation history> <summary> Tax reduction scale, not touching-Prime Minister X's interview </ summary> <word meaning =“ 0003 ”central activity value =“ 140.6 ” > Do not touch </ word> <word meaning = “0105” identifier = “X” central activity value = “67.2”> Prime Minister </ word> <person name identifier = “X” word meaning = “6103” central activity value = “ 150.2 ”> X Prime Minister </ word / person name> <word meaning =“ 5301 ”central activity value =“ 120.6 ”> found </ word> <word word meaning =“ 2350 ”identifier =“ X ”central activity value =“ 31.4 ”> Prime Minister </ word> <word meaning =“ 9582 ”Central activity value =“ 182.3 ”> Emphasis </ word> <word meaning =“ 2595 ”Central activity value “93.6”> Touch </ word> <word Teijin = “9472” Central activity value = “12.0”> Notified </ word> <word Sense = “4934” Central activity value = “46.7”> No touch < / Word> <word meaning = “0178” central activity value = “175.7”> declared </ word> <word meaning = “7248” identifier = “X” central activity value = “130.6”> I </ word> < Word Meaning = "3684" Identifier = "X" Central Activity Value = "121.9"> Prime Minister </ word> <Word Meaning = "1824" Central Activity Value = "144.4."> Complained </ word> <word Meaning = “7289” Central activity value = “176.8”> Showed </ word> </ index>

In this index, <index> and </ index> indicate the start and end of the index, <date> and <time> indicate the date and time when this index was created, <summary> and </ Summary> indicates the start and end of the summary of the contents of this index, respectively. Also, <word> and <
/ Word> indicates the beginning and end of the word. Further, for example, the meaning = “0003” indicates that it is the third meaning. The same applies to other cases. As mentioned above,
Since the same word may have a plurality of meanings, a number is predetermined for each meaning in order to distinguish them, and the corresponding meaning is represented by a number.

<User operation history> and </ User operation history> are the start and end of the user's operation history, and <Select> and </ Select> are the start and end of the translated element. Are respectively shown. The maximum summary size = “100” indicates that the maximum size of the summary is 100 characters, and the number of elements = “10” indicates that the number of selected elements is 10.

As in this example, the index includes proper nouns, meanings other than proper nouns, and the like, which are characteristic of the document. For example, the process of step F12 for creating such an index will be described with reference to FIGS. FIG. 5 shows an index creation process for one document data. Therefore, when a process is performed for a plurality of document data, the process of FIG. 5 is performed for each document data. Further, FIG. 7 shows a detailed process of step F31 in FIG. 5, and FIG. 8 shows a detailed process of step F43 in FIG.

As the index creation processing in step F12 in FIG. 4 described above, first, active diffusion in step F31 in FIG. 5 is performed. This active diffusion is a process in which the central activity value of an element is spread based on the internal structure of a document with respect to document data, so that an element related to an element having a high central activity value also has a high central activity value. It is. That is, after giving a central activity value as an initial value to each element constituting the document, the central activity value is diffused based on the internal structure of the document, specifically, the link structure. Since this central activity value is determined according to the internal structure by tagging, it is used for extracting features of a document. The control unit 11 determines in step F3
As 1, the active diffusion is performed, and the central active value of each element obtained as a result of the active diffusion is stored in, for example, the RAM 14.
Will be stored.

FIG. 6 shows the active diffusion in step F31.
8 will be described in detail. First, an example of a link structure between elements is shown in FIG. In FIG.
The periphery of elements E1 and E2 is shown as part of the structure of the elements and links that make up the document. E1
E8 is an example of an element, in which element E
1 and E2 will be described.

It is assumed that the central activity value of element E1 is e1, and the central activity value of element E2 is e2. The elements E1 and E2 are connected by a link L12 (the normal link or the reference link described above). The end point of the link L12 connected to the element E1 is T12, and the end point of the link L12 connected to the element E2 is T21. Element E1 further includes elements E3, E4,
E5 is connected to links L13, L14, and L15, respectively. The end points of the links L13, L14, and L15 on the element E1 side are denoted by T13, T14, and T, respectively.
It is assumed to be 15. Element E2 is composed of elements E6 and E6.
Links L26, L27, L2 for E7 and E8 respectively
8 are connected. Each link L26, L27, L28
At the element E2 side are denoted by T26 and T26, respectively.
27 and T28. The active diffusion processing of FIGS. 7 and 8 will be described using an example of such a link structure.

In step F41 of FIG. 7, when starting the active diffusion for the document data to be indexed, the control unit 11 first initializes the central active value for all elements of the document data. As the initial value of the central activity value, for example, a high value is given to a proper noun, an element selected (clicked) by a user, or the like. Further, the control unit 11 sets the end point activation value of the end point T (xx) of the link connecting the elements to 0 for the reference link and the normal link. The control unit 11 stores, for example, the RAM 14 with the initial value of the endpoint activation value thus assigned.

In step F42, the controller 11
Initializes a counter for counting the elements Ei constituting the document. That is, the count value i of the counter for counting elements is set to one. If i = 1, this counter will refer to the first element (eg, element E1 in FIG. 6).

In step F43, the control unit 11
Executes a central activation value update process for calculating a new central activation value for the element referenced by the counter. This center activation value update process will be described in detail with reference to FIG. 8 by taking the process for the element E1 as an example. The center activation value updating process is a process of updating the end point activation value of the element, and calculating a new center activation value using the updated end point activation value and the current center activation value.

In step F51 of FIG.
Is an element Ei (for example, in this case E
In 1), a counter for counting the number of links having one end connected thereto is initialized. That is, the count value j of the counter for counting the links is set to one. When j = 1, this counter refers to the first link L (yy) connected to the element Ei. In the example of FIG.
For example, the link L12 is referred to as the first link for the element E1.

In step F52, the control section 11 determines whether or not the link being referred to, that is, the link L12 connecting the elements E1 and E2, is a normal link by referring to the tag of the related attribute. If the link L12 is a normal link, the control unit 11 proceeds to step F53, and if the link L12 is a reference link, proceeds to step F54.

If the link L12 is determined to be a normal link and the process proceeds to step F53, the control section 11 performs a process of calculating a new endpoint activation value of the endpoint T12 connected to the normal link L12 of the element E1. Endpoint T12
Are the endpoint activation values of all the endpoints connected to the link other than the link L12 among the endpoint activation values of the linked element E2 (in this case, T26 and T2).
7, each end point activation value t26, t27, t28 of T28)
And the central activation value e2 of the element E2, and the value obtained by this addition is divided by the total number of elements included in the document. The control unit 11 performs such an operation using each endpoint activity value and each center activity value read from the RAM 14, thereby calculating a new endpoint activity value for the endpoint connected to the normal link. The calculated end point activation value is stored in the RAM 14. That is, the end point T1
The end point activation value t12 of No. 2 is updated.

On the other hand, if it is determined in step F52 that the link L12 is a reference link and the process proceeds to step F54, the control unit 11 similarly sets a new endpoint activation of the endpoint T12 of the element E1 connected to the normal link L12. The processing for calculating the value is performed. The calculation for calculating the end point activity value is as follows. That is, in this case, the endpoint activation values t12 of the endpoint T12 are the endpoint activation values of all the endpoints connected to the link other than the link L12 among the endpoint activation values of the linked element E2 (in this case, T2
6, each end point activation value t26, t27, t of T27, T28
28) and the central activation value e2 of the element E2. (That is, the point where there is no division is different from the case of the above-mentioned normal link.) Then, the control unit 11 performs such an operation using each of the endpoint activation values and each of the center activation values read from the RAM 14, A new endpoint activity value is calculated for the endpoint connected to the reference link, and the calculated endpoint activity value is stored in the RAM. That is, the end point activation value t12 of the end point T12 is updated.

After performing the processing in step F53 or F54, the control unit 11 performs the processing in step F5 through the determination processing in step F55 (if the determination result is NO).
Proceeding to 7, the count value j is incremented, and the process returns to step F52. That is, subsequently, by setting the count value j = 2, the second link (for example, link L13) for the element E1 is referred to.
In the same manner as described above, the end point activation value t13 of the end point T13 connected to the link L13 is calculated / updated in the processing after step F52.

In step F55, the control unit 11 determines whether or not new end point activation values for all links have been calculated for the element Ei (E1) currently being referred to by the count value i, and branches the processing. Because
The process of updating the endpoint activation values is performed until all endpoint activation values of the element Ei being referred to are updated. That is, by repeating the process while incrementing the count value j in step F57, for the element E1, for example, the endpoint activation values t12, t13, t14, and t15 are updated for the endpoints T12, T13, T14, and T15, respectively. When all of them have been updated, the process proceeds from step F55 to F56.

In step F56, a new central activity value ei of the element Ei is calculated by using the updated endpoint activity values in response to all the endpoint activity values for the element Ei being obtained. The new central activation value ei of the element Ei is the current central activation value e of the element Ei.
It is determined by the sum of new endpoint activation values of all endpoints of i and element Ei. For example, in the case of the element E1 in FIG. 6, the new central activation value e1 (new) is e1 (new) = e1 + t12 + t13 + t14 + t15.

The control unit 11 calculates the central activation value ei of the element Ei being referred to by the current count value i in this way. Then, the control unit 11 causes the RAM 14 to store the calculated new central activation value ei. That is, the central activation value ei of the element Ei is updated. (However, at this point, the old center activation value is also held because it is used in the process of step F45 described later.)

When the processing shown in FIG. 8 is performed as the central activation value updating processing in step F43 in FIG. 7, the processing of the control unit 11 proceeds to step F44 in FIG.
The control unit 11 determines whether or not the central activation value update processing has been completed for all elements in the document. Specifically, control unit 11 determines whether or not count value i has reached the total number of elements included in the document. Control unit 1
When the central activation value update processing has not been completed for all the elements, the process proceeds to step F47, where the count value i is incremented, and
Return to For example, after the processing for the element E1 is completed as described above, the count value i is set to 2 and the element E2 is referred to this time. Then, for the element E2, the central activation value update processing of step F43 (that is, the processing of FIG. 8) is performed in the same manner as described above. Although the details will not be described because they are redundant description, in the case of the link example of FIG. 6, in the case of the element E2, the end point activation values t21, t26, t27 of the end points T21, T26, T27, T28 in the processing of FIG. After t28 is updated,
A new central activity value e2 (new) is calculated as e2 (new) = e2 + t21 + t26 + t27 + t28, and is updated.

In the processing shown in FIG. 7, the count value i is incremented in step F47 and the central activation value update processing in step F43 is repeated while the reference element is changed. Will be updated.

When the update of the central activation value has been completed for all the elements in the document, the processing is terminated at step F44.
To F45. In step F45, the control unit 11 calculates the average value of the change in the central activity values of all the elements included in the document, that is, the change in the newly calculated central activity value from the original central activity value. For example, the control unit 11 reads the old central activation value stored in the RAM 14 and the updated new central activation value for all elements included in the document. Then, for each element, the difference between the new central activity value and the old central activity value is obtained, and the sum of the differences is divided by the total number of elements to calculate the average value of the change in the central activity value of all elements. The control unit 11 causes the RAM 14 to store, for example, the average value of the change in the central activity value of all elements calculated in this way.

Subsequently, at step F46, the control unit 11
Determines whether the average calculated in step F45 is within a preset threshold. When the average value is within the threshold value, the control unit 11 ends a series of steps as the active diffusion process. When the average value is not within the threshold value, the control unit 11 returns to step F42 and performs the above-described series of processes. Perform the process again.

This series of active diffusion processing can be said to be processing for raising the central activity value of an element related (linked) to an element having a high central activity value. However, by performing this activation diffusion only once, when considering the purpose of the index creation processing, among the elements that should be able to raise the central activation value,
In some cases, the central activity value may not be sufficiently raised. For example, in one activation diffusion, for an element directly linked to an element for which the initial value of the central activation value is set high, the central activation value is raised to some extent, but for an element that is not directly linked, it is Even if the element is important as an index, the central activity value may not be sufficiently raised. Therefore, by performing the active diffusion process a plurality of times as necessary based on the determination in step F46, the central activity value can be converged as a whole, and important elements that cannot be increased in the central activity value As much as possible. The reason why the central activity value is converged as a whole in the active diffusion process a plurality of times is that the central active value of each element updated in the active diffusion process is based on the central activity value of each element, and further the active activity diffusion process is performed for each element. This is because the central activity value is updated. However, if such activation diffusion processing is performed too many times, the central activation values of all the elements converge and become almost the same, which is inappropriate.
For this reason, in the processing of steps F45 and F46, the end timing of the active diffusion process is determined based on the change so as to obtain the average value of the change of the central active value, so that the active diffusion suitable for index creation is performed. Will be realized.

When the active diffusion processing as shown in FIGS. 7 and 8 (ie, step F31 in FIG. 5) is completed, the controller 1
The process 1 proceeds to step F32 in FIG. In step F32, the control unit 11 determines in step F3
Based on the central activity value of each element obtained in step 1, an element whose central activity value exceeds a preset threshold is extracted. The control unit 11 causes the RAM 14 to store the extracted elements.

Subsequently, in step F33, the control section 11 reads out the elements extracted in step F32, for example, from the RAM 14. Then, the control unit 11 extracts all proper nouns from the extracted elements and adds them to the index. Proper nouns have special properties such as having no meaning and not appearing in dictionaries, and are therefore treated separately from words other than proper nouns. As described above, the word meaning corresponds to each of a plurality of meanings of the word. Whether or not each element is a proper noun can be determined based on a tag attached to the document. For example, in the internal structure by tagging shown in FIG. 3, "A", "B" and "C"
“City” is a proper noun since the related attributes of the tags are “person name”, “organization name”, and “place name”, and the control unit 11 adds the extracted proper noun to the index, and The result is stored in the RAM 14.

In the next step F34, the control unit 1
1 extracts the meanings other than proper nouns from the elements extracted in step F32, adds them to the index, and stores the result in the RAM 14.

By the above processing, for example, an index as in the above specific example is generated. That is, the index finds the features of the tagged document and arranges the features, and the features of the document are determined based on the central activity value diffused according to the internal structure of the document. It will be. Since such an index includes meanings and proper nouns representing features representative of a document, it can be used when referring to a desired document. The index includes, in addition to the meanings and proper nouns representing the characteristics of the document, the document in the RAM 14 (or H
The document address indicating the position stored in DD34) is included.

3-3 Document Browsing / Category Creation / Classification Operation The index creation processing described above with reference to FIGS. 5 to 8 is performed in step F12 in FIG. Therefore, FIG.
As for the manual classification processing of step F13 and step F1
The process proceeds to the process of No. 4, that is, the process of browsing and manual classification by the user as described above.

As described above, in step F13 of FIG. 4, the user can browse the document displayed on the display unit 30. In step F14, the user can perform an operation of setting a classification item and an operation of sorting document data into the set classification item. The operations performed in steps F13 and F14,
The corresponding process of the control unit 11 and a display example of the display unit 30 are as follows.

FIGS. 9 and 10 show specific examples of the display on the display unit 30. FIG. First, FIG. 9 is a display example of a document classification window 201 corresponding to a classification model described later in detail. That is, a graphic user interface (graphic user interface) used for displaying a document classification.
GUI). This document classification window 201
The operation button display 202 includes a position reset button 202a for returning a screen window state to an initial position, a browser button 202b for calling a browser (browser) for reading the contents of a document, An exit button 202c is displayed.

The document classification window 301
Document classification areas 203, 204, 205,... Are formed as small windows corresponding to the classification items corresponding to the classification model. The document classification area 203 is an area for displaying “other topics”. The “other topics” document classification area 203 is an area where documents that have not been classified yet are presented. For example, step F in FIG.
Each document received at 11 (that is, a document to be classified) is presented in the "other topics" document classification area 203. The document classification area 204 is an area where documents classified as, for example, “business news” are presented. The document classification area 205 is an area in which documents classified as, for example, “political news” are presented. In addition to these, document classification areas without reference numerals in the figure are areas where documents corresponding to specific classification items are presented.

Each of these document classification areas 203 and 204
.., The documents classified into the classification items (categories) set in the respective document classification areas are presented by the icon of the document and the title of the document. If there is no title, a summary of one sentence is displayed. Also, the size of each of the document classification areas 203, 204,... Is not fixed,
When the user moves the delimiting frames 211, 212, 213,... Separating the document classification areas by a drag operation or the like, the document classification areas 203, 204,.
Can be arbitrarily changed. The user can arbitrarily increase or decrease the number of document classification areas.

Each of the document classification areas 203, 204,.
The title (for example, "political news") can be arbitrarily set and changed by the user. Note that the number of document classification areas and each title correspond to the classification items of the classification model described later. In other words, the user sets or deletes a document classification area or performs a title setting in the classification window 201 by operating the input unit 20 using a mouse, a keyboard, or the like.
The number and title of the classification items of the classification model are set.

FIG. 10 shows an example of a browsing window 301 for a user to browse the contents of document data. For example, the user clicks on a certain document in the classification window 201 of FIG. 9 to select the document, and then clicks the browser button 202b, so that the control unit 11
Opens a browsing window 301 for displaying the selected document as shown in FIG.

In the browsing window 301, a file name display unit 3 for displaying the file name of the document data file
02, a document display unit 303 for displaying the document data of the file name, a summary display unit 304 for displaying a summary of the document displayed on the document display unit 303, and a keyword display unit 305 for inputting / displaying a keyword. . As the operation button display 306, a summary creation button 306a for instructing creation of a summary sentence, an undo button 306b for performing an undo operation (operation cancellation), a reading button 306c for executing a reading operation, and the like are displayed. Is done.

In such a browsing window 301,
The user can browse the document displayed on the document display unit 303. If the entire document cannot be displayed, a part of the document is displayed. Of course, you can browse the full text by scrolling. In addition, by clicking the summary creation button 306a, the user can cause a summary sentence for the document displayed on the document display unit 303 to be created and displayed on the summary display unit 304. The process of the control unit 11 for creating the summary sentence will be described later. Further, by clicking the read-aloud button 306c, the user can cause the text or the summary of the document displayed on the document display section 303 to be read aloud. This reading operation will also be described later.

The classification window 201 and the browsing window 301 as described above are displayed on the display unit 20 at any time according to the user's operation, not limited to the manual classification processing in FIG. As for the manual classification process,
The user can confirm the type and content of the received document in the classification window 201 and the browsing window 301. Specifically, one or a plurality of documents received in step F11 in FIG. 4 are subjected to the index creation processing in step F12, and then the classification window 2 shown in FIG.
01 "other topics" document classification area 20
3 is displayed. In this classification window 201,
The user manually classifies each of the documents displayed in the document classification area 203. If, for example, the content is not known only by the title of the document, the user checks the content of the document by using the browsing window 301 in FIG. . The browsing performed as needed by the user in this manner is the process of step F13 in FIG.

In step F14, the user can arbitrarily add, update, or delete a classification item on the classification window 201, and in accordance with the operation, the control unit 11 causes the displayed document classification area 203, 204 ...
・ Change the display mode (number, area, title, etc.). The setting / change of the classification item (title of the document classification area) by the user is reflected in the classification model described later.

After setting the classification items as necessary, the user sorts each document displayed in the document classification area 203 into each document classification area. That is, the documents are classified manually by the user. Specifically, the icon of the document displayed in the document classification area 203 of “other topics” is dragged to the document classification area corresponding to a desired classification item (category) using, for example, the mouse of the input unit 20. Do it by doing. For example, the user sets a document classification area titled “Sports”, and changes the icon of a sports-related document displayed in the document classification area 203 of “Other topics” to the document classification area of “Sports”. Perform an operation like dragging. The icons and titles of the documents that have been manually classified in this manner are thereafter displayed in the dragged destination document classification area.

3-4 Creation / Registration of Classification Model As described above, when the user performs the manual classification operation, the control unit 11 determines in step F15 of FIG. 4 that the classification model is composed of a plurality of categories based on the user's classification operation. Create That is, the control unit 11 collects indices of the plurality of documents classified into each category and generates a classification model. Then, the plurality of documents are classified into each category of the classification model.

The classification model is composed of a plurality of classification items (categories) for classifying documents. Then, for each category, a data format is provided in which the classified documents are shown.
An index is formed for each document in step F12 and the like, and the classification model is, for example, as shown in FIG.
As shown in (1), the data structure is such that the indexes of the documents classified for each category are associated with each other.
In FIG. 11A, the category is “sports”.
“Company”, “Computer”, etc. are set, but these are the classification items set by the user in the classification window 201 as described above. Of course, even if the user does not set, it is set in advance (that is, displayed as a document classification area in the classification window).
There may be categories. Each of the classification items is associated with an index IDX1, IDX2,.
That is, the index of the document classified by the user as described above is associated with each classification item.

The index associated with each classification item is the index of the document displayed in the document classification area of the classification item in the classification window 201. For example, the index IDX1 is associated with the category "sports" because the user creates a document classification area with the title "sports" in the classification window 201, and furthermore, sets the icon of the document of the index IDX1 to "sports". Is manually dragged to a document classification area having a title of "".

As described above, the index of each document includes proper nouns, meanings other than proper nouns, document addresses, and the like. Then, for example, as shown in FIG.
One or a plurality of indices are associated with one classification item. Since the indexes include proper nouns, meanings, document addresses, and the like, the classification model can be represented as shown in FIG. 11B.

That is, as shown in FIG. 11B, the classification model has a structure having columns of proper nouns, meanings other than proper nouns, and document addresses as category indexes corresponding to each category. Then, in the classification model, the proper noun “Mr. A” for each category “sports” “society” “computer” “plant” “art” “event”
... "," Mr. B, ... "," Company C, Company G, ...
"," D type, ... "," Mr. E, ... "and" F
A proper noun such as "Mr." is also assigned.
546), ground (2343), ... "," labor (3112), unique (9821), ... "," mobile (2102), ... "," cherry blossom 1 (11111), orange 1 ( 9911) "," Sakura 2 (11112), Orange 2 (9912) ", and" Sakura 3 (11113) "are also assigned to each category. Further, the document addresses" SP1, SP2, SP3,... " “S01,
S02, S03,... "," CO1, CO2, CO
3, ... "," PL1, PL2, PL3, ... ",
"AR1, AR2, AR3, ..." and "EV1,
EV2, EV3,... "Are also assigned to each category.

Note that "Sakura 1", "Sakura 2" and "Sakura 3"
The first meaning (11111) and the second meaning (1111)
112) and the third meaning (11113). “Orange 1” and “Orange 2” indicate the first meaning (9911) and the second meaning (9912) of “orange”. For example, "orange 1" represents a plant orange, and "orange 2" represents an orange color. The reason that the meaning is used instead of the word itself in cases other than proper nouns is that the same word may have a plurality of meanings.

In step F15 in FIG. 4, for example, such a classification model is generated according to a manual classification operation by the user. Then, the classification model is registered as Step F16,
That is, it is recorded in the RAM 15 (or the HDD 34). The generation / registration of the classification model in this way means that the classification of the document has been performed.

Note that, as described above, step F in FIG.
After the creation / registration of the classification model is performed as F15 and F16, the classification model is sequentially updated in accordance with automatic classification processing described later, editing of a classification item by a user, or manual classification operation. Become. When the classification model is updated, the update date and time are recorded in the classification model. FIG. 11 shows that the update date and time “19:05 on December 10, 1998
6 minutes and 10 seconds "are recorded.

4. 4. Automatic Classification Processing for Document Data 4-1 Processing Procedure In the document processing apparatus 1 of the present example, after the classification model is once created as described above, for example, the document data taken in from the outside by the communication unit 21 is automatically converted. The automatic classification process of classifying into is possible. That is, the automatic classification process described below is a process of, when the document processing apparatus 1 receives document data sent from the outside, classifying the document data with respect to a classification model. In this example, the automatic classification process described below may be performed each time one document is received, or may be performed each time a plurality of predetermined documents are received. The automatic classification process may be performed on all the documents received so far when the operation of opening is performed.

FIG. 12 shows the entire processing procedure as the automatic classification processing. Step F21 in FIG. 12 illustrates a document receiving process by the receiving unit 21 of the document processing apparatus 1. In this step F21, the receiving section 21 receives one or a plurality of documents transmitted via a communication line, for example. The receiving unit 21 sends the received document to the main body 10 of the document processing device. The control unit 11 stores the supplied document data or document data in the RAM 14 or the HDD 34.

Subsequently, the process proceeds to step F22, where the control unit 11
Creates an index for the document taken in step F21.

In step F23, the control section 11 converts each indexed document based on the classification model into
Automatic classification into one of the categories of the classification model. Then, the control unit 11 causes the RAM 14 to store the result of the classification, for example. Details of the automatic classification will be described later.

In step F24, the control unit 11 updates the classification model based on the result of the automatic classification of a new document in step F23. Then, in step F25, the control unit 11 registers the classification model updated in step F24. For example, the classification model is stored in the RAM 14.

By the above-described processing in FIG. 12, the automatic classification processing is performed so that the document data input to the document processing state 1 is classified on the classification model. That is, in this automatic classification process, an index is created for the received document, and after the automatic classification is performed, proper nouns, meanings,
The document address and the like are associated with a certain category on the classification model as shown in FIG. 11 (the classification model is updated).

The processes in steps F21 and F22 are the same as steps F11 and F12 in the above-described manual classification process. That is, as the index creation processing in step F22, the processing described with reference to FIGS. 5 to 8 is performed, and a repeated description thereof will be omitted. The update of the classification model in step F24 depends on the classification result of the automatic classification in step F23. Hereinafter, automatic classification in step F23 will be described in detail as processing different from the above-described manual classification processing.

4-2 Automatic Classification FIG. 13 shows the detailed processing of the automatic classification in step F23 in FIG. In step F61 of FIG.
Defines the number of intersections of the set of proper nouns included in the category Ci of the classification model and the set of proper nouns among the words extracted from the document received in step F21 and put into the index by P ( Ci). Then, the control unit 11 calculates the number P (Ci) thus calculated.
Is stored in the RAM 14.

In step F62, the control unit 11
Refers to the degree of association between all meanings included in the index of the document and all the meanings included in each category Ci by referring to the table of association between meanings shown in FIG. The total sum R (Ci) of the degrees is calculated. That is, the control unit 11 calculates the total sum R (Ci) of the degrees of association between all the meanings of words other than the proper noun in the classification model. The control unit 11 then calculates the total sum R (C
i) is stored in the RAM 14.

Here, the degree of association between meanings will be described. The degree of association between meanings may be calculated in advance for the meanings included in the electronic dictionary included in the document processing apparatus 1 by the processing in FIG. 14 and the result may be stored as shown in FIG. That is, if the control unit 11 executes the process of FIG. 14 once in advance, it can be used in the automatic classification process of FIG.

The processing of FIG. 15 executed by the control unit 11 in advance is as follows. First, in step F71, the control unit 11 uses the description of the meaning of a word in the electronic dictionary and creates a meaning network using this dictionary. That is, a meaning network is created from the reference relation between the explanation of each meaning in the dictionary and the meaning appearing in the explanation.
The internal structure of the network is described by tagging as described above. For example, the control unit 11 of the document processing apparatus sequentially reads meanings and descriptions of the electronic dictionary stored in the RAM 14 and creates a network. The control unit 14 causes the RAM 14 to store the meaning network created in this manner.

The network is not only created by the control unit 11 of the document processing apparatus using a dictionary, but also by the receiving unit 21.
The recording / reproducing section 31 reproduces the data received from the outside from the recording medium 32. Further, the electronic dictionary can be obtained by receiving from the outside by the receiving unit 21 or by reproducing from the recording medium 32 by the recording / reproducing unit 31.

In Step F72, Step F7
The central activity value corresponding to each semantic element is spread on the semantic network created in step 1. By this activity diffusion, the central activity value corresponding to each meaning is given according to the internal structure by tagging given by the dictionary. The diffusion processing of the central activity value is the processing described with reference to FIG.

In Step F73, Step F7
One semantic Si constituting the semantic network created in 1 is selected, and in the subsequent step F74,
The initial value of the central activity value ei of the vocabulary element Ei corresponding to this meaning Si is changed, and the difference △ ei of the central activity value at this time is calculated.

Further, in step F75, a difference Δej of the central activation value ej of the element Ej corresponding to another meaning Sj corresponding to the difference Δei of the central activation value ei of the element Ei in step F74 is determined. In step F76, the difference Δe obtained in step F75
quotient ｊej obtained by dividing j by △ ei obtained in step F74
/ △ ei is the degree of association between meanings of the meaning Si with respect to the meaning sj.

In step F77, one meaning Si
It is determined whether or not the calculation of the degree of association between meanings has been completed for all pairs of the word and another meaning Sj. When the calculation of the relevance between meanings is not completed for all pairs of meanings, the process returns to step F73, and the calculation of the relevance between meanings is continued for the pairs for which the calculation of the relevance is not completed. In the loop from step F73 to step F77, the control unit 11 sets a necessary value to, for example, RA
M14 is sequentially read out, and the degree of association between meanings is calculated as described above. The control unit 11 causes the RAM 14 to sequentially store the calculated meaning-to-sense associations, for example. Then, when the calculation of the degree of inter-word meaning is completed for all the word-sense pairs, this series of processing is ended from step F77.

The calculation of the degree of association between meanings is performed by a certain one.
It can be said that, when the central activity value of one meaning is changed, the meaning in which the central activity value changes along with the meaning has a high degree of relevance. That is, if the central activity value of a certain meaning is changed in step F74, the central activity value of the related (linked) meaning changes accordingly, and if the degree of the change is examined, a certain meaning is obtained. The degree of relevance of each other meaning with respect to is understood. (The central activation value of an element Ei reflects the central activation value and the endpoint activation value of the linked element as described in the above description of the activity diffusion, and the element Ei endpoint activation value is updated. In addition, since the value is obtained from the sum of the end point activity value of the element Ei and the current center activity value, the larger the degree of association with the link destination is, the larger the amount of change of the center activity value is.) By performing the processing for all other meanings, it is possible to calculate the degree of association for all pairs (combinations) of meanings.

The calculated degree of association between meanings is defined between each meaning as shown in FIG. In the table of FIG. 15, the degree of association between meanings is normalized to take a value from 0 to 1. In this table, as an example, the degree of inter-semantic association between “computer”, “television”, and “VTR” is shown. The relevance between meanings of "computer" and "television" is 0.55, the relevance between meanings of "computer" and "VTR" is 0.25, and the relevance between meanings of "television" and "VTR" is 0.60. It is.

When the processing of step F62 in FIG. 13 is performed using the degree of association between the meanings calculated in advance as described above, the control unit 11 then proceeds to step F63 where the inter-document classification of the document with respect to the category Ci is performed. Relevance Rel (C
i) is calculated as Rel (Ci) = m1P (Ci) + n1R (Ci). Here, the coefficients m1 and n1 are constants and represent the degree of contribution of the respective values to the inter-document-class relevance. The control unit 11 performs the calculation of the above expression using the number P (Ci) of common sets calculated in step F61 and the sum R (Ci) of the degree of association between meanings calculated in step F62, and calculates the degree of association between document classifications. Calculate Rel (Ci). The control unit 11 causes the RAM 14 to store the thus calculated inter-document-class relevance Rel (Ci).

The values of these coefficients m1 and n1 can be, for example, m1 = 10 and n1 = 1. The values of the coefficients m1 and n1 can also be estimated using a statistical method. That is, the control unit 11 determines the degree of association Rel between document classifications for a plurality of pairs of coefficients m and n.
Given (Ci), the coefficient can be obtained by optimization.

In Step F64, the control unit 11
Is the document class relevance Rel (C
When i) is the largest and the value of the degree of association Rel (Ci) between the document classifications exceeds a certain threshold, the documents are classified into the category Ci. That is, the control unit 11 creates the inter-document-class relevance for each of the plurality of categories, and when the maximum inter-document-class relevance exceeds the cabinet value, the control unit 11 assigns the document with the maximum inter-document-class relevance. Classify into category Ci. As a result, the document is automatically classified into a required category. If the maximum degree of association between document classifications does not exceed the threshold value, no document classification is performed.

The processing shown in FIG.
If the automatic classification in step F23 is performed,
The series of automatic classification is completed by updating and registering the classification model accordingly at 24 and F25. That is, the document data received by the document processing apparatus 1 is automatically classified, and the user can confirm the received document data in a required document classification area, for example, in the classification window 201 of FIG. Become.

5. Read-aloud process Next, a process of reading aloud document data will be described. As described above, the user can browse the text of the document by selecting the document and opening the browse window 301 as shown in FIG. For example, the viewing window 301 can be opened from the classification window 201 described with reference to FIG.

For example, by clicking a browser button 202b while a certain document is selected in the classification window 201, the document display unit 3 is displayed as shown in FIG.
A browsing window 301 displaying the text of the document selected in 03 is opened. When the entire text of the document cannot be displayed on the document display unit 303, a part of the document is displayed. At the point in time when a summary sentence has not been created, the summary display section 304 is blank as shown in FIG. The creation and display operation of the summary sentence will be described later.

As described above, when the document processing apparatus 1 receives the tagged document, the document processing apparatus 1 can display the text and a summary sentence described later in detail, and present the received document to the user by voice. You can also. In other words, the CPU 13 activates a voice reading program among the electronic document processing programs recorded in the ROM 15 or the HDD 34, thereby reading the document through a series of steps as shown in FIG. . First, here, a simplified description of each step is given, and thereafter, each step is explained in detail using a specific document example.

As a process of the control unit 11, step F101 in FIG. 16 is a document receiving / storing process similar to step F11 in FIG. 4 (or step F21 in FIG. 12). As described above, the received document (tagged document) is subjected to manual or automatic classification processing. Similarly, in step S101, FIG. It is written. Here, the order of the classification process and the reading process and the like are not particularly defined as the processing procedure.

It is necessary that a document (reception document) to be subjected to the text-to-speech processing is provided with a tag necessary for performing speech synthesis, as described later. However, after receiving the tagged text, the document processing apparatus 1 can also create a document by newly adding a tag necessary for performing speech synthesis to the document. Hereinafter, the tagged document prepared by receiving or creating in this manner is referred to as a tag file.

In the document reading process of the document processing apparatus 1, subsequently, in step F102, a reading file is generated based on the tag file under the control of the CPU 13. As will be described later, the reading file is generated by deriving attribute information for reading from a tag in the tag file and embedding the attribute information.

Subsequently, in step F103, under the control of the CPU 13, the document processing apparatus 1 performs processing suitable for the speech synthesis engine using the reading file.
The speech synthesis engine may be configured by hardware or may be realized by software. When the speech synthesis engine is realized by software, the application program is stored in the ROM 15 or the HDD 34 in advance.

Subsequently, the document processing apparatus 1 proceeds to step F104.
In, processing is performed according to an operation performed by a user using a user interface described later. Document processing device 1
Can read out a given document by performing such processing. Each of these steps will be described in detail below.

First, reception or creation of a tagged document in step F101 will be described. The document processing apparatus 1 receives, for example, a document (a document to which a tag required for performing speech synthesis has already been added) from the communication unit 21. Alternatively, the document processing apparatus 1 receives a tagged document, and newly adds a tag necessary for performing speech synthesis to the document to create the document.

As an illustrative example, it is assumed that the following tag file in which Japanese and English documents are tagged is received or created.

First, a Japanese document serving as a source of a tag file is as follows. "[Nice aging] /
8 cancer metastases can be suppressed! ? Cancer has been the leading cause of death in Japan for more than a decade. The mortality rate is increasing with age. When thinking about the health of the elderly, you cannot avoid cancer. Characterizing cancer is cell proliferation and metastasis. There are two types of human cells: "cancer genes", which act as accelerators in automobiles and rapidly grow cancer, and "cancer suppressing genes" that act as brakes. There is no problem if both are balanced. Loss of normal regulatory function and nonbreaking mutations in the cell initiate cancer growth. In the elderly, the mutation accumulates over the years, increasing the proportion of cells with cancerous conditions, leading to more cancers. By the way, without the other characteristic, metastasis, cancer doesn't have to be so afraid. This is because a complete cure is possible just by resection. Here is the importance of suppressing metastasis. This metastasis does not occur simply by increasing the number of cancer cells.
Cancer cells dissolve proteins (proteins) between cells, create their own way, and enter blood vessels and lymph vessels. In recent years, it has been elucidated that complicated movements such as searching for a new “dwelling house” while circulating are performed. "

An example of an English document serving as a source of a tag file is as follows: "During its centennial year, The Wall Street Jour
nal will report events of the past century that st
and as milestones of American business history.TH
REE COMPUTERS THAT CHANGED the face of personal co
mputing were Iaunched in 1977. That year the Apple
II, Commodore Pet and Tendy TRS came to market.T
he computers were crude by today's standerds.Appl
e ll owners, for example, had to use their televisi
on sets as screens and storeddata on audiocassette
s. "

When the document processing apparatus 1 receives a document to which such a Japanese or English document is tagged,
It is possible to perform the classification process, display the text as shown in FIGS. 26 and 27 described later, or create and display a summary sentence.

Here, the above-mentioned Japanese or English documents are each constituted as a tag file as shown in FIG. 18 or FIG. As a tag file of a Japanese document, FIG. 18 (a) shows an excerpt of the heading “[nicely aging] / 8 cancer metastasis, suppressed !?”, and FIG. 18 (b) It shows an excerpt from the last paragraph in the document, "This metastasis, cancer cells are being elucidated in recent years." The remaining paragraphs have been omitted. It should be noted that the actual tag file is composed of one file from the heading to the last paragraph.

In the heading portion shown in FIG.
The tag <heading> indicates that this part is a heading. The tag files shown in FIGS. 18A and 18B are basically attached with tags in the same manner as the tag file example used when the document data structure was described with reference to FIG. Although a detailed description of each of the above-described tags is omitted, tags required for performing speech synthesis are added to required locations.

For example, first, as shown in the portion of “Example 1” in the figure,
Some are given when information indicating a reading pseudonym is given to the original document, such as “protein”.
In other words, in this case, the pronunciation = “nul
Reading attribute information “l” is described, and a tag for prohibiting partial reading of “(tanpaku)” is added. Also, the tags required to perform speech synthesis include:
As shown in the "Example 2" and "Example 3" in the figure, technical terms such as "lymphatic vessels" and difficult-to-read parts such as "dwelling house" that may be read aloud incorrectly There is. In other words, in this case, "Rinpakuda" or "Sumie"
In order to prevent the pronunciation from being read out, pronunciation attribute information indicating the pronunciation pseudonym of pronunciation = “Rinkan” and pronunciation = “Sumika” is described.

On the other hand, as a tag necessary for performing speech synthesis in the tag file shown in FIG. 19, as shown in a portion shown as “Example 4” in the figure, a pronunciation = “ Two ”reading attribute information is described. This is described in order to prevent "II" from being read out as "second" when it is desired to be read out as "two".

For example, if a document includes a quote, such a tag file includes, although not shown,
A tag indicating that the sentence is a quote is attached. Further, when there is a question sentence in the document, for example, a tag indicating that the sentence is a question sentence is added to the tag file, though not shown.

In step F101 shown in FIG. 16, the document processing apparatus 1 receives or creates a document to which a tag necessary for performing speech synthesis has been added as in the above example. .

Next, the generation of a reading file in step F102 of FIG. 16 will be described. The document processing device 1 derives attribute information for reading out from a tag in the tag file, and generates a reading-out file by embedding the attribute information. Specifically, the document processing apparatus 1 finds tags indicating the beginning of a paragraph, a sentence, or a phrase of a document, and embeds attribute information for reading aloud in correspondence with these tags. When the document processing apparatus prepares the summary of the document, the head of the part included in the summary is found from the document, and the attribute information for increasing the volume at the time of reading out is embedded. Can be emphasized.

The document processing device 1 generates a reading file as shown in FIG. 20 or 21 from the tag file shown in FIG. 18 or FIG. FIG. 20 (a)
(B) corresponds to the portion shown in FIGS. 18 (a) and (b). It goes without saying that the actual reading file is composed of one file from the above-mentioned heading portion to the last paragraph.

In the reading file shown in FIG. 20, attribute information of Com = Lang *** is embedded corresponding to the head of the document. This attribute information indicates the language describing the document. Here, the attribute information is Com = Lang = JPN, indicating that the language describing the document is Japanese. In the document processing apparatus, by referring to the attribute information, it is possible to select an appropriate speech synthesis engine corresponding to the language for each document.

The read-out file has embedded therein attribute information such as Com = begin_p, Com = begin_s, and Com = begin_ph. These pieces of attribute information indicate the beginnings of paragraphs, sentences, and phrases of the document, respectively. The document processing device 1 identifies the beginning of these paragraphs, sentences, and phrases based on the tags in the tag file described above. In the reading file, for example, portions where tags representing syntactic structures of the same level appear continuously, such as <adjective verb phrase><nounphrase> in the above-described tag file, correspond to each. Without the number Com = begin_ph being embedded,
It is put together and one Com = begin_ph is embedded.

Further, the read-out file includes Com = be
Attribute information of Pau = 500, Pau = 100, and Pau = 50 is embedded corresponding to gin_p, Com = begin_s, and Com = begin_ph, respectively. These pieces of attribute information indicate that pause periods of 500 ms, 100 ms, and 50 ms are provided for reading out. That is, the document processing apparatus 1 provides pauses of 500 ms, 100 ms, and 50 ms at the beginning of a paragraph, a sentence, and a phrase of a sentence, respectively, so that the document is read out by the speech synthesis engine. Information. Note that these pieces of attribute information are embedded corresponding to Com = begin_p, Com = begin_s, and Com = begin_ph. Therefore, for example, a portion where tags representing the same level of syntactic structure appear continuously, such as <adverb phrase><nounphrase> in the tag file, is regarded as one phrase, and the corresponding number of Pau = One Pau = 50 is embedded together without being embedded. Also,
For example, Pau = *** is embedded in portions where tags representing different levels of syntactic structure appear continuously, such as <paragraph><sentence><nounphrase> in the tag file. Therefore, when reading out such a portion, the document processing apparatus 1 provides a pause period of 650 milliseconds obtained by adding the pause periods of the paragraphs, sentences, and phrases of the document, for example. in this way,
By providing a pause period corresponding to a paragraph, a sentence, and a phrase, the document processing apparatus 1 can perform reading without discomfort in consideration of a break between the paragraph, the sentence, and the phrase. This pause period does not need to be 600 ms, 100 ms, and 50 ms at the beginning of the paragraph, sentence, and phrase of the document, respectively, and can be changed as appropriate.

Further, in the reading-out file, “(protein)” is removed and the pronunciation = “rin” corresponding to the pronunciation attribute information of pronunciation = “null” described in the tag file. According to the reading attribute information of "kan" and pronunciation = "Sumika", "lymphatic vessels"
"Dwellers" are "Rinkan" and "Sumika", respectively.
Has been replaced by By embedding such reading attribute information, the document processing device 1 prevents reading errors due to inadequate dictionaries referenced by the speech synthesis engine.

Further, in the reading-out file, attribute information for designating only this quotation to use another speech synthesis engine based on a tag indicating that the quotation is included in the document is included. It may be embedded. Further, attribute information for raising the intonation of the ending of the sentence may be embedded in the reading-out file based on a tag indicating that the sentence is a question sentence. Furthermore, in the reading-out file, if necessary, attribute information for converting a so-called "Dama-tona" style to a "Dama-tona" style can be embedded. In this case, instead of embedding such attribute information in the reading-out file, the document processing apparatus 1 converts the style of "Dana-tona" into the style of "Dan-Ma-tona" and converts the speech reading-out file. You may make it generate | occur | produce.

On the other hand, in the read-out file shown in FIG. 21, attribute information Com = Lang = ENG is embedded at the beginning of the document, indicating that the language describing the document is English. ing. The attribute information of Com = Vol = *** is embedded in the file for reading out.
This attribute information indicates the volume at the time of reading. For example,
Com = Vol = 0 indicates that the text is read out at the default volume of the document processing apparatus. Com = Vol = 80 indicates that the default volume is read out at a volume increased by 80%. Any Com = Vol = *** is valid until the next Com = Vol = ***. Further, in the reading file, "II" is replaced by "two" in accordance with the reading attribute information of pronunciation = "two" described in the tag file.

The document processing apparatus 1 generates such a reading file through a series of steps shown in FIG. First, the document processing apparatus 1 executes step F201.
The CPU 13 analyzes the received or created tag file. Here, the document processing apparatus 1 determines the language in which the document is described, and searches for the head of the paragraph, sentence, and phrase of the document, and the reading attribute information based on the tag. Subsequently, in step F202, the document processing apparatus 1 embeds attribute information Com = Lang = *** at the head of the document by the CPU 13 in accordance with the language in which the document is described.

Next, the document processing apparatus 1 executes step F203.
, The CPU 13 replaces the head of the paragraph, sentence and phrase of the document with the attribute information in the reading file. That is, the document processing apparatus 1 replaces <paragraph>, <sentence>, and <*** phrase> in the tag file with Com = begi
Replace with n_p, Com = begin_s and Com = begin_ph.

Further, the document processing apparatus 1 executes step F20.
In 4, the same level of syntactic structure appears by the CPU 13 and the same Com = begin _ ***
Combine into one Com = begin _ ***. Subsequently, in step F205, the document processing apparatus 1 embeds Pau = *** in correspondence with Com = begin _ *** by the CPU 13. That is, the document processing apparatus 1 embeds Pau = 500 before Com = begin_p, embeds Pau = 100 before Com = begin_s,
Embed Pau = 50 before gin_ph. And the document processing device 1
Is determined by the CPU 13 in step F206.
Replace with correct reading based on reading attribute information. That is, the document processing apparatus 1 removes “(protein)” based on the pronunciation attribute information “pronunciation =“ null ”, and based on the pronunciation attribute information“ pronunciation = “Rinkan” and pronunciation = “Sumika”. "Lymphatic vessels", "houses"
Substitute “Rinkan” and “Sumika”, respectively.

In step F102 shown in FIG. 16, the document processing apparatus 1 automatically generates a reading file by performing the processing shown in FIG. The document processing device 1 causes the RAM 14 to store the generated reading file.

Next, the processing using the reading file in step F103 of FIG. 16 will be described.
The document processing device 1 uses the read-out file to
Under the control of the CPU 13, processing suitable for the speech synthesis engine stored in advance in the M15, the HDD 34, or the like is performed.
Specifically, the document processing apparatus 1 selects a speech synthesis engine to be used based on the attribute information of Com = Lang = *** embedded in the reading file. The speech synthesis engine is provided with an identifier according to the type of language or male / female voice, and the information is recorded in the HDD 34 as, for example, an initialization file. The document processing device 1 refers to the initialization file and selects a speech synthesis engine having an identifier corresponding to the language. .

The document processing apparatus 1 converts Com = begin _ *** embedded in the file for reading out into a format suitable for the speech synthesis engine. For example, the document processing device 1
Mark Com = begin_ph with a number in the 10000s, such as Mark = 10000. Also mark Com = begin_s with a number in the 1000s, such as Mark = 1000, and Com = begin_p
Is marked with a number in the 100s, such as Mark = 100. This means that the heads of <phrase>, <sentence>, and <paragraph> are indicated by numbers in the 10000s, 1000s, and 100s, respectively.
The head of <sentence> and <paragraph> can be identified. Furthermore, in the reading file, the volume attribute information is
Since the volume is represented by the default volume percentage such as Voll = ***, the document processing apparatus 1 converts the percentage information into absolute value information based on the attribute information and obtains the absolute value information.

In step F103 shown in FIG. 16, the document processing apparatus 1 performs the processing using such a file for reading out, so that the speech synthesis engine can read out the file for reading out. Format.

Next, the operation using the user interface in step F104 of FIG. 16 will be described. The document processing apparatus 1 activates the speech synthesis engine when the user operates, for example, a mouse or the like of the input unit 20 and clicks on the read-aloud button 306c shown in FIG. Then, the document processing apparatus 1 displays a reading window 401 for a user interface on the display unit 30 as shown in FIG.

As shown in the figure, the read-out window 401 has a play button 42 for reading out a document.
0 and a stop button 421 for stopping reading out
And pause button 4 to pause reading aloud
22. In addition, the reading window 401
Are a cue button 411, a fast rewind button 412, and a fast forward button 413 for cueing, fast rewinding, and fast forwarding in sentence units, a cueing button 414 for cueing, fast rewinding, and fast forwarding in paragraph units, and a fast rewinding button. A button 415 and a fast forward button 416, and a cue button 417 and a fast reverse button 4 for cueing, fast rewinding, and fast forwarding in phrase units
18 and a fast forward button 419.

Further, a reading window 401 is provided with a selection switch 4 for selecting whether to read a whole sentence or a summary sentence created as described above.
23,424. Further, an image display area 403 for displaying an image at the time of reading is set, and an image of a person who is reading is displayed, and a telop display area 402 is displayed.
Is provided so that characters can be displayed in a telop corresponding to the reading voice.

Although not shown here, for example, it has buttons for increasing / decreasing voice, buttons for increasing / decreasing reading speed, buttons for changing voices such as male / female voices, and the like. Is also good.

The document processing apparatus 1 performs a reading operation by the speech synthesis engine in response to the user clicking / selecting these various buttons / switches by operating the mouse or the like of the input unit 20, for example. For example, the document processing device 1
Starts reading the document by clicking the play button 420 by the user. Specifically, the control unit 1
1 supplies the audio signal generated by the audio synthesis processing to the audio output unit 33 and outputs it as audio. In addition, the document processing apparatus 1 stops or pauses the reading process when the stop button 421 and the pause button 422 are clicked.

When the user presses the cue button 411 during the reading, the user jumps to the head of the currently read sentence and reads the sentence again. Cue button 4
In the same manner, for 14 and 417, the program jumps to the beginning of the currently read paragraph or phrase, and is read again. The control unit 11 controls the cue buttons 411, 414,
Regarding the operation 417, the jump destination is recognized by the above-mentioned marking. In other words, when the cue button 411 relating to a sentence is operated, the control unit 11 traces the sentence back from the middle position of the sentence currently being read out.
Search for 000's mark. When a mark in the 1000's range is detected, reading out is resumed from there. In the case of paragraphs and phrases,
Reading is resumed by looking for a mark in the 10000s range. By such processing, for example, it is possible to respond to a request that a user wants to repeatedly reproduce a desired portion in a document.

The document processing apparatus 1 executes the processing in step F1 in FIG.
At 04, in response to the user performing an operation using the user interface in the reading window 401, the text-to-speech engine reads the document. In this manner, the document processing apparatus 1 can read out a desired document by the speech synthesis engine without any discomfort.

By the way, the document to be read may be the body of the document data, or may be a summary sentence generated as described later. The text or the summary text is selected by clicking the selection switches 423 and 424. In any case, the processing in steps F102 and F103 in FIG. The text-to-speech by the speech synthesis engine becomes possible.

In this example, the reading file is generated from the received or created tag file.
Instead of generating such a reading file, reading may be directly performed based on the tag file.
In this case, after receiving or creating the tag file, the document processing device 1 uses a speech synthesis engine and, based on tags indicating paragraphs, sentences, and phrases attached to the tag file,
A certain pause is provided at the beginning of a paragraph, sentence or phrase to read out. By doing so, the document processing device 1
Can be read directly based on the tag file without generating a voice reading file.

6. Summary Creation / Display Process Next, a process of creating a summary sentence for document data will be described. As described above, the user can browse the text of the document by selecting the document and opening the browse window 301 as shown in FIG. In the browsing window 301, the text and the summary of the selected document are displayed. However, at the point in time when a summary sentence has not been created, the summary display unit 304 is blank as shown in FIG. Note that the example described here assumes that the document is displayed horizontally. (An example of vertical writing will be described later.)

When the user clicks on the summary creation button 306a in the browsing window 301, the document display unit 30
A summary sentence for the document displayed in 3 is created,
This is displayed on the summary display unit 304 as shown in FIG. That is, the control unit 11 responds to the user's summary creation operation by
A summary sentence creation process as described below is performed, and after creation, control for displaying the summary sentence is performed. The process of creating an abstract from a document is performed based on the internal structure of the document by tagging.

The summary sentence is usually displayed in the summary display section 304.
Is generated according to the size of And a text display unit 303
And the area of the summary display section 304 is determined by the user
Can be changed by moving. That is, the summary sentence is displayed in the summary display unit 30 at the time when the summary creation is instructed.
4 is created with a size (document length) corresponding to the size of the document No. 4. For example, in FIG. 26, the summary display unit 304 is very narrow, but when the user moves the partition frame 312 to widen the summary display unit 304 and instructs the creation of a summary, for example, as shown in FIG. A summary sentence having a document length corresponding to the area size is created and displayed on the summary display unit 304 expanded as described above.

The entire size of the window itself displayed on the screen can be reduced or widened by moving the outer frames 313 and 314 using a mouse or the like by the user. As described above, the user can set an arbitrary window range on the screen by operating the partition frame 312 and the outer frames 313 and 314. From this, for example, the user can set the area as the text display unit 303 and the summary display unit 304. Can be arbitrarily set by the user. Further, the aspect ratio of the area changes according to the setting. For example, the shape of the area as the summary display unit 304 can take various shapes as shown in FIGS. 31 (a) to 31 (e), for example. FIG. 31 (a) to (c)
FIG. 31 shows an example in which the area of the summary display unit 304 has a relatively small aspect ratio (vertical y / horizontal x).
(D) and (e) are examples in which the value of the aspect ratio becomes relatively large. Of course, FIG. 31 is a partial example of an actual area shape, and other various area shapes can be realized.

Here, as shown in FIGS. 31 (a) to 31 (c),
When the summary display section 304 is considerably longer in the horizontal direction than in the vertical direction, the user may have difficulty reading the text in a normal display, and the summary text is displayed as a telop, that is, the document is switched or moved. There is a situation that it is easier for the user to see. Further, a case where the length is long in the horizontal direction means that the number of lines is not so large in the vertical direction, and therefore, the document length that can be displayed at one time is often short. In this case, since an abstract cannot be created with a sufficient document length, the sentence may not substantially function as an abstract. Therefore, in this example,
The aspect ratio of the display area as the summary display unit 304 is determined, and if the display area is extremely long in the horizontal direction, a summary sentence having a document length exceeding the size of the summary display unit 304 is created. And display it.

Hereinafter, the operation of creating and displaying a summary sentence of this example including such a telop display will be described.

When the user clicks on the summary creation button 306a on the browsing window 301, the control unit 11 starts the summary creation processing shown in FIG. When the summary creation processing of FIG. 23 ends, the summary sentence display processing of FIG. 24 is subsequently executed, and in some cases, the telop display processing of FIG. 25 is performed during the summary sentence display processing.

In the digest creation processing of FIG. 23, first, in step F81, the control unit 11 performs active diffusion. In this example, the document is summarized by employing the central activity value obtained by the activity diffusion as the importance. That is, in a document given an internal structure by tagging, by performing active diffusion, a central activation value corresponding to the internal structure by tagging can be given to each element. The active diffusion process performed in step F81 is the same as the process described with reference to FIGS.
As described above, the active diffusion is a process of giving a high central activity value to an element related to an element having a high central activity value. That is, the active diffusion is an operation on the central activity value such that the central activity value is equal between the anaphor (co-reference) expression and its antecedent, and the central activity value attenuates otherwise. Since the central activity value is determined according to the internal structure by tagging, it can be used for analyzing a document in consideration of the internal structure by tagging.

Next, in step F82, the aspect ratio of the summary display section 304 at that time is confirmed, and it is confirmed whether or not the value as the aspect ratio is equal to or greater than a predetermined value Rth. The aspect ratio means, for example, the number of lines that can be displayed in the summary display unit 304 as a vertical value y, and the number of characters that can be displayed in a line as a horizontal value x.
What is necessary is just to calculate as y / x. Since the size of the character itself is set on the system at that time, the number of lines that can be displayed when the area of the summary display unit 304 is a certain value and the number of characters in one line are uniquely determined. Things.
The predetermined value Rth is a threshold for judging whether or not the shape of the summary display section 304 is extremely long, and the value of the aspect ratio as a limit at which the user is not determined to be extremely long is set. Is set. As the specific value as the predetermined value Rth, an appropriate value is determined based on system design.

First, the case where the aspect ratio is equal to or greater than a predetermined value Rth will be described. This is the case where the summary display unit 304 has a shape recognized as normal to some extent, for example, as shown in FIGS. 31D and 31E. In this case, a document corresponding to the size of the summary display unit 304 is used. This is a process for creating a long summary sentence.

In this case, the process of the control unit 11 proceeds to step F83, where the control unit 11 executes the summary display unit 30 of the browsing window 301 currently displayed on the display unit 30.
The size wsy (specifically, the maximum number of characters that can be displayed on the summary display unit 304) of the number 4 is set as a variable (maximum number of characters) ws. Further, the control unit 11 initializes a summary character string (an internal register that holds a summary sentence) s to an initial value s (0).
= ”Is set. Further, a flag Ft indicating execution of telop display described later is set to “0”, that is, off. The control unit 11 records the maximum number of characters ws and the initial value s (0) of the character string s thus set in the RAM 14.

Next, the process proceeds to step F85, where the control unit 11
Sets the count value i of the counter that counts the sentence skeleton extraction process to “1”. Then, in step F86, the control unit 11 extracts the skeleton of the sentence having the i-th highest average central activity value from the sentence based on the count value i of the counter. The average central activity value is the average of the central activity values of the elements constituting one sentence. Control unit 11
Is, for example, a character string s (i-1) recorded in the RAM 14.
Is read out, and the character string of the skeleton of the extracted sentence is added to this character string s (i-1) to obtain S (i). Then, the control unit 11 converts the character string s (i) thus obtained into R
Record in AM14. In the first time, since the character string s (i-1) has the initial value s (0), the skeleton of the sentence extracted this time is stored in the RAM 14 as the character string S (i).
When the process of step F84 is performed thereafter, the skeleton of the extracted sentence is changed to the character string S (i), and the character string S (i) up to that point (that is, the character string S (i-
1)). At the same time, the control unit 11 determines in this step F84 a list L (i) of the elements not included in the skeleton of the sentence in the order of the central activation value.
And the list L (i) is recorded in the RAM 14.

That is, in step F86, the summarization algorithm uses the result of activity diffusion to
The sentences are selected in descending order of the average central activity value, and the skeleton of the selected sentence is extracted. The skeleton of a sentence is composed of essential elements extracted from the sentence. Required elements can be the head of the element, the subject, the object (obj
ect), indirect object, owner (poss
An element having a relationship attribute of essor, cause, condition, or comparison, and an element directly included when the coordination structure is an essential element, constitute an essential element. Then, by connecting the essential elements of the sentence, a skeleton of the sentence is generated and added to the summary.

At step F87, the control section 11 determines whether or not the length of the character string s (i) is larger than the maximum number of characters ws of the summary display section 104 of the browsing window 301.
This step F87 is a determination process for creating a summary sentence according to the size of the summary display unit 304.

When the length of the character string s (i) has not reached the maximum number of characters ws, the control section 11 executes the processing in step F
Proceed to 88. In step F88, the control unit 11 determines in the document the central activity value of the element of the sentence having the (i + 1) -th highest average central activity value and the highest central activity value of the list L (i) created in step F86. Compare the central activity values of the elements. That is, the sentence having the next highest average central activity value after the sentence adopted as the summary in step F86 (that is, the sentence which is a candidate to be added to the next summary sentence) and the sentence adopted as the summary in step F86 The central activity values of elements excluded from the summary as not scaffolds are compared.

In the process of step F88, the part to be added next to the character string as the summary sentence is set in the immediately preceding step F88.
This is a process of determining whether to select from sentences not adopted as a skeleton in the sentence adopted in 86 or to select from other sentences.

In the sentence having the (i + 1) -th highest average central activation value, the list L
If the highest central activity value in (i) is the higher central activity value, the portion to be added next to the character string as the summary sentence is used as the skeleton in the sentence immediately preceding step F86. Try to choose from those that have not been adopted. Therefore, the process of the control unit 11 proceeds to step F90, in which the element having the highest central activity value in the list L (i) is stored in the character string S (i) stored at that time
And a character string SS (i). At this time, the element added to the character string SS (i) is deleted from the list L (i). Then, in step F91, the character string S
It is determined whether S (i) is greater than the maximum number of characters ws. If not, the process returns to step F88.

In step F88, if the (i + 1) -th element having the highest central activity value is higher than the highest central activity value in the list L (i) as the element of the sentence having the highest average central activity value, the summary sentence In step F89, the part to be added next to the character string is selected from a sentence different from the sentence adopted in step F86 immediately before.
, The count value i is incremented, and the process returns to step F86. That is, in step F88, (i + 1)
For the sentence having the second highest average central activity value, the skeleton is extracted in step F86 and added to the character string S (i).

As described above, in step F86 or step F90, while adding elements to the character string based on the element having the higher central activity value as the element or the other element serving as the skeleton of the sentence in step F86 or step F90.
1, the character string S (i) or SS (i) is converted to the maximum number of characters ws
By comparing with, a character string close to the maximum number of characters ws but not exceeding the maximum number of characters ws is created.

For example, if the character string S (i) exceeds the maximum number of characters ws in step F87, the process of the control unit 11 proceeds to step F92, and the character string S (i- 1) is a summary sentence. In other words, this means that the maximum number of characters ws has been exceeded by adding the skeleton of the sentence in step F86.
The character string S (i-1) before adding the skeleton is determined to be a character string that is close to the maximum number of characters ws but does not exceed the maximum number of characters ws, and is used as a summary sentence.

When the character string S (i) exceeds the maximum number of characters ws in step F87 when the character string S (i) is first generated in step F86 (i = 1) at step F87, Since the character string S (i-1) becomes the character string S (0) as the initial value set in step F83, a summary sentence could not be created substantially. This is because the size of the summary display unit 304 is too small. Therefore, the user enlarges the area of the summary display unit 304 on the screen, and then clicks the summary creation button 306a again to return to FIG. What is necessary is just to make a process start.

If the character string S (i) does not exceed the maximum number of characters ws in step F87, as described above, the control unit 1
The process of step 1 proceeds to step F88, in which the next portion to be added to the character string is determined. When the process proceeds to step F91 as described above, it is determined whether or not the character string SS (i) has exceeded the maximum number of characters ws. Where the string SS
If (i) exceeds the maximum number of characters ws, the process of the control unit 11 proceeds to step F93, and the character string S (i) before adding a certain element in the immediately preceding step F90 is used as a summary sentence. Become. In other words, this means that the maximum number of characters ws has been exceeded by adding the element in step F90. Therefore, the character string S (i) before the addition of the element is close to the maximum number of characters ws but is not the maximum number of characters ws. Is determined to be a character string that does not exceed, and is used as a summary sentence.

The above processing has been described as the processing performed when the aspect ratio of the summary display unit 304 is equal to or more than the predetermined value Rth in step F82 and the process proceeds to step F83. Therefore, in this case, at the time when the processing in FIG. 23 ends, a summary sentence suitable for the size of the summary display unit 304 at that time is created. The contents of the summary sentence include the skeleton of one or more sentences having a high average central activity value and elements having a high central activity value other than the skeleton. When a summary sentence suitable for the size of the summary display unit 304 is created in this way, the summary sentence is stored in the RAM 14 and is processed by the next processing in FIG.
, The entire summary sentence is fixedly displayed on the summary display section 304.

That is, when the digest creation process of FIG. 23 is completed, the process of the control unit 11 proceeds to the digest sentence display process of FIG. In the summary sentence display processing, first, step F94
Then, it is determined whether or not the flag Ft is “1” (ON). As described above, in this case, the flag F is set in step F83.
This is the case where t = 0 and a summary sentence suitable for the size of the summary display unit 304 at that time is created by the above-described processing. Therefore, in this case, the process proceeds to step F96, and the created summary sentence is displayed on the summary display unit 30.
4 is displayed. As a result, the entire summary sentence is displayed as shown in FIG. That is, the user sets the summary display unit 3 in advance.
By instructing the creation of a summary after arbitrarily setting the size of the document 04, the summary of the document length according to the size of the summary display unit 304 is fixed (that is, without being switched or moved).
Will be displayed.

When the user looks at the displayed summary and wants to see a more detailed summary, or wants to see a shorter summary, the browsing window 30 is displayed.
After increasing or decreasing the size (area) of the first summary display unit 304, the user may click the summary creation button 306a again. Then, the aspect ratio of the summary display unit 304 becomes the predetermined value Rt.
As long as the length is equal to or longer than h, a summary having a document length corresponding to the size of the summary display unit 304 at that time is created and displayed by the above-described processing of FIG.

By the way, for example, when the user clicks the summary creation button 306a in a state where the summary display section 304 has a very long horizontal shape as shown in FIG. 26, the summary creation processing of FIG. 23 is started. If it is determined in step F82 that the aspect ratio of the summary display unit 304 is smaller than the predetermined value Rth, the following processing is performed.

In this case, the processing of the control unit 11 proceeds to step F
Proceeding to 84, a preset fixed value wsfix is substituted as the maximum number of characters ws. The fixed value wsfix is a value corresponding to the number of characters set as a minimum required as a summary sentence, and an appropriate value is set in terms of system design. Note that the fixed value wsfix = (wsset)
・ V is set, and a fixed value wsse is set in the control unit 11.
The value of the fixed value wsfix may be arbitrarily changed by the user by holding t and allowing the user to input the coefficient V.

In step F84, the control section 11 initializes a summary character string (an internal register for holding a summary sentence) s and sets an initial value s (0) = “”.
Further, the flag Ft is set to 1 (ON). The control unit 11
The maximum number of characters ws and the initial value s (0) of the character string s set in this way are recorded in the RAM 14.

Subsequently, the control unit 11 sets the variable i to 1 in step F85, and then proceeds to the processing after step F86.
Since this is as described above, repeated description will be avoided. That is, also in this case, a summary sentence having the number of characters closest to the maximum number of characters ws is created without exceeding the maximum number of characters ws. However, in this case, the maximum number of characters ws = w
sfix, the summary display unit 30 at that time is displayed.
Therefore, a summary sentence having a number of characters (document length) exceeding the number of characters that can be displayed on the summary display unit 304 is not generated.

When the summary sentence is created by the processing of steps F86 to F93, the control unit 11 executes the summary sentence display processing of FIG. In this case, since the flag = 1, the process proceeds from step F94 to F95, and a process of displaying the generated summary sentence as a telop is performed.

FIG. 25 shows an example of the telop display processing in step F95 in detail. First, the control unit 11 executes step F
At 501, a variable n = 1 is set. And step F5
In step 02, the n-th sentence is extracted from the generated summary sentence. Therefore, first, the first sentence constituting the summary sentence is extracted.

Next, in step F503, it is determined whether or not the sentence length Ls (the number of words) of the extracted sentence exceeds the summary display portion size wsy. For example, assuming that the first sentence of one or a plurality of sentences forming the summary sentence is equal to or less than the number of words that can be displayed in the current summary display unit size wsy, the process of the control unit 11 proceeds to step F504. move on. Then, the telop display time T1 is calculated by multiplying the sentence length Ls by a predetermined coefficient k.

Subsequently, in step F505, the control unit 11 starts counting of the internal timer, and displays the first sentence on the summary display unit 304 in step F506. At this time, the sentence length Ls is the summary display section size wsy
Because of the following, the entire first sentence is displayed on the summary display unit 304 as a telop. During this display operation, the control unit 11 monitors the time count value in step F507, and proceeds to step F515 when T1 is counted by the timer. Then, Step F5
In step F516, it is determined whether the display of the last sentence of the summary sentence has been completed.
, And the process returns to step F502.
Therefore, the second sentence of the sentences constituting the summary sentence is extracted next.

Subsequently, the control unit 11 makes a determination in step F503 for the second sentence. Here, if the sentence length of the second sentence exceeds the summary display unit size wsy (that is, the entire sentence at a time) Is not possible), the process of the control unit 11 proceeds to step F508, and multiplies the sentence length Lwsy, which can be displayed on the summary display unit, by a predetermined coefficient k to calculate the telop display time T1. Subsequently, in step F509, the control unit 11 starts counting of the internal timer, and in step F510, causes the summary display unit 304 to display the second sentence as a telop. However, at this time, since the sentence length Ls exceeds the summary display portion size wsy, only the displayable head portion is displayed. That is, a portion corresponding to the sentence length Lwsy from the beginning of the second sentence is displayed. During this display operation, the control unit 11 monitors the time count value in step F511, and when the time T1 is counted by the timer, the control unit 11 proceeds to step F512.
Proceed to.

In step F512, the displayed sentence is scrolled by one character. And step F31
At 3, wait for T2 time. Then, it is determined whether or not up to the last character of the second minute has been displayed in step F514,
If the last character has not been reached yet, step F51
Return to 2 and scroll one character. The T2 time as the standby time is a time that defines the scroll timing, which is also a value set in the system design. For example, if the time is about 0.5 to 1 second, the sentence is scrolled at an appropriate speed. Will go.

As a result of the processing in steps F508 to F514, for a sentence that cannot be displayed on the summary display unit 304, the display is scrolled one character at a time every T2 after the top is first displayed for T1. It will be displayed until the last character of the sentence.

When the last character of the sentence is displayed by scrolling, the process of the control unit 11 proceeds from step F514 to F515 to judge whether or not the display of the last sentence of the summary sentence is completed. If not, step F51
In step F50, after incrementing the variable n in 6,
Return to 2. Therefore, the third sentence among the sentences constituting the summary sentence is extracted next. Then, for the third sentence, steps F504 to 507 or step F
The telop display is executed by the processing of 508 to F514.

If it is determined in step F515 that the display of all the sentences constituting the summary sentence has been completed, the process proceeds to step F517 to display the head of the summary sentence.
That is, a state is displayed in which the displayable top portion is displayed in the summary display portion size wsy. In step F518, a scroll bar 307 described later is displayed, and the telop display process ends.

The display operation realized by the above telop display processing is as follows. For example, it is assumed that the digest creation button 306a is clicked in the browsing window 301 in which the digest display unit 304 is very narrow as shown in FIG. 26, and a digest is created. At this time, a summary sentence longer than the document length that can be displayed on the summary display unit 304 is created by the processing of FIG. 23 described above.

For example, it is assumed that the following summary sentence is generated for the text displayed on text display section 303 in FIG. "[Nice aging] / 8 cancer metastasis,
Can be suppressed! ? Characterizing cancer is cell proliferation and metastasis. Human cells have "oncogenes" and "cancer suppressor genes." In the elderly, normal regulation is lost over the years and non-braking mutations accumulate in cells, increasing the proportion of cells and leading to more cancers. Metastasis does not occur simply by increasing the number of cancer cells. Cancer cells dissolve proteins and so on, making a path and entering blood vessels and lymph vessels. From the aspect of cancer diagnosis and treatment (nm2
The expectations of 3) are gathering. "

Such a summary sentence is composed of the following seven sentences as follows. In the above-described telop display processing of the present example, telops are formed in units of sentences. [Nice aging] / 8 cancer metastasis can be suppressed! ? Characterizing cancer is cell proliferation and metastasis. Human cells have "oncogenes" and "cancer suppressor genes." In the elderly, normal regulation is lost over the years and non-braking mutations accumulate in cells, increasing the proportion of cells and leading to more cancers. Metastasis does not occur simply by increasing the number of cancer cells. Cancer cells dissolve proteins and so on, making a path and entering blood vessels and lymph vessels. Expectations of (nm23) have been gathered from the aspect of cancer diagnosis and treatment.

First, the first sentence is extracted by the processing of FIG. 25 and displayed on the summary display unit 304 as shown in FIG. The telop display states of the summary display unit 304 after the state of FIG. 25 will be described with reference to FIGS.

The sentence of FIG. 28 satisfies the sentence length Ls ≦ wsy (the entire sentence can be displayed).
In the processing of 504 to F507, the display state of FIG. 29A is continued for T1 time calculated according to the sentence length. Subsequently, since the sentence length also becomes the sentence length Ls ≦ wsy, the display of FIGS. 29B and 29C is executed by the processing of steps F504 to F507 for each T1 time calculated according to the sentence length.

Since the next sentence has a sentence length Ls> wsy (the entire sentence cannot be displayed), step F50 in FIG.
8 to F514 are performed. That is, first, FIG.
After the head of the sentence is displayed for the calculated T1 time as shown in FIG. 29, every T2 time, as shown in FIG. 29 (e) → (f),
The display scrolls one character at a time. Thereafter, the scrolling proceeds in the same manner, and the display of the sentence is completed when the state of FIG. 29G is reached.

Then, the sentences are sequentially extracted. Since these sentences satisfy the sentence length Ls ≦ wsy, respectively, in the processing of steps F504 to F507, the time T1 calculated according to the sentence length is shown in FIG. ) (I) and (j) are displayed.

As described above, each sentence is sequentially displayed as a telop, and when the sentence length is too long to be displayed, the portion that cannot be displayed is displayed by scrolling. Then, when the telop display of all the sentences constituting the summary sentence is completed, the head of the summary sentence is displayed as shown in FIG. 30 and the scroll bar 307 is displayed as steps F517 and F518 in FIG. That is,
After the entire summary is presented to the user by the above telop display, a scroll bar 307 is provided so that the user can scroll the characters on the summary display unit 304 arbitrarily and check the content of the summary. It is to be.

The creation and display of the summary sentence in this example are executed as described above, and this makes it possible to present a summary suitable for the user. First, the user displays the summary display 3
By setting the size of the summary 04 arbitrarily, the document length of the generated summary sentence can be set. In other words, when the user wants to view a detailed summary, he or she clicks the summary creation button 306a after widening the summary display section 304. On the other hand, when he wants to see a summary of simple content, he narrows the summary display section 304 and then clicks the summary creation button 306a. Just click. Thereby,
A summary of the size desired by the user is generated and displayed.

If the user makes the summary display portion 304 extremely long in the horizontal direction, a summary sentence having a minimum required document length is created regardless of the window size. It will be displayed as a telop. Therefore, for example, when the user
Even if the summary display section 304 is unavoidably made narrow (horizontally) in order to make the text wide, the user can view the summary sentence with appropriate contents in a readable state by making it into a telop. Thereby, the contents can be accurately recognized.

In the telop display process of this example, the summary sentence is converted into telops in units of sentences. Since the display time (T1) of one sentence is calculated according to the sentence length, each sentence ( Telop) is an appropriate display time for the user to read. Furthermore, when the sentence is long, it is preferable that the user recognizes one sentence in order to execute the scroll display (one sentence follows because the subsequent part is displayed in a moving manner instead of a switching display). Is easy for users to recognize).

In this example, the summary sentence is displayed in a normal fixed manner (all sentences are displayed collectively and fixedly) and a telop is displayed (moving or switching) according to the aspect ratio of the summary display section 304. However, such a method can be applied to the text. That is, when the text (part of the text) is displayed in the browsing window 301 or the above-described classification window 201, the aspect ratio of the display area is determined. Thus, an easy-to-read display can be realized.

[0209] 7. Other Display Processing Example I By the way, examples of the telop display processing executed in step F95 of FIG. 24 are not limited to the example of FIG. 25, and various processing examples can be considered. For example, instead of a sentence unit as shown in FIG. 25,
A telop may be formed in units of phrases, phrases, or the like, or the display may be divided according to the length of a sentence or phrase. It is also conceivable to scroll the entire summary from the beginning to the end. In any case, the entire summary may be presented to the user by switching display or moving display, or a combination thereof.

The setting of the display period, the switching timing, and the scroll timing as each telop can be variously considered. For example, as described above, in this example, the text and the summary can be read aloud, but the telop display timing can be set in accordance with the output timing of the read voice.

[0211] An example of such processing for adjusting to the reading timing will be described in detail as another example of the telop display processing. For example, in the reading process as described above,
Generate a reading file from the tag file, convert the reading file into a form suitable for a speech synthesis engine, and use the speech synthesis engine to speed up the natural feeling like talking to humans, paragraphs, sentences, Speaking is performed by separating phrases. Therefore, by setting such a paragraph, sentence, and phrase division, a telop division similar to the reading speed, and a display period, a telop display that is easy for the user to read can be realized. In other words, it is assumed that the reading speed of the text-to-speech engine is almost the same as the speed at which the user reads the displayed document, and the time required for the text-to-speech engine to read the text is not displayed at a constant speed. The displayed telops are sequentially switched or moved in accordance with the time required for reading.

As a specific example of the method, as described above, the reading process by the speech synthesis engine is executed (however, the output of the reading voice is not executed), and the CPU 13 refers to the reading timing and separates the telop display and the telop display. The switching timing may be set. For example, during the period when a certain phrase is being read out by the speech synthesis engine (actually no voice is output), a character string as the phrase is displayed as a telop, and when the read-out voice advances to the next phrase, Is switched to the telop display of the next phrase.

Hereinafter, the telop display processing in accordance with the reading timing will be specifically described. This process
It is assumed to be executed as the process of step F95 in FIG. 24 described above. That is, as the process of step F95,
This is a processing example different from that of FIG.

In this case, in the document processing apparatus 1, as shown in FIG. 32, a speech synthesis engine 40 that reads out a document or a summary and a telop creation engine 41 that creates a telop exchange necessary information while mutually exchanging information. Is performed, the telop is switched or displayed on the summary display unit 304 or the text display unit 303 according to the reading timing. Note that the telop creation engine 41 as well as the speech synthesis engine 40
It may be configured by hardware, or may be realized by software activated in the CPU 13. When the speech synthesis engine 40 and the telop creation engine 41 are realized by software, the application programs are stored in the ROM 15 or the hard disk 34 in advance. The controller 44 shown in FIG. 32 is configured by hardware or software, and serves as a part that controls the speech synthesis engine 40 and the telop creation engine. For example, when the speech synthesis engine 40 and the telop creation engine 41 are realized by software, the speech synthesis engine 40 and the telop creation engine 41
4 operates under the control.

By the way, in the case of such a telop display, the reading-out process by the speech synthesis engine 40 is a process for defining the telop timing, and there is no need to actually output the synthesized speech. For this reason, in FIG. 32, the output of the audio signal from the audio synthesis engine 40 can be turned off by the switch 42. That is, the switch 42 is turned on at the time of the above-described reading process, but is turned off at the time of performing the telop display process described below as step F95 in FIG. . The on / off of the switch 42 is performed by a control signal SY from the controller 44. The actual switch 42 may be configured by hardware, or the CP when the telop creation engine is started.
It may be realized by the algorithm of U13 (controller 44), and the form of the control signal SY differs depending on the specific configuration.

[0216] The telop output from the telop creation engine 41 is synthesized on the screen as the browsing window 301 and displayed on the display unit 30. Although not shown in the screen examples of the browsing window 301 shown in FIGS.
As the above user interface, an operation button that allows the user to variably set the reading speed may be prepared, and the user may set the reading speed by operating the mouse of the input unit 20. The reading speed in the processing described below is the speed of the telop display. The controller 44 executes the operation of the speech synthesis engine 40 in accordance with the set value of the reading speed input by the user, so that the telop display speed can be set as desired by the user.

As described above with reference to FIGS. 16 to 22, the document processing apparatus 1 converts the tag file into a reading file and, for example, assigns Mark = *
** is added to generate a shared file FL in a format suitable for the speech synthesis engine 40 and stored in the RAM 14 or the like. This shared file FL has a format that can be accessed from the telop creation engine 41, and the telop creation engine 4
1 is a format from which information can be read and / or written. Note that this example will be described as a telop display for a summary sentence. Therefore, the shared file FL is a read-out file formed from the tag file as the summary sentence generated in the process of FIG. This is a format suitable for the speech synthesis engine 40.

When executing the telop display, the speech synthesis engine 40 executes, for example, based on the shared file FL, for example.
As in the case of Mark = 10000 to Mark = 10001, the text-to-speech processing is performed for each phrase and a synthesized voice is output (however, switch 4
No sound is actually output because 2 is off). At this time, the telop creation engine 41 creates a telop in accordance with the operation of the speech synthesis engine 40, and outputs the created telop to the display unit 30.

That is, when starting the telop display, the speech synthesis engine 40 accesses the shared file FL and reads out information such as Mark = *** and a character string that constitute one phrase. Then, the speech synthesis engine 40 analyzes the input information and the character string, and supplies a control signal indicating two Mark = *** timings indicating the start position and the end position of the phrase to the telop creation engine 41. here,
The speech synthesis engine 40 supplies a control signal indicating the timing of Mark = n-1 and Mark = n to the telop creation engine 41.

Subsequently, the telop creation engine 41 creates, as a telop, a character string after Mark = n-1 indicating the phrase start position based on the control signal supplied from the speech synthesis engine 40, and displays the telop. Is supplied to the speech synthesis engine 40, and the display of the telop is started. Then, the speech synthesis engine 4
0 starts reading out the phrase based on the control signal supplied from the telop creation engine 41, accesses the shared file FL, reads out the information and the character string constituting the next phrase, analyzes the phrase, and analyzes the phrase. A control signal indicating the timing of Mark = n and Mark = n + 1 indicating the start position and the end position is supplied to the telop creation engine 41.

Subsequently, the telop creation engine 41 creates a character string after Mark = n as a telop based on the control signal supplied from the speech synthesis engine 40. The telop creation engine 41 supplies to the speech synthesis engine 40 a control signal indicating that the display of the telop is to be started when the speech equivalent time required for the speech synthesis engine 40 to read the previous phrase has elapsed. ,
Start displaying the character string after Mark = n as a telop. That is, the telop creation engine 41 switches and displays the character corresponding to Mark = n to a character string after Mark = n so that the character corresponding to Mark = n is positioned at the top of the summary display unit 304, for example, which has an extremely long horizontal shape. Alternatively, the character string after Mark = n is moved and displayed, and the character corresponding to Mark = n is displayed in the summary display unit 30.
4 at the beginning.

In order to explain the specific contents of the telop displayed on the summary display section 304, a description will be given with reference to FIG. Here, "abcdefghijk.
It is assumed that each alphabetic character of "." Represents one element such as a word to constitute a summary sentence of the document, and "ab
Mark = n-1, Mark at the beginning and end of cdefg ”
= n is given, and the description is made assuming that one phrase is constituted.

As shown in FIG. 33A, when “abcdefghijklmnop” is displayed as a telop in the telop display area 185, from Mark = n−1 to Mark = n
“Abcdefg” in the range up to is read out by the speech synthesis engine 40. And the speech synthesis engine 4
When reading by 0 reaches Mark = n, ie, "a
When the required time equivalent to the reading of "bcdefg" elapses,
As shown in FIG. 33B, the telop creation engine 41
To mark "hijklmnopqr.
.. ", and the voice synthesis engine 40 reads out" hijklmnopqr "in the range from Mark = n to Mark = n + 1.

[0224] Under the control of the controller 44, the document processing apparatus 1 synchronizes the speech synthesis engine 40 and the telop creation engine 41 in this manner, and intermittently displays the telop on the summary display unit 304.

Here, for example, FIG.
As shown in (a), from Mark = n-1 constituting one phrase
"Abcdefghijklm" which is a range up to Mark = n
Nopqr ”is displayed in the summary display section 304 at that time.
Consider the case where it does not fit. In such a case, when the next phrase is switched and displayed as described above in order to be displayed on the summary display unit 304, "qr", which is a portion that does not fit in the summary display unit 304, will not be displayed at all.
Therefore, the control unit 11 determines that one phrase is in the telop display area 18.
If not, this phrase is processed by the following two methods.

As a first method, as shown in FIG. 34B, “abc” which is in a range from Mark = n−1 to Mark = n.
defghijklmnopqr ”and a new Mark =
There is a method of adding n '. In this case, the control unit 11 assigns Mark = n 'as follows. First, the speech synthesis engine 40 analyzes “abcdefghijklmmnopqr”, which is in the range from Mark = n−1 to Mark = n, which has been read by accessing the shared file FL shown in FIG. 1. A control signal indicating the timing of Mark = n is supplied to the telop creation engine 41. Subsequently, the telop creation engine 41 includes the speech synthesis engine 4
Based on the control signal supplied from 0, Mark = n-1 to Ma
"abcdefghijklmn" which is a range up to rk = n
Then, the telop creation engine 41 accesses the shared file FL and assigns Mark = n 'to a position of a unit smaller than at least a phrase such as a word, for example. , Mark = n-1
Create the following character string as a telop. Then, the telop creation engine 41 supplies a control signal indicating that the processing of the shared file FL has been completed and the start of the display of the telop to the speech synthesis engine 40, and starts the display of the telop.

Subsequently, based on the control signal supplied from the telop creation engine 41, the speech synthesis engine 40 executes “abcd” in the range from Mark = n−1 to Mark = n ′.
efghjklm "
Access to the shared file FL to access Mark = n 'to Mark = n + 1
The information and the character string constituting “nopqr” in the range up to are read and analyzed, and a control signal indicating the timing of Mark = n ′ and Mark = n + 1 is supplied to the telop creation engine 41.

Subsequently, the telop creation engine 41 creates a character string after Mark = n 'as a telop based on the control signal supplied from the speech synthesis engine 40.
The telop creation engine 41 uses “abcd”, which ranges from Mark = n−1 to Mark = n ′ by the speech synthesis engine 40.
When the required reading time corresponding to the required time for reading out “efghjklm” has elapsed, a control signal indicating that the display of the telop is started is transmitted to the speech synthesis engine 4.
Supply 0. Then, the telop creation engine 41
As shown in FIG. 34C, Mark = n ′ is set so that the character corresponding to Mark = n ′ is positioned at the top of the summary display unit 304.
Switch to the following character string and display, or Mark = n '
The subsequent character string is moved and displayed, and the character corresponding to Mark = n 'is positioned at the head of the summary display unit 304.

[0229] Telop creation engine 41 (control unit 11)
In this manner, a new mark = *** is added to a position of a unit smaller than at least a phrase to divide one phrase, and the telop displayed on the summary display unit 304 has at least two Mark = By processing so as to include ***, all the character strings to be read can be displayed on the summary display unit 304 as a telop.

On the other hand, as a second method, FIG.
As shown in (1), there is a method of omitting an arbitrary element of “abcdefghijklmnopqr” in a range from Mark = n−1 to Mark = n. In this case, the control unit 11 omits arbitrary elements as follows.

First, the speech synthesis engine 40 first
Accessed and read the shared file FL shown in 2
"Abcdefg" which is in the range from Mark = n-1 to Mark = n
hijklmnopqr ”and Mark = n
A control signal indicating the timing of −1, Mark = n is supplied to the telop creation engine 41.

Subsequently, based on the control signal supplied from the speech synthesis engine 40, the telop creation engine 41 executes “abcde” in the range from Mark = n−1 to Mark = n.
fghjklmnopqr ”does not fit in the summary display unit 304. Then, the telop creation engine 41 accesses the shared file FL and sets Mark = n−1.
"Abcdefghijk, which is in the range from
lmnopqr ”is converted into a form of a verbal stop, or an optional element that forms a conjunction and / or a particle is removed, and a character string after Mark = n−1 is created as a telop.
Here, “abcdefghijklmnopqr”
Of these, two elements “i” and “r” are omitted. Then, the telop creation engine 41 supplies the speech synthesis engine 40 with a control signal indicating that the processing of the shared file FL has been completed and that the display of the telop is to be started, and starts the display of the telop.

Subsequently, the speech synthesis engine 40, based on the control signal supplied from the telop creation engine 41,
"Ab" which is in the range from omitted Mark = n-1 to Mark = n
start reading out cdefghjklmnopq ”and access the shared file FL from Mark = n
"Stuvwxyz ..." in the range up to Mark = n + 1
Read and analyze the information and character strings that make up Mark =
A control signal indicating the timing of n, Mark = n + 1 is supplied to the telop creation engine 41.

Next, the telop creation engine 41 creates a character string after Mark = n as a telop based on the control signal supplied from the speech synthesis engine 40. The telop creation engine 41 uses “abcdef”, which is a range from Mark = n−1 to Mark = n by the speech synthesis engine 40.
When the required reading time corresponding to the reading time of "ghjklmnopq" has elapsed, a control signal indicating that the display of the telop is started is supplied to the speech synthesis engine 40. Then, the telop creation engine 41
As shown in FIG. 35C, Mark = n is set so that the character corresponding to Mark = n is positioned at the top of the summary display unit 304.
The display is switched to a subsequent character string, or the character string after Mark = n is moved and displayed, and the character corresponding to Mark = n is positioned at the head of the summary display unit 304.

[0235] Telop creation engine 41 (control unit 11)
Is used to convert the target phrase into a descriptive expression, remove optional elements that form conjunctions and / or particles, and omit any of the elements that make up the phrase. Then, by processing the telop displayed on the summary display unit 304 so as to include at least two or more Mark = ***, all the character strings to be read are displayed in the telop display area 1.
85 can be displayed as a telop.

Note that the telop creation engine 41 (control unit 1)
1) Accessing the shared file FL, actually converting the target phrase into a descriptive expression, and removing the optional elements that constitute the conjunction and / or particle, etc., to construct the phrase. May be omitted, but a tag indicating that the shared file FL is to be converted into a descriptive expression and displayed or a tag indicating an element to be removed and displayed is added to the shared file FL. You may make it.

As described above, in the document processing apparatus 1, a telop is created by the telop creation engine 41 in conjunction with the reading by the speech synthesis engine 40, and the telop is switched or displayed on the summary display unit 304. Can be. Thus, the speech synthesis engine 4
0 and the telop creation engine 41 are operated in conjunction with each other to create a telop of a given document or a created summary with high accuracy and display the created telop at a timing that makes it easy for the user to grasp. Can be.

In the above description, when the telop is displayed, the output of the reading voice by the voice synthesis engine 40 is turned off. However, the reading voice may be output together with the telop display. . Furthermore, it has been described that the telop creation engine 41 determines whether or not all elements constituting the target phrase fit in the summary display unit 304, and performs processing and embedding if it does not fit. These determinations and processing may be performed by a functional unit other than the telop creation engine 41 and the telop creation engine 41.

Furthermore, in the above example, the telop creation engine 41 determines in real time whether or not all the elements constituting the target phrase fit in the summary display section 304. However, when the shared file FL is generated from the file for reading out, it is determined whether or not all the elements constituting each phrase fit in the summary display unit 304 for all the phrases. A processing may be performed in advance on a phrase that does not exist, and the shared file FL may be generated. In addition, all elements constituting the target phrase in the above processing example are displayed in the summary display unit 304.
If the processing does not fit into the phrase, there is a method of adding a new Mark = *** to at least the position of a unit smaller than the phrase to divide one phrase, and an optional element constituting one phrase May be combined with the method of omitting.

[0240] By the way, the description has been given as the telop display of the summary sentence displayed on the summary display unit 304. However, it is naturally possible to execute the above processing on the text displayed on the text display unit 303.

[0241] 8. Other Display Processing Example II Each of the above examples is based on the premise that the document is displayed horizontally, and when the display area of the summary display unit 304 or the like is extremely horizontal (when the aspect ratio is less than Rth), Instead of fixed display, telop display has been executed. However, as a display mode, it is conceivable that the document is displayed vertically, and in such a case, it is preferable to select the fixed display or the telop display according to the aspect ratio.

For example, FIGS. 36 and 37 show a text display unit 303 and a summary display unit 304 in the browsing window 301.
Indicates a case where vertical writing is displayed. In such a case as well, the processing shown in FIGS. 23 and 24 is possible, but in that case, the determination processing in step F82 in FIG. 23 is different. That is, in the above horizontal writing display, the processing is branched depending on whether the aspect ratio (vertical y / horizontal x) is equal to or more than a predetermined value Rth. In this case, the aspect ratio (horizontal x / vertical y) is set to a predetermined value. The process is branched depending on whether or not it is equal to or greater than Rth. That is, the case where the aspect ratio (horizontal x / vertical y) is equal to or more than the predetermined value is the case where the display area is recognized to some extent as a normal shape, while the aspect ratio (horizontal x / vertical y) is determined. The case where the display area is smaller than the predetermined value is a case where the display area is extremely vertically long.

Therefore, when the aspect ratio (horizontal x / vertical y) is equal to or more than the predetermined value, the process proceeds to step F83, and a summary sentence having a document length corresponding to the window size is generated. Perform fixed display. For example, FIG.
Is an example in which the summary is fixedly displayed. On the other hand, if the aspect ratio (horizontal x / vertical y) is less than the predetermined value, the process proceeds to step F84.
In step F95 in FIG. 24, a telop display is performed in step F95 while generating a summary sentence having a document length exceeding the window size. For example, as shown in FIG. 37, when the summary display unit 304 has an extremely long shape in the vertical direction, the summary text is displayed as a telop.
In the telop display method, the processing in FIG. 25 described above or the processing described in FIGS. 32 to 35 may be performed.

As described above, also in the case of the vertical writing display, the display that is easy for the user to see can be realized by executing the telop display according to the shape of the display area. Of course, the present invention can also be applied to the display of the text, and when the text display unit 303 is extremely vertically long, the text may be displayed.

The procedure as the document processing apparatus 1 of the present invention and the document processing method employed therein has been described as an embodiment. However, this is merely an example, and the configuration and processing examples of the document processing apparatus 1 are various. Can be considered. Specific examples of devices that constitute the document processing apparatus 1 are various. For example, when the input unit 20 in the document processing apparatus 1 is taken as an example, not only a keyboard and a mouse but also a tablet,
Other devices such as a light pen, a wireless commander device using infrared rays, and the like are conceivable.

In the above example, the document is described as being transmitted from the outside to the communication unit 22 via a telephone line or the like, but the present invention is not limited to this. For example, the present invention can be applied to a case where a document is transmitted via a satellite or the like. In addition, the document may be read from the recording medium 32 in the recording / reproducing unit 31 or may be written in the ROM 15 in advance.

Further, in the embodiment, an example of a method of tagging a document has been described, but it is needless to say that the present invention is not limited to this tagging method. Furthermore, in the above-described embodiment, Japanese and English sentences have been exemplified, but it goes without saying that the present invention is not limited to these languages. As described above, it goes without saying that the present invention can be appropriately changed without departing from the spirit of the present invention.

[0248] 9. Provision of Document Processing Program by Recording Medium 9-1 Recording Medium In the present invention, for example, a disk-shaped recording medium or a tape-shaped recording medium on which the above-described electronic document processing program is written, such as the recording medium 32 shown in FIG. Can be realized. The recording medium of the present invention can be similarly used as the HDD 34 shown in FIG.

According to such a recording medium 32,
A program for realizing the above-described document processing method can be provided. For example, using a general-purpose personal computer or the like, the document processing apparatus of the present invention, that is, the document processing apparatus that performs display processing according to the aspect ratio of the display area is provided. Can be easily realized. Of course, the recording medium 32 may be an optical disk, a magneto-optical disk, a magnetic tape, a memory card such as a flash memory, a memory chip, or the like, in addition to the floppy disk. Furthermore, the program for realizing the document processing method of the present invention can be provided also via a network communication such as the Internet. Therefore, the present invention can be applied to a program server or a recording medium in a communication process. Things.

Further, as a recording medium, a recording medium which records document data to be processed by the program together with the operation control program for realizing the above processing is also useful. For example, when the above-described document processing apparatus is realized using a personal computer, the summary display unit 3 is realized by adopting the window display form described above.
The size (aspect ratio) such as 04 can be arbitrarily changed. However, when a small-sized portable device is considered as a dedicated document processing device, the size of the display unit is limited.
4 or the like may be a fixed size. And
As a document processing apparatus having a fixed-size display unit, the display unit may be extremely horizontal with, for example, about one line, or may have a certain wide display area and sufficiently display a summary sentence or the like. Some devices have made it possible.

For such various document processing apparatuses,
By providing the operation control program at the same time as providing the electronic document data from the recording medium, a display form suitable for the document processing apparatus can be realized. For example, in a document processing apparatus having an extremely horizontally long display unit (in the case of horizontal writing display), a document is displayed in the form of a telop, while a document processing apparatus having a display unit having a display area with a certain enough area is used. , The document is fixedly displayed.
That is, since the operation control program is recorded together with the document data as the recording medium of the present invention, a display suitable for various document processing apparatuses can be realized.

9-2 Mobile Terminal Device and Document Processing System Configuration Various mobile terminal devices will be described as examples of the document processing device having the fixed-size display unit as described above. According to the present invention, an operation control program (document processing program) for executing a display process according to the aspect ratio of the display unit as described above is recorded on the recording medium, and the display unit displays the document processing program together with the document data. By providing the document processing device (for example, a portable terminal) having a fixed size, a document display suitable for a display unit of the document processing device can be performed.

An example of a portable terminal device (portable terminal 50) as an example of such a document processing device will be described with reference to FIG. 38 and thereafter. In this portable terminal device, a user uses the portable terminal device alone. In addition, the system can be connected to the document processing apparatus 1 as shown in FIG. 1 to perform a system operation.

Hereinafter, the portable terminal device (portable terminal 50)
And the operation of the portable terminal 50 and the document processing apparatus 1 as a document processing system will be described. First, an example of the appearance will be described with reference to FIGS.

FIGS. 38A and 38B show examples of the appearance of two types of portable terminals 50A and 50B.
50B are small and lightweight devices. On the upper surfaces of the portable terminals 50A and 50B, for example, display units 51A and 51B using a liquid crystal panel and a required number of operation units (operation keys) 52 are provided. Here, the display unit 51A of the mobile terminal 50A has a horizontally long shape in which the aspect ratio (vertical y / horizontal x) is less than the predetermined value Rth described in FIG. 23, for example, and can display a document of about one line. ing. On the other hand, the mobile terminal 5
The display unit 51B of 0B is an example in which the aspect ratio (vertical y / horizontal x) is equal to or more than a predetermined value Rth, and the display area is set wide so that a document of, for example, about 5 to 10 lines can be displayed. .

[0256] The number of operation keys and operation contents as the operation section 52 are set according to the functions provided in the portable terminals 50A and 50B. Here, for example, it is assumed that a feed / return operation for switching the display of various documents, an erasing operation for erasing unnecessary documents, and the like can be performed.

[0257] A reader terminal 53 is provided at a predetermined position such as a side surface of the portable terminals 50A and 50B, so that information can be transferred to and from the document processing apparatus 1 as shown in FIG. A disk slot 60 is formed at a predetermined position such as the front surface of the portable terminals 50A and 50B, and a recording medium 32 such as a floppy disk can be inserted therein.
In this example, the recording medium 32 is a floppy disk. However, a portable terminal corresponding to a memory card or a disk can be formed.

FIG. 39 shows the appearance of a personal computer 90, which is an example in which the document processing apparatus 1 of FIG. In this case, as is generally the configuration of the general-purpose personal computer 90, the personal computer main body includes:
Monitor display 91, keyboard 94, mouse 95
Etc. are connected. In addition, a floppy disk drive 93, a CD-ROM drive 92, and the like are provided in the main body of the personal computer. The monitor display 91 is provided on the display unit 30 shown in FIG. 1, the keyboard 94 and the mouse 95 are provided on the input unit 20 shown in FIG. 1, and the floppy disk drive 93 and the CD-ROM drive 92 are provided on the recording / reproducing unit 31 shown in FIG.
, Respectively. Although not shown in FIG. 39, the configurations of the communication unit 21, the main body 10, the audio output unit 33, and the HDD 34 of FIG. 1 are also provided in the personal computer main body.

FIG. 39 shows a portable terminal reader 96 as a separate device connected to the personal computer main body. The portable terminal 50 (50A or 50B) in FIG. 38 can be attached to the portable terminal reader 96,
At this time, by connecting the reader terminal 53, data communication between the personal computer main body (that is, the document processing apparatus 1) and the portable terminal 50 becomes possible. For example, the control unit 11 shown in FIG.
0 can receive document data.

FIG. 39 shows an example of a hardware configuration for realizing the document processing system. Of course, various other examples are conceivable. First, as the document processing apparatus 1, a dedicated document processing apparatus having the configuration shown in FIG. 1 may be formed without using a general-purpose personal computer. Moreover,
Needless to say, a portable notebook personal computer may be used instead of the desktop personal computer shown in FIG. Further, the portable terminal reader 96 may be built in a personal computer main body (or a device as a dedicated document processing device). Further, the data transfer between the portable terminal 50 and the document processing apparatus 1 may be performed wirelessly by, for example, infrared transmission or the like, in addition to being performed by wire using the portable terminal reader 96 or the like.

FIG. 40 shows the configuration of the portable terminal 50. The mobile terminal 50 includes a control unit 54, a document memory 55, a receiving unit 56, a display drive 57, an interface 58, and a recording / reproducing unit 61 in addition to the display unit 51, the operation unit 52, and the reader terminal 53 described above. The control unit 54 includes a CPU, a ROM,
The microcomputer is provided with a RAM and performs various operation processes.

The receiving section 56 is a section that can receive document data from a wireless telephone line or the like. The received document data is transferred to the control unit 54 and processed. This receiving unit 56
For example, it has a receiving function similar to that of a so-called pager (registered trademark). The document memory 55 stores the document data received according to the instruction of the control unit 54,
This is a part for storing the summary sentence and the like generated in. The display drive 57 causes the display unit 51 to execute a display operation based on an instruction from the control unit 54. The control unit 54 displays the summary sentence stored in the document memory 55 on the display drive 5
7 can be displayed on the display unit 51.

The interface 58 includes a reader terminal 53
And the portable terminal reader 22 and the interface 12 of FIG.
Is a part that performs processing for transferring data to the control unit 11 of the document processing apparatus 1 via the. The data to be transferred is document data stored in the document memory 55.

The recording / reproducing section 32 can perform a recording / reproducing operation on the recording medium (floppy disk) 32 inserted from the disk slot 60 described above. If the document data is recorded on the recording medium 32,
The document data can be read from the recording / reproducing unit 32 and stored in the document memory 55 through the processing of the control unit 54. Further, since the document processing program is recorded on the recording medium 32, the control unit 54 can read the document processing program from the recording / reproducing unit 32 and perform an operation process based on the document processing program. The receiving unit 56 is assumed to receive the document data. However, when the document processing program is transmitted together with the document data from the communication server, the control unit 54 fetches the document processing program and adds the document processing program to the document processing program. It is possible to perform operation processing based on the above. That is, both the receiving unit 56 and the recording / reproducing unit 61 function as a means for obtaining the document data and the document processing program.

9-3 Document and Program Import Process by Portable Terminal Device The process of the control unit 54 when the portable terminal 50 imports document data and a document processing program (the control unit 54 of the portable terminal 50A or the control unit of the portable terminal 50B). 54 processing)
Will be described with reference to FIG. When one or a plurality of document data and a document processing program are transmitted from a predetermined server, or when the recording medium 32 on which the one or a plurality of document data and the document processing program are recorded is loaded, the control unit 54 executes the step In step F300, the document data is loaded into the internal RAM from the receiving unit 56 or the recording / reproducing unit 61, and the received document data text is stored in the document memory 55. Further, the document processing program is loaded into the internal RAM.

[0266] Various examples can be considered as the form of reception by the receiving section 56. For example, it is conceivable that the server organization transmits document data to the portable terminal 50 at an arbitrary time. In this case, for example, the user who owns the mobile terminal 50 registers in advance with the server organization. As a result, the server organization makes a call to the portable terminal 50 of the user at an arbitrary point in time, and transmits the document data according to the line connection. Alternatively, the receiving unit 56 may be provided with a transmission function, and the user may connect the line to the server and request information transmission, so that document data is transmitted from the server. Furthermore, by connecting the mobile terminal 50 to a mobile phone or a public phone,
It is also conceivable to allow a user to request the server to send document data.

After fetching the document data (text) and the document processing program received or read from the recording medium, the control unit 54 starts the document processing program in step F301, and summarizes the document data in step F302. Create The word processing program is
This is a program for executing a summary creation process, a summary display process, and the like, which are executed by the above-described document processing apparatus 1.

The summary sentence creation processing in step F302 is executed by the processing in FIG. 23 similarly to the document processing apparatus 1 described above. However, in the case of the portable terminal 50, the display unit 51
Display area is fixed. And the mobile terminal 5
Considering various types of mobile terminals such as 0A and 50B, various types of display units 51 (51A and 51B) can be considered as the aspect ratio.

Therefore, the control unit 54 performs the processing of FIG. 23 according to the document processing program. For example, in the portable terminal 50A, the aspect ratio of the display unit 51A is less than the predetermined value Rth. The summary creation processing to be performed is always performed in steps F81 → F82 → F in FIG.
84 → F85 →... (The imported document processing program is step F83
The process of step F83 is not performed in the portable terminal 50A. That is, in the portable terminal 50A, a summary sentence having a document length exceeding the display area of the display unit 51A for the purpose of displaying the telop of the summary sentence is created based on the document processing program.

On the other hand, in the portable terminal 50B, since the aspect ratio of the display unit 51B is equal to or greater than the predetermined value Rth, the summary creation processing performed by the portable terminal 50B always includes steps F81 → F82 → F83 → F85 → The algorithm proceeds as follows. (The imported document processing program also includes the process of step F84, but the process of step F84 is not performed in the portable terminal 50B.) That is, the portable terminal 50B uses the portable terminal 50.
Based on the same document processing program as that loaded into A, a summary sentence having a document length of a size corresponding to the display area of the display unit 51B is created for the purpose of fixed display of the summary sentence.

When the controller 54 creates a summary for each of the received one or a plurality of documents, the controller 54 proceeds to step F3.
At 03, the digest is stored in the document memory 55, and a series of processes at the time of reception is completed.

By such processing, the document memory 55 stores, for example, the text and the summary of each document as shown in FIG. For example, as shown in the figure, a document number is assigned to each of the documents, and the text of the document (A document, B document,...) And a summary of the document corresponding to each text (A summary, B summary,...) Is stored.

9-4 Summary Display Process by Portable Terminal Device The portable terminal 50 (50A, 50B) stores the text and summary sentence of the received document data in the document memory 55 as described above. At any time, the summary text of each document is displayed on the display unit 51 (51A, 51B), and the content of each document can be confirmed. In particular, at that time, in the case of the portable terminal 50A, the summary is converted into a telop and displayed by switching or moving display.
A summary of the document can be displayed in a state where A is suitable for being horizontally long. In the case of the portable terminal 50B, the summary of the document length corresponding to the size of the display unit 51B is fixedly displayed, so that the summary of the document can be displayed in a state suitable for the display unit 51B.

In the portable terminal 50 (50A, 50B), it is possible to delete a document that the user considers unnecessary. As will be described later, when the user checks the document content and wants to know the content in more detail (that is, wants to read not only the summary but also the text), the document data is transferred from the portable terminal 50 to the document processing apparatus 1. By doing so, it is possible to browse the text.

The processing of the control unit 54 for presenting a summary of each document stored in the document memory 55 to the user is shown in FIG.
It looks like 2. As the user operation for presentation, an operation for instructing presentation start and presentation of the next document, an operation for instructing presentation of the previous document, and an operation for instructing erasure can be performed using the operation keys of the operation unit 52. And

When the user performs an operation for requesting the start of the presentation of the summary sentence, the process of the control unit 54 proceeds to step F40 in FIG.
From 0, the process proceeds to F401, and the document processing program loaded as described above is started. And thereafter, the control unit 5
4 performs display processing based on the document processing program.
First, the process proceeds to step F402, where a variable n referring to the document number is set to “1”.

Then, the control unit 54 makes a decision at step F403.
As shown in FIG. 43, out of the document data stored in the document memory 55, the summary of the document number (n) is read, sent to the display drive 57, and displayed on the display unit 51. Therefore, the "A summary" of FIG. 36 is first displayed. However, this display operation is executed by the same processing as in FIG. 24 described above based on the document processing program.

Although the summary sentence creation in step F302 in FIG. 41 has been described in the same manner as in FIG. 23, the flag Ft is turned on (“1”) or off (“0”) in step F83 or F84 in FIG. Have been. Specifically, in the case of the portable terminal 50A, the flag Ft is always "1", while in the case of the portable terminal 50B, the flag Ft is always "0". Therefore, the control unit 5 based on the document processing program
The display process of step F403 of FIG. 42 executed by the control unit 4 is the control unit 54 of the mobile terminal 50A.
The summary sentence is converted into a telop and displayed (FIG. 24).
Step F95 is executed).
In the case of the control unit 54B, the process is a process of fixedly displaying the summary sentence (Step F96 in FIG. 24 is executed). As a result, the display unit 51 of each portable terminal 50 is displayed.
In this case, an appropriate display operation is realized according to the aspect ratio.

During a period in which a fixed summary text or a telop is displayed, the control unit 54 sets the step F404,
The user's operation is monitored in F405 and F406.
In the case of the mobile terminal 50A, step F40
The telop display started in step 3 is fixed to the state where the first sentence is displayed when the display of the entire sentence of the summary sentence is completed, but even if the telop display is still being performed,
If a user operation is detected in any of steps F404, F405, and F406, the process ends.

If the user has performed an operation to request the presentation of the next document, the process of the control unit 54 proceeds from step F404 to F407, increments the variable n, and returns to step F403. In this step F403, the summary sentence of the document number (n), that is, in this case, the control unit 54 performs fixed display processing or telop display processing of the summary sentence of the document stored in the document memory 55 as the next document number. become.

If the user performs an operation for requesting the presentation of the previous document, the process of the control unit 54 proceeds to step F405.
The process proceeds to F408, decrements the variable n, and returns to step F403. In this step F403, the summary sentence of the document number (n), that is, in this case, the control unit 54 fixes the summary sentence of the document stored in the document memory 55 as the document number before the document that has been displayed until then. Display or telop display processing is performed.

By the processing according to the operation for obtaining the next document and the previous document, the user can arbitrarily confirm the summary sentence of each received and stored document on the display. .

Although omitted in the processing flow of FIG. 42, if the user performs an operation for obtaining the previous document in a state where n = 1, that is, a state in which the summary text of document number 1 is displayed, What is necessary is just to invalidate the operation. Similarly,
When the user performs an operation for obtaining the next document in a state where the summary of the last document is displayed as the document number, the operation may be invalidated. However, when the user performs an operation for obtaining the previous document while the summary text of document number 1 is displayed, the summary text of the last document number is displayed or the summary text of the last document is displayed. When the user performs an operation for obtaining the next document in a state where is displayed, the summary sentence of the first document number may be displayed.

In this example, when a user reads a summary sentence while a certain summary sentence is displayed and considers that the document data is unnecessary, an erasing operation may be performed. When the erasing operation is performed, the process of the control unit 54 proceeds to step F406.
Then, the process proceeds to F409, and the main body and the summary of the document data are deleted on the document memory 55. The document number is updated in accordance with the deletion. For example, if the user performs an erasing operation while the B summary in FIG. 43A is displayed, the control unit 54 deletes the B document and the B summary data from the document memory 55 in step F409, and furthermore, By advancing the subsequent document number, for example, FIG.
The state is as shown in FIG. That is, in response to the deletion of the body text and the summary sentence of the document number “2” as the B document, the C document and the D document are respectively changed to the document numbers “2” and “3”.
Move on. Then, the processing of the control unit 54 is step F4.
Since the process returns to 03 (the variable n remains unchanged), the C summary of the next C document is displayed with the deletion of the B document.

By the processing of FIG. 42 as described above, the user can confirm the contents of the received document by its summary. In particular, when the display unit 51A is the horizontally long mobile terminal 50A, the content is confirmed by displaying the summary text in detail by displaying the telop on the display unit 51A. Therefore, even if the portable terminal 50A cannot display a sufficient document length on the display unit 51A at one time, the user can accurately grasp the contents of the document. On the other hand, a mobile terminal 50B having a display portion 51B that is relatively wide and not in an extremely long horizontal shape
In the case of, the content of the document can be confirmed by fixed display on the display unit 51B. That is, since a relatively detailed summary is presented in a fixed display, the user can accurately grasp the contents of the document.

A user who uses these portable terminals 50A and 50B can easily delete documents determined to be unnecessary after grasping the contents of the documents. Also, for documents that you need (not erased)
The text will later be input by the user to this portable terminal 50 (50
A, 50B) is connected to the document processing apparatus 1 by the system as shown in FIG.

In the processing described with reference to FIGS. 42 and 43, it is assumed that the user can delete from the document memory 55 the document data determined to be unnecessary by viewing the summary. A processing method of selecting whether or not to transfer to the processing device 1 is also conceivable.

For example, as the process at the time of importing in FIG. 41, the control unit 54 stores the text and the summary of the received document in the document memory 55.
When the transfer flag is stored as shown in FIG.
It is set to 0 and stored. At the time of the display processing as shown in FIG. 42, the user's operations include the operation of instructing the start of presentation and the presentation of the next document, the operation of instructing the presentation of the previous document, and the transfer document It is assumed that the operation specified as “?” Can be performed.

The fixed display or the telop display of the summary sentence of each document is the same as that shown in FIG. 42. However, when checking each summary, the user finds a document (summary sentence) whose contents are desired to be understood in more detail. Then, while the summary is being displayed, an operation of designating the document as a transfer document is performed. In response, the control unit 54 sets the transfer flag of the document in the document memory 55 to “1”. For example, FIG. 44B shows an example in which the user designates a B document and a C document as transfer documents. In this way, a processing method in which a document important to the user can be designated, but a document determined to be unimportant is not deleted at that time but is left behind.

In this case, the user selects an important document. However, in the initial state, all the transfer flags are set to “1”, and the user performs an unnecessary designation operation to transfer the document. The processing may be such that the flag is set to “0”.

Furthermore, it is conceivable to combine the methods described with reference to FIGS. 43 and 44. For example, the user can perform an erasing operation and a transfer designation operation, and can select three states of an erasure operation, a transfer designation operation, or no operation while viewing each summary sentence. If there is an erasing operation, erasing is performed as in the example of FIG.
When a transfer designation operation is performed, a transfer flag is set as shown in FIG. If these operations have not been performed, the transfer flag is set to “0” as a hold, but is not erased. Of course, other than this, various display methods and selection operation methods can be considered.

9-5 Operation of Document Processing System The reception and display of document data and selection of important documents in the portable terminal 50 are performed as described above, but the user uses the document processing apparatus 1 for important documents. You can read the text. As shown in FIG.
By attaching “0” to the portable terminal reader 96, the control unit 11 of the document processing device 1 can read the document data stored in the document memory 55 of the portable terminal 50. In this case, the control unit 11 of the document processing apparatus 1 and the portable terminal 5
0 communicate with each other, and the document memory 55
The document data is transferred. For example, a configuration in which the control unit 11 can directly access the document memory 55 may be adopted.

In the case of the example shown in FIG. 43, the transferred document data is the body data of all the documents which have not been deleted in the state as shown in FIG. 43 (b). In the case of the example of FIG. 44, the control unit 54 extracts a document having the transfer flag = 1 as shown in FIG. 44B and transfers the document to the control unit 11 side. The data to be transferred may be only the text or both the text and the summary. It is also conceivable to transfer the document processing program to the document processing device 1. In this case, the portable terminal 50 functions as a supply source of the document data and the document processing program together with the communication unit 21 and the recording / reproducing unit 31 shown in FIG.

As described above, one or a plurality of documents are transferred. In the document processing apparatus 1, the above-described various processes can be performed on the transferred document (text). That is, the control unit 11 performs classification processing on the transferred document data into a classification model, summarizing processing according to the window size, reading-out processing of the text or the summary sentence, and the aspect ratio of the summarizing display unit 403. The fixed display or the telop display of the summary sentence can be executed.

Thus, the user can read the detailed contents of the text, hear the read-aloud voice, and easily refer to the selected document at a later time because the selected document is properly classified. You can do it. Of course, the document data can be effectively used by using various further functions of the document processing apparatus 1 (personal computer 90). From these facts, in the document processing system of this example, the acquisition, the content confirmation, and the selection of the document data can always be easily and accurately executed by the portable terminal 50.
Further, a required document can be processed in a high-level and various manners by a document processing apparatus, so that the system is very useful for a user.

As described above, the document data and the document processing program are supplied by the recording medium 32 or communication (the recording medium on the communication server side), whereby the display unit has a fixed-size document processing apparatus (for example, the portable terminal 50A, 50B or the like). In the description above, the example in which the telop display / fixed display is selected according to the aspect ratio of the display unit has been described. However, the document processing apparatus having a fixed display unit is not limited to the portable terminals 50A and 50B described above. Needless to say, there are many possibilities. Of course, the present invention is not limited to portable devices. For example, even in a document processing apparatus realized by a stationary personal computer, the display area of the summary text may be fixed.

Also, various configurations and processing examples of the portable terminal 50 as the document processing device can be considered. For example, it is conceivable that the portable terminal 50 can display not only the summary text but also the text, or the portable terminal 50 has a reading function. Further, the shape of the portable terminal 50 is not limited to the example of FIG.

[0298]

As will be understood from the above description, the present invention has the following effects. That is, according to the document processing apparatus and the document processing method of the present invention, the electronic document data is fixedly displayed according to the aspect ratio of the document display area, or switching display or moving display is performed for each part such as a telop display. Is set, and the display in the document display area is executed. Therefore, when a horizontally written document is displayed, for example, when the document display area is extremely horizontally long, the text is displayed in a switching display or a moving display, thereby realizing a document presentation that is easy for the user to see (read). be able to.
In the case of displaying a vertically written document, on the contrary, when the document display area is extremely vertically long, switching display or moving display is performed so that a document display that is easy for the user to see (read) can be obtained. it can. As described above, regardless of the state of the summary display area, the user can easily read the contents of the document data.

The aspect ratio of the document display area can be arbitrarily changed by providing an aspect ratio variable means capable of changing the aspect ratio of the document display area. The user can arbitrarily set the document display area by selecting the fixed display, the moving display, or the switching display as described above, and the display is easily understood accordingly. Conversely, when the user wants to display a telop, the user only has to operate the aspect ratio.

Further, in particular, there is provided a summary creating means capable of creating electronic document data as a summary from the electronic document data as the document body, according to the aspect ratio of the summary display area in which the summary is displayed. By selectively setting the fixed display, or the switching display or the moving display for each part, the display form of the summary is suitable. In addition, the summary creating means creates a summary sentence having a document length corresponding to a document length that can be displayed in the summary sentence display area, according to an aspect ratio of the summary sentence display area determined by the aspect ratio determining means, The user selects whether to create a summary sentence having a document length exceeding the document length that can be displayed in the summary sentence display area, and creates a summary sentence. This may be a document length that cannot be completely displayed in the summary display area when it is displayed as a telop as a moving or switching display. Therefore, in this case, the summary is not limited to the summary display area and has a sufficient document length. By creating a sentence and presenting it to the user, it means that an appropriate summary sentence for understanding the contents of the document can be presented.

Further, according to the recording medium of the present invention, it is possible to provide a program for realizing the document processing method of the present invention. For example, the document processing apparatus of the present invention can be easily realized using a general-purpose personal computer or the like. Become like Thus, the general user can easily enjoy the above effect. In addition, when electronic document data to be processed by the operation control program is recorded together with the operation control program, not only providing the document data to the document processing apparatus, but also having the above-described effects. Thus, a document processing operation as a display according to the aspect ratio of the display area can be realized. Further, by providing the operation control program on a recording medium, either fixed display or telop display is realized according to the aspect ratio of the display area in the received document processing device, and the display of the document processing device is performed. There is an effect that a display suitable for the section is performed.
