Abstract

PROBLEM TO BE SOLVED: To keep the consistency of an already read part and a part to be read from then and to prevent a user from feeling inconvenient in the case of reading a long document with interruption by preparing and storing the summary of the document to a specified part in the presented document and presenting the stored summary to the specified part at the time of presenting the document. SOLUTION: A bookmark information input part 2 inputs bookmark information (the position information of the specified part, a byte number from the head of the document to the specified part for instance) by specifying a desired part in the document displayed at a display part 1. A document summary part 4 prepares the summary to the specified part of the document (text data) based on the bookmark information when the bookmark information is inputted by specifying the prescribed part in the document displayed at the display part 1 from the bookmark information input part 2. At the time, a summary language dictionary 5 is referred to and the summary is prepared from document data stored in a storage part 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information presenting method for presenting an electronic document to a user and an information presenting apparatus such as an electronic book using the method.

[0002]

2. Description of the Related Art In recent years, the digitization of documents has progressed, and the practical use of online document browsing systems and electronic books has led to the reading and displaying of documents on the display of small information processing terminals instead of printed matter such as books. Is spreading. If documents are stored electronically and displayed electronically, high integration of information and high searchability can be realized, and thus the usage of such documents is expected to become more and more important in the future.

[0003] However, the conventional method of presenting an electronic document lacks special consideration for a case where a long document is read by a user. For example, unlike turning pages of a book,
When a user scrolls a long document endlessly on a display screen, a heavy load is imposed on the user's eyes. Due to such an interface problem that only a part of a long document can be displayed on a screen of limited size at present, few users actually read long sentences on a display screen on a daily basis. . Also, when using such an electronic display method, especially when reading a long document in several steps, the user may forget the contents read up to the previous time, This is often inconvenient for the user, because the user does not understand the position of the character in the form and the connection with the part to be read. Therefore, a system has been realized that allows a user to electronically mark a specific location in a document as a bookmark and access the location at a later date. However, the above-described problem is still solved. It has not been.

[0004]

SUMMARY OF THE INVENTION In view of the above problems, the present invention can maintain consistency between a read portion and a portion to be read when a document is presented electronically (ie, By presenting a summary of the already read portion of the document, the user can recall the content of the already read portion and understand the points, and at the same time, in the entire document of the content read so far, Position, and the connection with the part to be read in the future), especially when presenting information without interrupting the user when reading a long document while interrupting it many times. It is an object of the present invention to provide a method and an information presentation device using the same.

[0005]

(1) According to the information presenting method of the present invention, a summary of a document up to a designated portion in a presented document is created and stored in a storage unit, and the document is presented. In doing so, by presenting the summary stored in the storage means up to the designated portion, by presenting the summary to the part which the user has already read, by presenting the summary, It is possible to maintain consistency with the part to be read, and in particular, the user does not feel inconvenience even when reading a long document while interrupting it many times.
In other words, by presenting a summary of the already read portion of the document, the user can recall the contents of the already read portion and understand the points, It is possible to clearly grasp the position in the inside and the connection with the part to be read in the future.

Further, the length of the digest is determined based on at least one of the data amount up to the designated portion in the document and the presentation time of the document, so that the amount of the document that has been read and the perusal By increasing the degree of compression of the summary depending on the degree, for example, as the reading progresses, it is possible to avoid a situation where the summary part becomes longer and cumbersome.

[0007] Further, by creating the summary based on a designated character string in the presented document, it is possible to create the summary according to interest, understanding, importance, etc., which differ for each user. By presenting such a summary, it is easier to understand the read portion in the document.

(2) An information presenting apparatus of the present invention is an information presenting apparatus for presenting information such as a document, and a summary creating means for creating a summary of the document up to a designated portion in the presented document, and the summary Storage means for storing the summary created by the creation means, and a presentation means for presenting the summary stored in the storage means up to the specified location when presenting the document, The read portion and the portion to be read can be kept consistent. In particular, even when a long document is read while being interrupted many times, the user is not inconvenienced. In other words, by presenting a summary of the already read portion of the document, the user can recall the contents of the already read portion and understand the points, It is possible to clearly grasp the position in the inside and the connection with the part to be read in the future.

Further, the length of the summary is determined based on at least one of the data amount up to the designated portion in the document and the presentation time of the document, so that the amount of the read document and the perusal of the document are read. By increasing the degree of compression of the summary depending on the degree, for example, as the reading progresses, it is possible to avoid a situation where the summary part becomes longer and cumbersome.

The summary is created based on a designated character string in the presented document, so that the summary is created according to interest, understanding, importance, etc., which differ for each user. By presenting such a summary, it is easier to understand the read portion in the document.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. (First Embodiment) FIG. 1 shows an example of a configuration of a main part of a portable small information presenting apparatus such as an electronic book using the information presenting method of the present invention.

In FIG. 1, an operation unit 6 is composed of a keyboard, a touch panel, a pointing device such as a mouse, etc., and is used for inputting various instructions. The display unit 1 includes a display screen, such as a liquid crystal display, on which text and images can be displayed.

For example, document data (image data, audio data, text data, etc.) read from a recording medium, such as a CD-ROM, in a predetermined data amount unit by an information reading unit 7 composed of, for example, a CD-ROM drive. Are temporarily stored in the storage unit 3. The document data (text data) stored in the storage unit 3 is displayed on the display unit 1 in response to a user instruction input from the operation unit 6. Hereinafter, the description will be made assuming that the processing target in the present invention is only text data of the document data. Therefore, in the following description, a document means text data.

The bookmark information input unit 2 is composed of a keyboard, a touch panel, a pointing device such as a mouse, etc., and designates a desired location in the document displayed on the display unit 1 to thereby provide bookmark information (position of the designated location). Information is used to input, for example, the number of bytes from the head of the document to the specified location. The bookmark information input unit 2 does not need to be provided separately from the operation unit 6.
And the bookmark information may be input from the operation unit 6.

The document summarizing section 4 designates a predetermined portion in the document displayed on the display section 1 from the bookmark information input section 2 and, when bookmark information is input, based on the bookmark information, A summary up to a specified portion of (text data) is created. At this time, an abstract is created from the document data stored in the storage unit 3 with reference to the abstract language dictionary 5. Here, the summary refers to an excerpt of a part of the original text of the document or a text obtained by processing the original text to reduce the overall length. Keywords and the like suitable for the summary sentence are registered in the summary language dictionary 5 in advance. The document summarizing unit 4 searches the document data stored in the storage unit 3 for a keyword registered in the summary language dictionary 5, extracts a sentence including the searched keyword, and extracts the extracted sentence. They may be collected and summarized.

FIG. 2 is a flowchart for explaining the overall processing operation of the information presentation apparatus of FIG. When the user attempts to read a document recorded on a predetermined recording medium (for example, a CD-ROM), the user sets the recording medium on the information reading unit 7 and inputs a predetermined instruction from the operation unit 6, The document data is read from the recording medium, and a desired document is displayed on the display screen of the display unit 1 via the storage unit 3. The user reads the document while turning pages, for example, by operating a scroll key or the like provided in the operation unit 1. When you stop reading in this state,
In the document displayed on the display screen from the bookmark information input unit 2, the position of the place where reading has been completed is specified (for example, a part of the displayed document is specified through an input device such as a mouse or a touch panel). At that time, for example, as shown in FIG. 4, a bookmark mark 13 indicating the designated portion may be displayed. At this time, the bookmark information input unit 2 inputs, for example, the number of bytes from the head of the document to the specified location as bookmark information (step S1). this is,
Since this corresponds to sandwiching a bookmark in a book, input of the bookmark information as described above may be referred to as designation of a bookmark position. The input of the bookmark information is a known technique in, for example, word processing software.

When bookmark information is input from the user, the bookmark information input unit 2 notifies the bookmark information input to the document summarizing unit 4 and instructs creation of an abstract (step S).
2). In response to this instruction, the document summarizing unit 4 reads out the document data from the storage unit 3 (steps S3 to S3).
4), a summary is created from the beginning of the document to the location indicated by the bookmark information (that is, up to the location where the user has finished reading), and the bookmark information and the created summary are stored in the storage unit 3 ( Steps S5 to S6). When the user again displays the same document on the display unit 1 at a later date, a summary is displayed up to the point where the user has read the previous document, and thereafter, the original text of the document is presented.

The document summarizing method in the document summarizing section 4 may be a known one, and is not particularly limited. For example,
The method described in JP-A-7-182373 may be used.

FIG. 3 is a flowchart for explaining the processing operation of the display unit 1. To read a document recorded on a predetermined recording medium (for example, a CD-ROM), the user sets the recording medium on the information reading unit 7 and
, The document data is read from the recording medium and temporarily stored in the storage unit 3. Thereafter, or when trying to read the half-read document again (since the information relating to the document is already stored in the storage unit 3), the display unit 1 reads out all the information relating to the document from the storage unit 3 (step S1). S11).

Here, the information on the document includes the document data itself (original text) read from the recording medium, the abstract,
Say bookmark information. In the information read from the storage unit 3,
If the bookmark information is not included, the document is considered to be the first document read by the user, and the original text of the document is displayed from the beginning (step S12, step S1).
5).

When the information read from the storage unit 3 includes the bookmark information previously input by the user, for example,
As shown in FIG. 5, on the display screen of the display unit 1, a summary from the beginning of the document to the position of the bookmark, which is also read from the storage unit 3, is displayed. Display the original text (Step S13 to Step S1)
4).

Thus, the user can look at the summary of the part that he / she has already read, and then proceed with the remaining part with a feeling like “summary up to the previous time”. When the user inputs the bookmark information, the document summarizing unit 4 immediately starts the summarizing process in the background (while displaying the document on the display unit 1). The summary can be displayed without feeling time.

FIG. 4 shows an example of a screen display when bookmark information is input by the user in a document displayed on the display screen of the display unit 1. In FIG. 4, each line of the horizontally displayed document is represented by a rectangle. When bookmark information is input by the user, that is, when a desired location is designated in the document, a bookmark mark 13 indicating the designated location may be displayed at that location as shown in FIG. desirable. For example, a document before the bookmark mark 13 is a part that the user has already read, and a document after the bookmark mark 13 is a part that the user has not read yet.

At a later date, in order to read the document again,
When a document is displayed on the display unit 1, for example, a display screen as shown in FIG. 5 is obtained. That is, in the example of the display screen shown in FIG. 5, a summary of the part read up to the previous time (the part indicated by the bookmark information from the beginning of the document (bookmark mark 13)) is added before the part that has not been read yet. Is presented. In FIG. 5, the hatched portion represents the summary.

In the above description, the case where the summary from the beginning of the document to the designated portion, that is, the summary of the entire part read so far is presented, is described. A summary of a desired portion of the document may be presented. For example,
If the user is allowed to specify two bookmark positions, only the document portion between the specified positions (bookmark positions) can be targeted for summarization.

Further, in the above description, a case has been described in which a summary is created using only the latest bookmark information. To create a summary. For example, it is assumed that the user A specifies the position of the bookmark in the 50th sentence when reading the document for the first time, and specifies the bookmark position in the 500th sentence when reading the continuation for the second time. On the other hand, it is assumed that the user B specifies the position of the bookmark in the 400th sentence for the first time and the 500th sentence in the second time. In this case, if you only use the latest bookmark location information,
When reading the document for the third time, the user A and the user B will be presented with the same range of summaries (from the beginning of the document to the 500th sentence). Here, using the bookmark information in the past, for example, for the user A, the 50th sentence to the 500th sentence
Up to the first sentence is the subject of summarization.
If only the sentences from the 0th sentence to the 500th sentence are to be summarized, a summary can be created according to the reading progress of each user. (Second Embodiment) An example of the configuration of an information presentation apparatus according to a second embodiment is the same as that of FIG. 1 except that the amount of the document read by the user or the ratio of the amount to the entire document Depends on the length of the summary to be created.

With reference to the flowchart shown in FIG. 6, the operation of the document summarizing section 4 for generating a summary will be described. That is, FIG. 6 shows the processing operation of step S5 in FIG. 2 in more detail.

At the start of the actual summary creation processing, the document summarizing section 4 first calculates the data amount of the document up to the location indicated by the bookmark information (the data amount of the document that the user has read so far). (Step S21). For example, when the bookmark information is represented by the number of bytes from the head of the document, the number of bytes may be used as it is as the data amount. Next, the data amount of the entire document is obtained (step S22), and the ratio of the calculated data amount of the document up to the location indicated by the bookmark information to the data amount of the entire document is obtained (step S23). For example, when the bookmark information is represented by the number of bytes from the beginning of the document, it can be obtained by dividing the number of bytes by the data amount of the entire document.

Then, a parameter of the digest length is determined from this value (step S24). The parameter of the digest length may be the number of sentences constituting the digest, the ratio of the number of characters of the digest to the entire document, or the like. For example, for a user who has not yet read only 20% of the entire document, the document before the designated bookmark position is 100-20 = 80.
A user who has presented the summary compressed to% and has read 80% of the entire document is presented with a summary obtained by compressing the document before the designated bookmark position to 100-80 = 20%. That is, the degree of compression of the summary is increased as the reading is continued. In this way, it is possible to avoid a situation in which the summary part becomes longer as the reading progresses and becomes cumbersome.
Also, as you read, your understanding should grow, so short summaries will probably be sufficient.

Instead of calculating the data amount of the entire document and calculating the ratio of the data amount of the document up to the position of the designated bookmark, the length of the summary is calculated only from the data amount of the document up to the position of the designated bookmark. May be determined. In this case, for example, for a user who has read 100 sentences, a summary of (100) ^1/2 = 10 sentences is given to 10,000 users.
For the user who has finished reading the sentence, a summary of (10000) ^1/2 = 100 sentences is created. (Third Embodiment) FIG. 7 is a diagram showing a configuration example of an information presentation apparatus according to a third embodiment of the present invention. FIG.
The same parts as those described above are denoted by the same reference numerals, and only different parts will be described. That is, in FIG. 7, a time management unit 8 is further provided.

The time management unit 8 measures the time from when the display unit 1 starts displaying a document to when bookmark information is input by the user, that is, the time that the user spends reading the document. The document summarizing section 4 determines the length of the summaries according to the measured time.

Referring to the flowchart shown in FIG. 8, the processing operation of the information presentation device of FIG. 7 will be described. In addition,
8, the same parts as those in FIG. 2 are denoted by the same reference numerals, and only different parts will be described. That is, the processing of step S5 in FIG. 2 is replaced with the processing of steps S31 to S34 in FIG.

The time management unit 8 monitors when the display unit 1 starts displaying a document and when bookmark information is input by the user. When these events occur, the time ( The document display start time and bookmark information input time) are stored in the storage unit 3. In particular, when bookmark information is input, the time is stored in the storage unit 3 in association with the bookmark information.

When starting the actual digest creation process, the document digester 4 first reads the document display start time and the bookmark information input time from the storage 3 (step S3).
1). Next, by subtracting them (bookmark information input time-document display start time), the time during which the user has displayed the document (document display time) is calculated (step S32). Then, a parameter of the digest length is determined based on the calculated time (step S33). For example, if the user took a long time to enter the bookmark information, it is considered that he / she had read it carefully. I think you don't know well,
An operation such as presenting a summary with a low degree of compression is performed.
Specifically, for example, the percentage to be compressed with respect to the data amount of the entire document may be obtained from the following equation (1).
In the equation (1), min (a, b) is a and b
Means to select the smaller value.

100 × min (1, α / document display time) α: constant (1) By using Expression (1), the percentage of the data amount of the entire document to be compressed is determined to obtain the document display. The longer the time, the shorter the summary.

When the user proceeds to read the document while interrupting it many times in the middle, the time management unit 8 sets the document display start time, the bookmark information input at each interruption, and the input time. Are all stored in the storage unit 3, and based on the information stored in the storage unit 3, the document summarizing unit 4 is stored.
Then, the total time that the user has spent reading so far may be calculated to determine the length parameter of the summary. Alternatively, even if there is an interruption in the middle, the document is read for a long period of time by calculating the total time of the document display time including the interruption time only from the difference between the initial display start time and the latest bookmark information input time. Therefore, a detailed summary may be added to a document whose contents may be forgotten.

Further, the document summarizing section 4 combines the data amount of the document up to the position of the designated bookmark with the above-described document display time and uses the data as an index for determining the length of the summary. Is also good. For example, the speed at which the user is reading the document may be calculated from both, and the parameter of the digest length may be determined based on the calculated speed. The speed is determined, for example, by selecting another bookmark information exceeding a predetermined data amount from one piece of bookmark information (or the top of the document) and immediately after the former bookmark information is input (or the top of the document). From the document display start time, the input time of the latter bookmark information, the former bookmark information (or the head of the document) and the latter bookmark information, it can be obtained by the following equation (2), for example. In equation (2), for convenience, the former bookmark information (or the beginning of the document) is called a first document position, and the latter bookmark information is called a second document position.

(Second document position−first document position) / (bookmark information input time−document display start time) (4) (Fourth Embodiment) FIG. 9 shows a fourth embodiment of the present invention. It is a figure showing the example of composition of the information presenting device concerning an embodiment. The same parts as those in FIG. 1 are denoted by the same reference numerals, and only different parts will be described. That is, FIG. 9 further includes a mark information input unit 9, a mark part extraction unit 10, and an extraction language dictionary 11.

In the information presenting apparatus shown in FIG. 9, the user places a mark on an important part while reading a document displayed on the display screen of the display unit 1 in such a manner as to mark an important part with a pen when reading a printed matter. Then, using the mark information, a summary of the portion that has been read by the user is created.

The mark information input unit 9 includes a keyboard, a touch panel, a pointing device such as a mouse, and an input device such as a pen, and is provided at a desired position (for example, a character string) in the document displayed on the display unit 1. This is for inputting a mark such as an underline or a circle mark. Here, the position information of the location specified by the user through the mark input is referred to as mark information. The mark information input unit 9 does not need to be provided separately from the operation unit 6, but may be integrated with the operation unit 6 and input the mark information from the operation unit 6.

FIG. 11 is a flowchart for explaining the processing operation of the mark part extracting unit 10 of FIG. First, the user looks at the document displayed on the display unit 1,
For example, as shown in FIG.
, A mark is input at a desired location that is likely to be important in the document. The mark information input by the user is passed to the mark portion extraction unit 10.

The mark part extracting unit 10 receives the mark information and performs a morphological analysis as described in, for example, "Basics of Natural Language Analysis" (Hozumi Tanaka, Sangyo Tosho). With reference to the extraction language dictionary 11, components (words, phrases, etc.) of the document are cut out,
A range in the document which is considered to be indicated by the mark information is identified (steps S41 to S42). The character string in the document identified in this way is called a mark part. The extraction language dictionary 11 is a dictionary in which grammatical rules and the like necessary for morphological analysis are registered in advance.

Next, the mark part extracting unit 10 instructs the display unit 1 to display the mark information or the mark part together with the document currently being displayed on the display screen of the display unit 1 (step S43). For example, FIG.
As shown in (b), the character string corresponding to the mark part extracted by the mark part extraction unit 10 is displayed with a highlighted display such as a surrounding display and a special display. Then, the mark portion is passed to the document summarizing section 4 (step S44).

In the document summarizing section 4, the mark portion extracting section 10
An abstract is created based on the mark portion received from the, ie, the character string (for example, by registering the character string as a keyword for creating an abstract in the abstract language dictionary).

The method of inputting mark information and the method of identifying a mark portion are not the gist of the present invention, but may be a known technique put to practical use in a pen input personal computer or the like.

FIG. 12 is a flow chart for explaining the processing operation of the information presentation device of FIG. FIG.
In FIG. 2, the same parts as those in FIG. 2 are denoted by the same reference numerals, and different parts will be described. That is, in FIG. 12, step S5 in FIG. 2 is replaced with step S51, and a mark portion obtained from mark information input by the user is used when creating an abstract.

In step S51, when an abstract is generated from a document, the mark portion is included in the abstract.
As the simplest summary generation method, a summary listing mark portions may be used as the summary. Alternatively, a sentence or a paragraph including a mark portion may be mechanically extracted.

The above-described input of mark information, identification of a mark portion, and generation of a summary will be described more specifically.
FIG. 10A shows that when a document including four sentences is displayed on the display screen of the display unit 1, the user inputs a mark at a desired position from the mark information input unit 9 while viewing the display screen. This is an example of such a case.

In this case, underlined characters such as "OO" and "XXX", and "□□□□"
A mark is drawn on the character string using the pen input device (mark information is input), and it can be seen that the user attaches importance to these character strings.

For such mark information, the mark portion extraction unit 10 identifies the mark information as shown in FIG. That is, a morphological analysis is performed on the document displayed on the display screen, and the document is divided into words, so that the range in which the mark is described as “□□□□” in FIG. Is not clear, the presence or absence of designation for each word (for example, whether or not there is an overlap with a mark input by the user) is determined, and FIG.
As shown in (b), a clear specified range can be cut out as a mark portion.

When the user inputs the mark information as shown in FIG. 10 (a), what is actually displayed on the display screen in step S43 of FIG. 11 is as shown in FIG. 10 (a).
The input mark information itself may be used.
It may be only the mark part extracted by the mark part extraction unit 10 like 0 (b), or both.

For example, after receiving an instruction from the user to confirm the mark displayed on the display screen as shown in FIG. 10B, the mark is transferred to the document summarizing section 4.

The document summarizing section 4 uses the mark portion as a keyword, and for example, from the document, "XX and XXX are becoming widespread. However, there is a problem that □□□□ is…”. Then, a simple summary can be generated by extracting a sentence including a mark portion and listing all the sentences.

Alternatively, a sentence containing a larger number of marked portions may be considered more important, and a summary may be created by arranging the sentences in descending order of importance. For example, FIG.
In the case of (b), the first sentence having two mark parts of “XX” and “XXX” becomes the most important, and then “□□”
The sentence containing “□□” is important. Therefore, for example, when an abstract consisting of one sentence is sufficient, an abstract consisting only of the first sentence is created, and when an abstract consisting of two sentences is required, an abstract may be created by listing these two sentences.

In FIG. 10, the pen information input section 9 has been described as an example in which a pen or the like is used to directly input information on a display screen. However, input of mark information and identification of a mark portion are simpler. You may. For example, the user designates mark information in units of sentences by clicking a specific sentence with a mouse. Then, the specified sentence may be directly treated as a mark portion. In the case of a document including a plurality of chapters, the user may click on the title of a chapter that is determined to be important, so that the entire chapter becomes a mark portion.

As described above, according to the fourth embodiment, by creating an abstract based on a character string extracted from mark information input by a user, interest, understanding, importance, etc., differing for each user. A summary can be created in response to such a summary, and presentation of such a summary makes it easier to understand the read portion of the document.

The functional units described in the first to fourth embodiments can be used in appropriate combinations. Also, as shown in the flowcharts of FIGS. 2, 3, 6, 8, 11, and 12 described in the first to fourth embodiments, the display unit 1, the bookmark information input unit 2, The functions of the document summarizing section 4, the time managing section 8, the mark information input section 9, and the mark portion extracting section 10 are programs that can be executed by a computer, such as a floppy disk, a hard disk, a CD-ROM, a DVD, and a semiconductor memory. It can also be stored in a recording medium and distributed.

[0058]

As described above, according to the present invention,
When presenting a document, for a part that the user has already read, by presenting a summary, it is possible to maintain consistency between the part already read and the part to be read,
Even when a long document is read while being interrupted many times, the user is not inconvenienced. In other words, by presenting a summary of the already read portion of the document, the user can recall the contents of the already read portion and understand the points, It is possible to clearly grasp the position in the inside and the connection with the part to be read in the future.
