DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus for displaying an abstract, a keyword, or related information relating to a specific range in data, and promoting the understanding and interest in reading a digitized document.

[0002]

2. Description of the Related Art A device called a so-called electronic book in which a document or the like is stored on a floppy disk or a memory card and displayed on a portable display device is known.
As a document in the electronic book device on the left, a dictionary, an encyclopedia, a novel, and the like are often used. In dictionaries and encyclopedias, headings are associated with the contents of headings and stored in a memory such as a floppy disk or CD-ROM.
By inputting a heading from the heading input means and executing a search operation, the contents of the associated heading are displayed. Some headings are indexed, for example, "Aioueo" to make searching easier. When the content of the document is a reading material such as a novel, the display is configured so as to resemble a book made of paper as much as possible, and the page of the book is turned by page switching means represented by buttons for forward and reverse. It switches between pages and performs reading.

Further, according to an electronic encyclopedia recently released by several companies, link information associated with a CD-ROM or a resource on a network is added to a headline or a specific keyword of the headline content, thereby providing a link. There is known a technology capable of displaying the preceding information.

Further, a portable display device disclosed in Japanese Patent Application Laid-Open No. 5-314732 has a text storage means in which text is stored for each page, and text data stored in the text storage means for each page. Coarse line storage means storing coarse line data indicating the outline contents up to the front of each page, and display means for displaying the text in the page or the outline contents according to the data read from each of the storage units. ,
Switch means for turning on / off the power of the display means, page number storage means for storing a page number displayed on the display means at the time of the off operation in response to the off operation of the means, and the switch In response to the turning on of the means,
A technique is disclosed that has control means for reading coarse line data up to the page indicated by the page number data from the coarse line data storage unit and displaying the schematic content on a display unit based on the read coarse line data. ing. Japanese Patent Application Laid-Open No. Hei 5-314732 discloses a technique which has a page number designating means and, when a page number is designated, displays coarse line data corresponding to the designated page number on a display means.

A document summarizing apparatus disclosed in Japanese Patent Application Laid-Open No. Hei 7-36896 relates to an apparatus for automatically summarizing a document by selecting an area of the document, and manages a seed list and a stop list. If the summary is too long, region selection processing is performed on the summary to create a shorter summary. This region selection process is repeated until a digest having the desired length is generated. As described above, a technique for adjusting the length of the digest to be equal to or less than a predetermined length has been disclosed.

[0006]

However, in the above-mentioned conventional example, in order to obtain a summary of the document (including the expression of coarse lines), each page of the text data stored in the text storage means is provided before each page. Is provided, and a large amount of summary (coarse line) data is required. Even if the storage unit of the coarse line data is not a page unit but a chapter unit, for example, it is necessary to prepare the coarse line data up to the chapter before the chapter for each chapter, and the amount of the coarse line data increases. There was a problem.

Further, in the above-mentioned conventional example, when the detail and length of the summary are changed, it is necessary to prepare the summary data for the variation, and there is a disadvantage that more summary data is required.

[0008] Further, in the above-mentioned another conventional example, a technique for automatically adjusting the length of a digest to a certain length or less is described. A method of adjusting the length of the summary by cyclically performing the summarization process has been adopted, and since data once dropped from the summary data cannot be restored to the detailed summary data, there is a problem in the quality of the summary.

In the conventional method of viewing related information associated with a keyword or index, the content of the related information is fixed, and the keyword or index is determined according to the type of document content or the amount of the document that has been read. There was a problem that it was not possible to promote the reader's understanding and interest by changing the content and items of the related information related to.

Further, in the above conventional example, the related information is not linked to the keyword or index in the summary, and the summary or the related information is determined according to the type of the document content or the amount of the document that has been read. If the presented summary does not allow for a complete summary, most of the duplicated content will be re-read and displayed, and the reader will be able to view the duplicated summary document. There was a problem that it could be read.

[0011] In addition, the above-mentioned conventional example has a problem that it takes a long time for summarization since a summary is generated from the original text each time.

Further, in the above-described conventional example, since the digest is generated by the machine processing, there is a problem that the quality of the digest is lower than that of the digest by the human hand in the processing of the context and the scope.

[0013] Further, in the above-mentioned conventional example, since there is no mechanism for restricting the summary and related information provided corresponding to the current reading position, good medicine and related information for the unread area may be displayed. For example, when reading a document with a story such as a mystery novel, there is a problem in that a summary or related information that distracts the interest of subsequent reading is provided.

According to the present invention, a plurality of summary data summarizing the contents of a specific range of main data with different details are stored in a summary data storage means, and the summary data is combined to control the output of the summary data. It is an object of the present invention to provide a document processing for dynamically changing and outputting an abstract based on the amount of a document that has been read, the page being displayed, and the content of the document.

Further, the present invention is also applicable to the case where related information for a keyword or an index is output, based on the amount of the read document, the displayed page, and the content of the document, similarly to the summary. An object of the present invention is to provide a document processing for dynamically changing and outputting information.

S38 is a related information display mode, which will be described after the description of claim 5 and subsequent claims is completed.

Note that S30 represents a case where the process proceeds from S31 to S36 without branching, and is a processing module for controlling display of main data. In the present invention, this mode is referred to as a main data display mode in contrast to the summary display mode and the like.

First, the summary display mode will be described.
FIG. 20 is a diagram illustrating an example of a flow of a process regarding the summary display mode. S110 is y in the S33 module of FIG.
This is a processing module representing a state of branching to es, in which the button 22 of the summary selection means is pressed to enter a summary display mode. S111 is a processing module that acquires data in the range of the main data displayed so far, and can acquire data from FIG. S112 is a processing module for determining the summary range, and determines the range based on the user's instruction using the user interface of FIG. This processing module can be omitted by setting the default between the minimum index number and the maximum index number in FIG. In that case, FIG.
Can also be omitted.
Step S113 is a processing module that determines summary configuration conditions such as the detail level of the summary and the gradient of the detail level of the summary using the user interface of FIG. S114 is a processing module for actually starting the summary, which is normally performed by pressing the summary selection means 22. When changing the summarization range or the summarizing conditions, the process returns to S112. S115 is a processing module for collating the summary data from the structure of FIG. 5 based on the summary range and the summary configuration condition determined above. S116
Is a processing module that generates summary data that matches the conditions. S117 is a processing module that displays the generated summary data.

FIG. 21 is a detailed flow chart of the processing module S113 for determining the summary configuration condition in FIG. For simplicity, the main data is composed of three chapters, and it is assumed that the user starts reading from chapter 1 and finishes reading chapter 3, and the default chapter detail level is set to 3 (corresponding to FIG. 5). ). S120 is a processing module for displaying the user interface for setting the summary configuration condition in FIG. 6 and selecting an item. S131 is a processing module for determining whether or not a summary has already been displayed. When the summary is not displayed, it is determined whether or not “uniform” of the user interface is selected (S12).
1). Either one of the selection items “uniform” and “nearly detailed” is selected.

If "uniform" is not selected, it is confirmed whether the end of the chapter is currently displayed (S122).
If the end of the current chapter is displayed, the detail of the chapter having the maximum index number of the history information is obtained (S12).
4). In this case, since there is no value M of the degree of detail, a default value is applied and a value 3 is obtained.

Next, a gradient distribution ratio K is obtained. This value is S
The ratio (L / M) between the range L of the summary obtained in 112 and the above M
(S125). L is represented by L = 3-1 + 1 = 3, for example, when the range of the summary is from Chapter 1 to Chapter 3. It is determined whether L / M is an integer (S126).
When L / M is an integer, the detail level is changed by K from the first chapter to the last chapter of the main data to be summarized. In this case, the summarization range is 3 chapters, and the detail level is 3, so K is 1. K3 is the detail level 3, Chapter 2 is the detail level 2, and Chapter 1 is the detail level 1. (S12
8). These information are stored (S129). S1
If K does not become an integer at 26, L is decremented by 1 until K becomes an integer, and the degree of detail is sloped by an integer K from the page at which the integer becomes the number to the last chapter of the summary range. The chapters out of the range in the above processing are adjusted to the minimum detail (S127).

If "uniform" is selected in S121, the detail level of the summary page or the page of the final display of the summary range is read, and the value is set for all chapters (S130, S128). . If there is no summary detail data, apply the default value.

On the other hand, if the summary is displayed in S131, "longer", "shorter", or "exit" is selected from the menu of FIG. These menus have three choices so that only one can be selected. If "Longer" is selected (S132), the detail of each chapter of the currently displayed summary is counted up one by one (S133). When "shorter" is selected, the count of the detail level is reduced by one (S134). When "exit" is selected (S134), the display is performed again (S13).
6).

The above embodiment relates to the case of setting the configuration conditions using the user interface of the summary selecting means 5 shown in FIGS. The default value is set to, for example, the detail level of the chapter is set to 1, and the range of the summary is determined to be all of the main sentences displayed so far, and the summary is executed by simply pressing the summary selection means 22. In addition, it is also possible to realize claims 1 to 3 of the present invention by designing so that the detail of the summary is increased each time the summary selecting means is pressed.

FIG. 22 is a diagram showing an example of a detailed flow relating to S115 and S116 in FIG. S140 is S1
This module refers to the summary data obtained in step S12 or S113, and the method of accessing the summary data is omitted since it was performed at the time of the description of FIG. S141 is a processing module for checking whether the main data has been displayed up to the end of the chapter or checking the display history. This is already determined in S122 and stored in the digest control device in S129, so that it is used.

If the main data is displayed in the middle of the chapter, S123 is executed to execute the summarization within the displayed range.
The summary of the chapter is terminated at the final display position ratio R obtained in (S142). If the chapter summary is terminated by R,
The end of summary data may be in the middle of a sentence. If the summary is in the middle of a sentence, the data up to the punctuation of the sentence at which the sentence is completed is added to the summary data (S143, S144).
The summary data of the chapter is loaded into the output summary buffer, and when the range of the summary extends over a plurality of chapters, the summary is connected in ascending summary of the chapter (S145, S146). This is repeated until the last chapter in the range of the summary (S147).

As another embodiment in which the main data is displayed halfway through a chapter, the summary of the chapter is ignored,
It is also possible to summarize the previous chapter.

FIG. 23 is a diagram showing an example of the flow of the processing relating to S39. Page switching means 20, 2
A signal output when 1 is pressed is acquired (S1), and it is determined whether the next page switching means 21 is pressed or the previous page switching means 20 is pressed (S2). When 20 is pressed, assuming that the number of overlap lines in the display is n, the display is advanced by (current number of display lines-n) lines (S5).
The number of the display index of the main data is obtained (S6).
On the other hand, in the case of switching to the previous page, on the other hand, the index number is obtained by returning (−n) lines from the current display line number (S
3, S4).

Next, the read range is updated. This is performed by updating the minimum index number 111 and the maximum index number 112 in FIG. That is, when the page to be displayed is changed and the value of the display index number 110 is updated, the value is compared with the value of the minimum index number 111 (S7). If the value of the display index number 110 is smaller than the value of the minimum index number 111, the value of the minimum index number 111 is updated to the value of the display index number 110 (S8). Similarly, if the value of the display index number 110 is larger (S9), the maximum index number 112 is updated (S10).

By the means and method described above, it is possible to dynamically change the amount or configuration of the summary data to be output based on the range of the displayed main data or the position of the main data. In addition, it is possible to dynamically change the amount or configuration of the summary data to be output based on an instruction from the user.

FIG. 8 is an example of a block diagram showing the configuration of the document processing apparatus according to the fifth to tenth aspects. FIG.
In FIG. 2, means common to those in FIG. 1 are denoted by common numbers, and description thereof is omitted. The page switching unit 12 is a page switching unit such as a key, a button, or an icon for switching the content displayed on the display unit 7. The page switching includes, in addition to a page meaning one screen of the display device, switching between the display of one window of the display screen, a keyword or data relating to a specific range in data, related data, or main data. In. The history storage unit 13 is a unit that stores the history of the page displayed on the display unit up to the present time. The related data storage unit 14 stores a configuration of the related data and pieces of related data having different contents. This is a means for storing.

The related data selection means 15 is a means for selecting the structure and contents of the related data to be output. The related data control means 16 receives the main data as input, and selects the structure or contents selected by the user with the related data selection means. This is a means for performing a series of controls for generating related data of contents and displaying the data on the display means 7.

The keyword in the main data storage means 1 is, for example, the name or place name of a person appearing in a novel or manga, and the related information on the keyword is an example of a person appearing in a novel or manga. For example, the person's name, age, occupation, personality, and behavior of the person. Further, the specific range in the data of the main data storage means 1 may be image data or a part of the image data in that range.

Since a specific keyword can be assigned to a specific range in the data, hereinafter, in the present invention, the term "keyword" is used as a keyword or a concept word including the specific range in the data.

FIG. 9 is a display example of related data relating to the keyword "Taro Hayakawa". Reference numeral 80 denotes an item of the keyword-related data, and reference numeral 81 denotes a value (content) of the item. Reference numeral 82 denotes a related data item relating to the keyword “Taro Hayakawa”, which in this case is “basic data”.

FIG. 10 is a display example of the related data related to the related data item “related person” of the keyword “Taro Hayakawa” in the main data chapter 3. 83 is related data. Reference numeral 84 denotes the content of the related data item, and it is possible to know that "Taro Hayakawa" is an occupational business owner and that he has a daughter named Fujiko. The content of the related data item may be multimedia data including chart data, voice, etc., in addition to text data. Also,
Related data items include basic data, characteristics,
Actions, background, related places, related products, related times, performance, etc. can be added or reduced according to the type and content of main data.

It should be noted that the keyword-related data is manually attached in units of preset units (for example, chapters together with the summaries described so far). Therefore,
The content of the related data related to the keyword differs depending on the chapter. For example, as in FIG. 5, the main data is composed of three chapters. If FIGS. 9 and 10 are related data for “Taro Hayakawa” in Chapter 3, the main data is the keyword “Hayakawa” in Chapter 1. Basic data on "Taro"
Examples of related data of the related data item “related person” are shown in FIGS. 11 and 12, respectively. The related data of “Taro Hayakawa” from the age of 22 to 28 is described, and the relationship with Kyoko Matsushita is described. Have been.

FIG. 15 is a diagram showing an example of a data structure for explaining a method of accessing related data relating to a keyword. In FIG. 15, reference numeral 90 denotes a keyword, and a main data position 91 indicates the position of the first character of the keyword and the position of the last character of the keyword in the main data. The value can be assigned by the number of bytes, or can be represented by the number of pixels of the display means as in the case of image data. The related data address 92 stores a pointer to the related data 93, and the related data as shown in FIGS. 9 to 14 is stored before the pointer indicated by the pointer 92. The main data position, the related data address, and the related data are all represented by an array structure, and can be accessed by an index number. In the case of data having a variable length structure such as a related data address, a data amount corresponding to the number of items 94 is allocated. Further, different related data addresses such as related data address [2] and related data address [3] in the drawing may indicate the same related data. By doing so, it is possible to reduce duplication of related data and reduce storage capacity.

FIG. 16 is a diagram for explaining an example of the structure of the related data address 92. Reference numeral 94 stores data (k in the figure) for managing related data items.
Reference numeral 95 stores a related data item heading, and reference numeral 96 stores a pointer to the entity of the related data. For example, related item 1 is “basic data” and related item 2
Is "related person" or the like. This item has a different configuration depending on the content of the main data. For example, when the content related to a person or a place name is the main, such as an inference novel, [basic data], “related person”, “background”, “ For example, when an article such as a technical document is mainly used, items such as [basic data], "features", and "related products" are stored.

FIG. 17 is a diagram for explaining an example of the internal data structure of the related data 92. 97 is an exploded view of 96 in FIG. Address [1] is related data address 1, the value of item [1] is “basic data”, address [2] is related data address 2, and the value of item [2] is “related person”. It means there is. 98 is a diagram showing the internal structure of related data pointed by the address pointer 97. Reference numeral 99 denotes an example of the data structure of the content of the related data item “basic data” of the keyword “Taro Hayakawa”, 99 denotes a related data entity item, and 100 denotes the content. The data itself has the contents shown in FIG. 99 is information known to the designer of the document processing apparatus, and can be omitted. Here, the header information is for distinguishing the storage form of the content of the information, for example, “txt” for text data and “bmp” for bitmap data.
Etc. can be used.

The address [2] of 96 relates to a related person, and the pointer of 97 points to 101.
The entity of 100 is “Kyoko Matsushita [name]”, and [name] is an item name, which means that it is used as a key for searching for information. 102 represents the entity of 96 addresses [3]. FIG. 18 is a diagram for explaining an example of the page switching means 12 and the related data selection means 15 for extracting related data from a keyword in the main data. 103 is a page switching of the main data,
It is a direction key that also serves as an item selection of a user interface of related data or a summary. Main data is display means 7
Is displayed in the reverse direction with the left / right keys,
The displayed page can be switched in the forward direction. 103
Are used to move the cursor 107 to the keyword 106. The down key moves the cursor to the next keyword, and the up key moves the cursor back to the previous keyword.

Reference numeral 104 denotes an example of a summary selecting means, which is realized by function buttons and keys for switching between a main data display mode and a related data display mode. If 104 is pressed in the main data display mode, the mode shifts to the related data display mode.

In the related data display mode, a related item menu of a keyword (in this case, “Taro Hayakawa”) is displayed. When a menu selection item, for example, “basic data” is selected, FIG. 10 is displayed. To shift to the main data display mode again, 104 is displayed while the related data is displayed.
Press again. If, for example, the right arrow key 103 is pressed while the related item menu is displayed, a menu for setting the range of the related data is displayed. This can be common with the summary (FIG. 7).

When the right arrow key 103 is further pressed while the range of the related data is determined, a menu for changing the contents and structure of the related data is displayed (FIG. 6). If "Longer" is selected, related data that is more detailed than the displayed related data is displayed, and if "Shorter" is selected, related data that is simpler than the displayed related data is displayed.

FIG. 13 is used to explain that the related data changes dynamically depending on the display history or the menu selection in FIG.
And FIG. 14 are added. FIG. 13 shows related data relating to the related data item “basic data” for the keyword “Taro Hayakawa” obtained by integrating the first to third chapters, and FIG. 14 shows the data related to the keyword “Taro Hayakawa” of the first chapter in the main data. FIG. 12 shows an example of related data obtained as a result of selecting “shorter” by the related item selecting means.

The data structure described above and FIG.
How the result of the related data is obtained will be described with reference to the processing flowchart of FIG. The general flow is shown in FIG. 19, and the related information starts from the point at which the process has shifted to the related information display mode in S38. The general flow relating to the related information processing mode can be commonly used by replacing the summary in FIG. 20 with the related data. However, since the summary selecting means and the related data selecting means are slightly different, the explanation will be briefly added. The processing module is the same as in FIG. 20,
It is distinguished by "'".

Step S110 'is a processing module showing a state of branching to "yes" in the module S33 of FIG. 19, and is a processing module for pressing the button 104 of the related data selection means to enter the related data display mode. S111 ′ is
This is a processing module for acquiring data in the range of the main data displayed so far, and data can be obtained from FIG. S112 'is a processing module for determining the range of the related data, and determines the range based on the user's instruction using the user interface of FIG. This processing module can be omitted by setting the default between the minimum index number and the maximum index number in FIG. In that case, the user interface in FIG. 7 can also be omitted.

Step S113 'is a processing module for determining the related data configuration conditions such as the related data detail level and the slope of the related data detail level using the user interface of FIG. S114 'is a processing module for actually starting the generation of the related data.
This is done by pressing. When changing the related data range or the related data configuration condition, the process returns to S112 ′. S
Reference numeral 115 'denotes a processing module for collating the related data from the structures shown in FIGS. 15, 16, and 17 based on the related data range and the related data configuration condition determined above. S11
6 'is a processing module for generating related data that matches the conditions. S117 'is a processing module for displaying the generated related data.

FIG. 24 is a detailed flow chart of the processing module S113 'for determining the related data configuration condition. For simplicity, it is assumed that the main data is composed of three chapters, the same as the summary, and that the user has started reading from Chapter 1 and has finished reading Chapter 3. Default chapter detail level is 1
(Easiest). S220
Is a processing module for displaying the user interface for setting the summary and common related data configuration conditions in FIG. 6 and selecting the displayed menu item. S231 is a processing module that determines whether or not the related data has already been displayed. If the related data is not displayed, it is determined whether or not “uniform” of the user interface is selected (S221). Either one of the selection items “uniform” and “nearly detailed” is selected.

If “uniform” is not selected, that is, if “nearly close” is selected, it is confirmed whether or not the end of the chapter is currently displayed (S222). If the end of the chapter is currently displayed, the number of chapters in the history display is calculated from the difference between the maximum index and the minimum index in the history display. In this case, since the main data is composed of three chapters, this value M is 3 (S224).

Next, the level of detail of the related data will be described. The detail level of the related data is not stored as explicit data unlike the case of the summary. The default is 1, which is the simplest related data. As a preparation for generating related data having a high level of detail, the value of the level of detail counter P is increased by one (S224). In order to create related data with a more detailed level, a search is made to see if there is an item enclosed in [] in the contents of the related data (S226).

In the case of the present example, there is no item enclosed in [] in the contents of the basic data of “Taro Hayakawa”. For the basic data, the process proceeds to S228. On the other hand, the contents of the related person include []. this is,
This indicates that there is a possibility that there is basic data having the item. In the case of the present example, since [Kyoko Matsushita] has a [name], an index whose name is Kyoko Matsushita is searched, and from the related data, it can be seen that Kyoko Matsushita is in dating with Noguchi. Further, assuming that [person name] is embedded in both Noguchi and Tomoko in the related data of Kyoko Matsushita, looking at the basic data of Tomoko Noguchi reveals that the occupation is a pawn shop. The additional search of the related data is performed by incrementing the detail counter P by one each time the repetition is performed, and recursively repeating the above M times until the content of [] disappears (S22).
5) Save related data with different levels of detail (S22)
9). The related data item of “Taro Hayakawa” thus obtained is “related person” and the related data with the detail level of 1 is shown in FIG. 14, and the related data with the detail level of 3 is shown in FIG.

Next, the gradient distribution will be described. The detail counters P and M are compared. If P = M, P
= M-P + 1 determines the detail of each chapter. For example, when M = 3 and P = 2, P = 2 in Chapter 3 and P = 1 in Chapter 2
And P = 0 in the first chapter, but when P is smaller than 1, it is set to 1. The module that performs this processing is S228.

If "uniform" is selected in S221, the default detail level 1 is set for all chapters (S230).

On the other hand, if the summary is displayed in S231, the user selects “longer”, “shorter”, or “exit” in the menu of FIG. These menus have three choices so that only one can be selected. When "Longer" is selected (S232), the detail level of each chapter of the currently displayed summary is counted up one by one (S233). If “shorter” is selected, the count of the detail level is reduced by one (S234). When "exit" is selected, the display is performed again (S235).

FIG. 25 is a diagram showing an example of a detailed flow relating to the processing modules S115 'and S116' in which the summary of FIG. 20 is changed to related data. S240 is a module that refers to the related data acquired in S112 'or S113'. The method of accessing the related data is shown in FIG.
5, since it was performed at the time of description of FIG. 16 and FIG.
S241 is a processing module that checks the display history to determine whether the main data has been displayed up to the end of the chapter. This is S2
Since it has already been determined in S22 and stored in the digest control device in S229, it is used. If the main data is displayed in the middle of the chapter, the related data of the chapter is terminated at the final display position ratio R obtained in S223 to execute the summarization in the displayed range (S242). For the termination of the related data, R is added to the number of items of the related data, and the number is rounded down to the nearest whole number (S248). If the integrated amount is less than 1, only one item is output (S244).

The related data of the chapter is loaded into the related data buffer to be output, and when the range of the related data extends over a plurality of chapters, the related data of the chapter is connected in ascending order (S245, S246). This is repeated until the last chapter in the range of the related data (S247). By the above method,
FIG. 13 shows an example of basic data of “Taro Hayakawa” from Chapter 1 to Chapter 3.

The above embodiment is based on the method of selecting the configuration condition of the related information using the user interface shown in FIGS. As another example, there may be cases where these user interfaces are not used. This corresponds to the case where the configuration condition of the related data is determined using the default. For example, the range of the related data is set to the range stored in the display history storage means, the detail level of the related data is uniformly set, and the length of the related data is set. This can be achieved by setting the default longer.

In this case, there are the following two methods for adjusting the length of the related data. One is the case of prioritizing the addition of the related data of the item [k] in FIG. 16 first, and the other is fixing the number of items [k] and adding additional information by linking the related data. This is a case where depth is prioritized. In the present invention, any of these methods may be used.
When the default is used, the related data of the default level of detail is displayed by pressing the related data selecting means 104 in FIG. Count up one by one.

As described above, it is possible to dynamically change the amount or configuration of the related data to be output based on the range or position of the displayed main data. Further, it becomes possible to dynamically change the items of the related data to be output based on the contents of the main data. Further, it becomes possible to dynamically change the amount or configuration of the related data to be output based on the instruction from the user.

The arrangement of the related data selecting means and the page switching means is not limited to that shown in FIG. Further, the related data selection unit and the page switching unit can be shared with the summary data selection unit and the summary page switching unit.

Finally, an embodiment according to claim 10 will be described. This corresponds to a case where relevant data is displayed for the summary output by the summary control unit.
This corresponds to, for example, the left and right arrow keys of 103 in FIG.
05, a summary is output, and
It can be realized by displaying the related data using all the keys. Since the generation and display of the summary and the related data have been described in the individual processes, the description is omitted here.

As described above, the related data is associated with the keyword in the pre-summary data, and the amount and composition can be dynamically changed according to the range, position, and user designation of the abstract.

According to the present invention, it is only necessary to prepare the summary data of each chapter alone (including the expression of coarse lines) in the summary of the document. This eliminates the need to prepare for each chapter, and has the effect of reducing the amount of summary data.

Further, according to the present invention, even when the detail and length of the summary are changed, it is sufficient to prepare the summary data for each chapter, so that when the variation increases, the amount of the summary data can be further reduced. This has the effect.

Further, according to the present invention, since the high-quality summary data created by human hands is used as the basis, even if the length of the summary is automatically adjusted, the quality of the summary is not reduced. effective.

Further, according to the present invention, a summary can be generated by combining summary data, which are parts of a summary prepared in advance, and therefore, there is an effect that the speed is higher than that of generating the summary in real time. .

Further, according to the present invention, the summary has a high quality even if the summary is performed using the summary data by the human hand including the processing of the context and the scope.

Further, according to the present invention, the output amount and the structure of the related information associated with the keyword and the index can be changed according to the type of the document content and the amount of the read document. There is. In line with this effect, changes in the content and structure of related information related to keywords and indexes compensate for the disadvantages that were previously considered monotonous and reduced readers 'understanding and interests, and increased readers' understanding and interests. It leads to the effect of promoting.

Further, according to the present invention, related information is linked to a keyword or index in the summary, and the summary or the related information is changed according to the type of the document content or the amount of the document that has been read. Because of the change, even when the presented summary cannot be completely grasped, there is an effect that related information can be output effectively and reading can be made more efficient.

Further, in the above-mentioned conventional example, since the summary and related information are read only in the middle of the page, the summary and related data are not displayed until the end of the page. Even when reading a document with a story like that described above, there is an effect that a summary or related information that does not interest subsequent reading is provided.

Further, according to the present invention, with a small number of function keys,
You can display summary or related data,
