Description

  The present invention relates to a document visualization apparatus, a visualization method, and a program therefor, and particularly relates to a visualization method for comprehending a document as a whole when editing a document.

  Research related to document visualization has been conducted in a research area called “Information Visualization”. For example, Non-Patent Document 1 reports many such systems. However, most of them are related to methods for grasping the whole picture of a large amount of document space (document space). No report has been made on how to visualize a single document for editing purposes.

  In addition, many studies have compared the quality of written sentences between handwriting and using an editor or a word processor (collectively referred to as a word processor hereinafter). For example, it is disclosed in Non-Patent Documents 2 to 7. Among them, it is known that using a word processor makes the length of a sentence longer than that of handwriting (see Non-Patent Document 3 and Non-Patent Document 7). As one of the reasons, it has been pointed out that the writer cannot grasp the whole sentence due to the limitation of the size of the display (see Non-Patent Document 6).

In order to cope with such a problem, a normal word processor is provided with a function for displaying the length of the entire written document in numbers. However, this method has the following two problems.
(1) Many sentences have a hierarchical structure consisting of sections and chapters (hereinafter referred to as sections). In this hierarchical structure, it is not possible to know how long each section is.
(2) In the numerical display, the length of the sentence cannot be grasped intuitively. Even if the length of the sentence is provided as a numerical value, in order to recognize how much it actually becomes, it is necessary to convert it into another amount that can be recognized by the self. Moreover, in order to recognize which one of the two numerical values is large, calculation is required, and the cognitive load is high.

  As a countermeasure to the problem (1), some word processors make it easy to grasp the overall structure of a document by visualizing the hierarchical structure of sections. In addition, a device is devised so that the user can easily move to the position of the document by selecting a heading of a specific hierarchy. However, there is still a problem that it is impossible to grasp how long each hierarchy is.

  In order to cope with this problem, Patent Document 1 enables folding of a lower hierarchy of a document having a hierarchical structure, and when folded, the amount of sentences in the lower hierarchy (number of characters, number of sentences, number of figures and tables, etc.) A method of displaying numerical values so that they can be understood is proposed. However, the display form is also a numerical value here, and the problem (2) is still not solved.

  As a countermeasure to the above problem (2), the document search system “TileBars” introduced in Non-Patent Document 8 is proportional to the amount of information described in the document as well as the title of the document searched with a specific keyword. By displaying a rectangle such as a bar graph, the length of the search result document can be intuitively grasped. Specifically, the text document is segmented into chunks called tiles, and rectangles proportional to the number of the text documents are displayed. Furthermore, the number of search keywords appearing on each tile is calculated, and the tiles are color-coded in association with the appearance frequency. Thereby, it is possible to grasp where and how often the search keyword is used in the searched document.

  However, in the document search system disclosed in Non-Patent Document 8 above, although it may be sufficient to see the appearance position and frequency of the search keyword in the search result document, the document currently written for the purpose of editing In the visualization, it is necessary to visualize how long each section is. It is also necessary to visualize where and how each section has changed. If this is possible, the writer can cut or add to the contents of a section while looking at the overall distribution of the description.

  The present invention is proposed based on such a problem, and is a document visualization apparatus and visualization that can intuitively grasp the total amount of sentences having a hierarchical structure of sections and the amount of each section. It is an object to provide a method and a program thereof. Furthermore, it is possible to grasp where and how a specific word or sentence is used in each section.

  An information processing apparatus having a function of visualizing a document having a hierarchical structure according to the present invention includes a document holding unit that holds document data, and a hierarchy of document sections based on the document data held in the document holding unit. Hierarchical structure display means capable of displaying the structure in a tree structure, document amount visualization means for quantitatively displaying the document size of the section displayed by the hierarchical structure display means, and sections displayed by the hierarchical structure display means And a document display means capable of displaying the document content corresponding to. This makes it possible to intuitively grasp the document size (sentence length) of the document section. A section here corresponds to a section or chapter of a sentence.

  Preferably, when the graphic data such as a figure / table is included in the document data, the document amount visualizing means displays an identification indicating the appearance position of the graphic data in the section. This makes it possible to intuitively grasp the amount and position of the chart within the section.

  The document size is specified by the number of sentences (sentences), the number of paragraphs (paragraphs), or the number of pages, and the document amount visualizing means quantitatively displays the number of sentences, paragraphs, or pages. Good. The document amount visualizing means segments sentences, paragraphs, and pages in the segment, and displays the section document size in a graph by stacking the segmented blocks. As a result, the length of each section is known, and at the same time, it is possible to intuitively know how many paragraphs are in each section.

  Preferably, the document amount visualizing means is capable of displaying the document size of the upper or lower hierarchy section, and the document size of the upper hierarchy section is displayed together with the sum of the document sizes of the lower hierarchy belonging to the upper hierarchy. . Further, the hierarchical structure display means can open a lower hierarchy included in the upper hierarchy or close so that the lower hierarchy is included in the upper hierarchy, and the document quantity visualization means can display the lower hierarchy. Depending on the open / closed state of the document, when it is closed, the document size corresponding to the total amount of the lower hierarchy is displayed, and when it is opened, the display corresponding to the document size for each lower hierarchy is displayed. By enabling opening and closing of the lower hierarchy, for example, the length and shape of the bar graph change by the document amount visualization means. As a result, when the total amount of the document including the section structure and the distribution of the length of each section are intuitively grasped, it becomes possible to change the granularity of the depth of the section and to overview the entire amount.

  Preferably, the information processing apparatus further includes correspondence calculation means for calculating a relationship between a hierarchical position of the section in the hierarchical structure display means and a document position in the document display means, and the section displayed by the hierarchical structure display means When the specific item is selected, the corresponding document position is calculated by the correspondence calculation unit, and the corresponding part is displayed on the document display unit. By scrolling the corresponding portion of the document (section heading in the document), it is possible to easily move to a desired section of the document.

  Preferably, when a specific position of the document size visualized by the document amount visualizing unit is selected, the corresponding document position is calculated by the correspondence calculating unit, and the corresponding part is displayed on the document display unit. The This makes it possible to easily access a desired part of the document.

  Further, when a specific portion displayed by the document display means is selected, a corresponding position is calculated by the correspondence calculation means, and the calculated positions are the hierarchical structure display means and the document amount visualization means. Is identified and displayed. Thereby, it is possible to grasp what position the editing position of the document is in the entire document.

  When a specific document area is displayed by the document display means, the corresponding area is calculated by the correspondence calculation means, and the calculated area is highlighted by the document amount visualization means. Just like the global view of hypertext, the display position in the local view is colored and displayed as a rectangle in the global view, and this is applied to the document amount visualization means.

  Preferably, when the hierarchical structure of the section is changed, the changed hierarchical structure is held in the document holding means, and the document display means displays the document so as to correspond to the changed hierarchical structure. Further, the position of the block in the document amount visualizing means can be changed, and the document display means displays the document whose block order has been changed.

  Preferably, the information processing apparatus further includes character string search means for searching for a specific character string in the document, and the document amount visualization means displays an identification at a position corresponding to the appearance position of the searched character string. . When a specific position is selected from the appearance positions of the character strings displayed by the document amount visualizing means, the document display means displays the corresponding character strings. By selecting the search result, the corresponding position of the document is scrolled and displayed.

  The document display means highlights the searched character string. For example, the search character string is highlighted by highlighting or coloring.

  Further, the character string search means can search a plurality of character strings, and the document amount visualization means displays a different identification for each searched character string. In this case, the document amount visualizing means identifies and displays a different color for each searched character string, and the document display means highlights the document using the same color as the document amount visualizing means. .

  Preferably, while the mark indicating the search character string is selected (clicked) by the document amount visualizing means, the corresponding character string in the document is highlighted by the document display means and selected by the document amount visualizing means. It is also possible to cancel the highlighting on the document display means at the same time as canceling. If there are many colored parts in the document, it will be difficult to find the corresponding character string. Further, if coloring or selection portions remain, there is a possibility that editing with the document display means becomes difficult due to obstruction. While the text volume is being clicked, the corresponding text in the document is highlighted so that you can easily find the corresponding text. Since the highlighting by means is also canceled, the highlighting does not get in the way during editing.

  Preferably, the information processing apparatus further includes a version management unit that holds a version of the document, and a changed portion extraction unit that extracts a difference between the current document and the previous document, and the document amount visualization unit includes the change The changed part is highlighted and displayed according to the extraction result of the partial extraction means. The changed portion extracting unit extracts differences between documents of a plurality of versions, and the document amount visualizing unit highlights and displays the changed portions for each version. It makes sense to visualize another person's changes, such as when a document is handed over to another person and the other person makes a change and returns. It is also possible to cope with visualization when a plurality of people make changes at the same time. In addition, the following developments are possible. When the mouse cursor is placed on the highlighted change, the previous text (before editing) and the difference from the current are displayed or displayed.

  The document amount visualizing means can also display the document size of the section by a pie chart. Compared to the case where the document size is displayed as a bar graph, the distribution of each section in the document can be grasped more intuitively. Further, by making the document size the size of the pie chart, it is possible to intuitively grasp the difference in the sizes of a plurality of documents. However, pie charts are not suitable for visualizing hierarchical structures compared to bar charts. For this reason, it is suitable for visualizing a single hierarchy document (without a nested section).

  The document amount visualizing means may display the document size of the section by a line graph. Visualization with a line graph has almost the same effect as visualization with a bar graph. The difference is that it is easier to understand the change in the amount of each section. Unlike the case of a pie chart, it is possible to deal with a hierarchical structure, and it is possible to deal with an interaction such as closing a lower hierarchy.

  An information processing program according to the present invention has a function of visualizing a document having a hierarchical structure, and has a document holding means for holding document data, and a document section based on the document data held in the document holding means. Displayed by the hierarchical structure display means capable of displaying the hierarchical structure in a tree structure, the document amount visualization means for quantitatively displaying the document size of the section displayed by the hierarchical structure display means, and the hierarchical structure display means Document display means capable of displaying the corresponding document contents of the section.

  According to the present invention, the document data of the created document is retained, and the hierarchical structure of the section of the document is displayed in a tree structure based on the retained document data, and the document size of the section displayed in the hierarchical structure is displayed. It has a step of displaying quantitatively.

  With the information processing apparatus according to the present invention, the size of an edited or created document can be intuitively grasped hierarchically for each section.

  The document visualization device according to the present invention is preferably implemented in an electronic device such as a personal computer. FIG. 1 is a block diagram illustrating a configuration of a document visualization apparatus according to an embodiment of the present invention. The document visualization apparatus 1 includes an input / output device 10 that inputs data through a keyboard, a mouse, and the like, and outputs data to a printer, a display control unit 20 that performs display control of the display 22, a data memory 30, and a program memory 40, a central processing unit 50, and a bus 60 for connecting each unit. The data memory 30 includes a large-capacity storage device such as a hard disk and a main memory that temporarily stores calculation processing results. The program memory 50 stores various program data, and includes, for example, a program 42 relating to a word processor for creating a document, a program 44 for visualizing a document being edited or created. The central processing unit 50 controls each unit according to the program in the program memory 40 and executes a desired function.

  The document visualization apparatus 1 according to the present embodiment has a basic function for visualizing a sentence as shown in FIG. In the figure, a bar graph corresponding to the length of each section is displayed next to the tree structure of the section heading. A view that displays the hierarchy of the section headings on the left side and the text length of each section as a bar graph (referred to as an outline view for convenience), and a view that displays the entire document on the right side for editing (for convenience) , Called Document View).

  In the outline view, not only the hierarchical structure of the sections of the created sentence but also the bar graph corresponding to the length of each section can be displayed to intuitively grasp the length of each section of the document. It becomes possible. In the example of FIG. 2, all the lower layers are open. In this case, a bar graph corresponding to the total including the lengths of the sentences in the lower layer is displayed lightly in the upper layer (displayed as a dotted line in the figure). .

  For example, in “3. System”, what corresponds to the sentence up to “3.1. Outline” is a solid line, and “3.1. Outline” and “3.2. Details” in the lower hierarchy are combined. Those corresponding to are indicated by dotted lines. The hierarchical structure of the outline view can be closed and opened by operating the mouse.When closed, the dotted line part becomes a solid line, and when opened, the lower-level heading and bar graph are displayed, and at the same time, the upper-level hierarchy is displayed. The solid line part becomes a dotted line. Note that there are some practical parts even though the lower level of “3. System” is open. The text from the end of “3. System” to just before “3.1. In this case, this section corresponds to the introduction corresponding to the section).

  When each section is selected in the outline view, the section is scrolled to the position of the corresponding section in the document view, and the user can view the contents of the desired document.

  Next, an example of visualizing the search result of the sentence being edited using the basic functions of the outline view and the document view will be described. When a character string search is performed on the document being edited, as shown in FIG. 3, the relative position is identified and displayed in the section where the corresponding character string appears. For example, in the bar graph, the color of the position may be changed. In FIG. 3, it is identified by a vertical line L. Details of the character string search function will be described in the following embodiments.

  As a result, it is possible to easily grasp at which position in the entire document the specific character string appears, and further, at which position in which section. Furthermore, the following information can be read from the search example of FIG. First, whether or not the searched character string is used in the whole sentence, and secondly, the searched character string is the first part of “1. Introduction”, the second half part of “2. Background”, “5. It can be seen that it is frequently used at the beginning of the "related research".

  Furthermore, when the user clicks a part identified as a search result in the outline view, the document of the corresponding section is scrolled and displayed in the document view, and the search character string is displayed by coloring or highlighting. To do. This makes it possible to easily grasp the context (context) in which the search character string is used in the sentence.

Such functions are considered useful in the following situations.
(1) There are cases where the character string “document” is defined in which position in the document and how it is referenced. When you edit a document, especially when you move a sentence by cut and paste, you may refer to it before defining a word. When this is avoided, such a function is effective.
(2) When the terms “document” and “document” are used properly in the document depending on the context, this is effective when checking whether each use is correct or not.
(3) When replacing the term “document” in a document with the expression “document” or “sentence” while confirming how it is used, first search for “document” and click on colored parts one after another. While replacing the term "document". At this time, the colored vertical bar in the bar graph also functions as a marker of the current work, and it is possible to grasp "how much work has been done", "how much remains after".

  Next, an example of visualization of an editing history and a changed part will be described. It is also possible to visualize the document editing history and the changed part by the same method as described above. The example of FIG. 4 is an example in which the changed part from the previous version of the document is visualized. For example, it can be seen that the black portion V1 is a changed portion, and the greatly changed portions are in the first half of “1. Introduction”, the second half of “2. Background”, and the second half of “6. Further, the black vertical bar V2 in the first half of “2. Background” indicates that the change is not a large change for each sentence or paragraph, but a small change such as a word or a little expression. Furthermore, there is a hatched rectangle V3 in the latter half of “2. Background”, which shows the deleted portion as an afterimage.

  The version of the document being edited may be one in which the user explicitly designates creation of the version, yesterday's document, last week's document, or one in which the system automatically holds the version of the document. It is also possible to visualize a plurality of versions of a document in the same graph, for example, by reducing the color of the difference from the old version.

  Furthermore, the editing work is not necessarily based on the same person. When a plurality of people are co-authoring a sentence, it is possible to grasp who changed where by visualizing the difference from the editing by others. However, in this case, for example, it is necessary to deal with color coding for each user so that editing can be identified for each user.

  Next, a document visualization apparatus according to an embodiment of the present invention will be described in detail. FIG. 5 is a functional block diagram showing the basic configuration of the document visualization apparatus, and uses the basic functions of the outline view and the document view described above. Each means shown in FIG. 5 can be realized by software, hardware, or both.

  In the figure, data about a document edited by the user is stored in the document holding means 100. The document holding unit 100 holds and manages data in order to visualize the section structure and the block structure according to the document structure. Details of the data structure will be described later.

  FIG. 6 shows a display example when the document is visualized, and the relationship with each means of FIG. 5 is clearly shown therein. The hierarchical structure display means 110 displays the hierarchical structure of document sections like a tree structure based on the document data held by the document holding means 100. Each section heading is displayed with a section number (1, 2, 3,...). “3. System” and “4. Evaluation” have a lower hierarchy, and the lower hierarchy is opened in FIG. In addition, the symbol “-” displayed on the left side indicates that the hierarchy is open. When this symbol is closed, it becomes a “+” symbol, but “1. Introduction”, “2. Background”, etc. do not have a lower hierarchy, so the symbol “+” does not have a symbol “−”. In other words, it corresponds to the outline function of a word processor (“Heading Map” in the case of Microsoft Word).

  The document amount visualizing means 120 displays a bar graph next to the hierarchical structure display means 110 so as to correspond to the length of each section. In the bar graph of each section, each section is blocked into paragraphs. For example, the section “1. Introduction” has three paragraphs, and “2. Background” has four paragraphs. The width of the block on the graph corresponds to the length of the paragraph. The sentence amount visualizing means 120 visualizes the appearance position of a figure, a table, etc. by displaying an icon K such as a circle in the bar graph. It can be seen that the document of FIG. 6 includes three figures and tables. That is, one circle is displayed in the bar graph of “3.1. Overview”, and two circles are displayed in the bar graph of “3.2. Details”. The display position of the circle corresponds to the position existing in the section or paragraph. “3. System” and “4. Evaluation” have lower hierarchies. In FIG. 6, these lower hierarchies are opened. At this time, a graph corresponding to the sum of the sentence amounts in the lower hierarchies is indicated by dotted lines. it's shown.

  The document display means 130 displays the entire document being edited or created. In other words, it has a display function equivalent to that of a normal word processor. A method for composing the entire document will be described later.

  By providing such visualization, the user can intuitively grasp the length of sentences for each section, the structure and length of paragraphs, and the overall image of the appearance positions of diagrams and tables.

  Next, a data structure in the document holding unit 100 will be described. As shown in FIGS. 7, 8, and 9, the document holding unit 100 includes a block table that is a set of blocks, a section table that is a set of sections (each section is configured as a set of blocks), and a hierarchy of sections. Has a section hierarchy table that holds relationships.

  A block corresponds to a paragraph or sentence that constitutes a sentence. The block table shown in FIG. 7 holds a block identifier “block ID”, a “text” that is the contents of the block text, and a “start position” and “end position” in the block document. Here, for the sake of simplicity, the start position and the end position are absolute positions in the document. However, these positions may be relative positions in the section including the block. The latter can reduce the calculation cost in the reconstruction of the document structure accompanying the structure change. This is because if the start position and the end position are held as absolute positions, the position of all blocks must be recalculated when the document structure is reconstructed.

  Sections correspond to the sections and chapters that make up the text. The section table shown in FIG. 8 is an ordered set of blocks including a section identifier “section ID”, a section heading “title”, a section document “start position” and “end position”, and a section. It has a certain “block set”.

  The section hierarchy table is a data structure for holding a section hierarchy. As shown in FIG. 9, it has a “section ID” that functions as a pointer to a section, a “parent section” that indicates the parent of the section, and a “child section set” that indicates an ordered set of children of the section.

  Such a data structure may be tagged from the beginning and stored in a file, or may be constructed in some way when the system reads from the file. Here, it is assumed that the data structure as described above exists.

  Also, when the sentence structure is changed, for example, if the order of the blocks is changed, the order of the blocks in the section is changed, and the start position and end position of all blocks are recalculated accordingly. .

  FIG. 10 conceptually shows the data structure shown in FIGS. The hierarchical structure display means 110 calculates a section number according to the above section hierarchy and presents it to the user together with the section heading.

  The document amount visualizing means 120 calculates the length of the block in the section for each section, and presents the rectangles proportional to the length in a stack to the user. Each section is accessed in a depth-first manner.

  Next, a method for forming a block rectangle for each section will be described with reference to the flowchart of FIG. A block in the section is extracted (step S101), and the length of the text in the block is calculated (step S102). Next, a block rectangle on the GUI is generated in proportion to the text length of each block (step S103). The newly generated block rectangle is placed to the right of the previous block rectangle (step S104), and the generated block rectangle is associated with the block on the data structure (step S105). It is not always necessary to associate the block rectangle on the GUI with the block on the data structure, but by doing so, clicking the block rectangle to move to that position in the document, the block rectangle It is easy and fast to change the document structure by dragging and dropping. For example, in FIG. 6, when the user clicks “3.2 Details” in “3. System”, the corresponding document is displayed on the document display means (indicated by hatching in the figure). ) In this way, the processing from steps S101 to S105 is repeated for all blocks included in each section.

  Next, a document generation method (document text generation method corresponding to a sequence of sections and blocks) in the document display means 130 will be described with reference to the flowchart of FIG.

  In the figure, a method of generating a sentence T displayed by the document display unit 130 will be described. The sentence T is emptied (step S201), and the section S is acquired one after another with priority given to the depth from the data structure of FIG. 10 (step S202). A combination of the section number and title is added to the sentence T (steps S203 and S204). Next, if there are blocks included in the section S, they are taken out one after another (step S205), and the text of each block is added to the sentence T (step S206). This is done for all sections.

  Next, the interaction operation in the present embodiment will be described. In the configuration shown in FIG. 6, the operations of the hierarchical structure display means 110 and the document amount visualization means 120 are different from the above.

  FIG. 13 is an example of visualization in a state where the lower hierarchy is opened. The symbol “-” is displayed to the left of the section heading to indicate that it is open. FIG. 14 shows a state in which the section “3. System” is closed. A symbol “+” is displayed to the left of the section heading to indicate that it is in a closed state. In accordance with the display change in the hierarchical structure display means 110, the display also changes in the document amount visualization means 120. In other words, by closing the section “3. System”, the graph of the lower hierarchy disappears, and instead, the graph of the length corresponding to the total length of the sentences of the lower hierarchy is displayed. . On the other hand, the display of the section “4. Evaluation” in which the lower hierarchy is not closed remains as it is.

  Next, FIG. 15 shows a functional block diagram of the document visualization apparatus according to the second embodiment of the present invention. The second embodiment includes correspondence calculation means 140 in addition to the first embodiment (configuration shown in FIG. 5).

  The correspondence calculation unit 140 calculates the position of the corresponding document from an arbitrary point on the graph in the document amount visualization unit 130. For example, a corresponding document is searched by clicking an icon in the bar graph shown in FIG. The other operations of the hierarchical structure display unit 110, the document amount visualization unit 120, and the document display unit 130 are substantially the same as those in the first embodiment.

  A method of selecting a linkage between the document amount visualizing unit 120 and the document display unit 130 will be described. When an arbitrary point is clicked on the graph of the document amount visualizing unit 120, the document amount visualizing unit 120 displays the length L of the ID rectangle of the clicked section (rectangle) and the rectangle of the clicked point. And the relative position in the horizontal direction are acquired and passed to the correspondence calculation means 140. Correspondence calculation means 140 searches for section S clicked from the section table and acquires it. Then, the absolute position in the document corresponding to the clicked point is calculated by the following equation (1). This corresponds to the position of the document corresponding to a point in the rectangle of the document amount visualizing means 120.

  Next, in the document display unit 130, the text display is scrolled so that the position calculated by the above formula is displayed. Here, there is no block table because the existence of blocks is not assumed. When assuming the existence of a block, it is necessary to obtain the ID of the clicked block and do the same.

  Next, FIG. 16 shows a functional block diagram of the document visualization apparatus according to the third embodiment of the present invention. The third embodiment includes character string search means 150 in addition to the second embodiment (configuration shown in FIG. 15). FIG. 17 shows a visualization example when searching for two character strings “document” and “document” in the document visualization apparatus according to the third embodiment. The portion corresponding to the appearance position in the document is displayed in the graph of the text amount visualizing means 120 as “document” as a red vertical bar and “document” as a blue vertical bar. However, in FIG. 17, since the color cannot be identified and displayed, both are displayed as black vertical bars, but R indicates red and B indicates blue.

  The document display unit 130 highlights the character string in the same color as the bar color of the document amount visualization unit 120 so that the character string can be recognized at a glance. In the figure, the highlight display is indicated by rectangular areas 132 and 134. Thereby, the sentence amount visualizing means 120 can easily grasp where each word is used in the entire document. Furthermore, by coloring the character string by the document display means 130, it becomes possible to easily find a word in the document, and it is possible to easily grasp in what context each word is used. become.

  Further, when the document amount visualizing means 120 is selected by clicking a vertical bar indicating the appearance position of a word, the document display means 130 is scrolled so that the corresponding portion is displayed in the area.

  Next, a modification of the above embodiment will be described. In both the first and second embodiments, the bar graph is used to visualize the outline view, but other visualizations are also possible.

  FIG. 18 shows an example of visualization using a pie chart. The document amount visualizing means 120 visualizes the document amount of each section using a pie chart instead of a bar graph. The pie chart of FIG. 3 does not display lower-level sections or blocks, but of course, they may be displayed by incorporating them into the pie chart. By using a pie chart, you can intuitively understand how much of each section is allocated.

  In the pie chart, the interaction of opening and closing the hierarchy is not shown, but by selecting the heading of the hierarchical structure display means 110, the corresponding segment of the pie chart of the document amount visualization means 120 supports the hierarchical structure. It is possible to perform the display.

  Furthermore, by clicking an arbitrary point on the pie chart, it is possible to calculate the rotation angle in the pie chart and move to a corresponding part of the document in the document display means 130. At this time, whether it is inside or outside the circle has no meaning, and the corresponding position of the document is obtained only by the rotation angle.

  Next, an example of visualization in a line graph is shown below. FIG. 19 shows a portion corresponding to the sum of the sentence amounts in the lower hierarchy with dotted lines for the opened hierarchy. In order to make it easy to understand in the figure, it is overlapped with a bar graph, but it is not always necessary to do so, and only a line graph may be displayed.

  FIG. 20 is a diagram illustrating functional blocks of the document visualization apparatus according to the fourth embodiment. In the fourth embodiment, the version management unit 160 that manages the version of the document data stored in the document holding unit 100, and the change portion extraction that extracts the difference between the current document and the past document and identifies the change portion. Means 170. For example, the version management unit 160 may be one in which the user explicitly designates creation of a version, or may be one in which the creation date and time of a document are managed in chronological order.

  The changed part extracting unit 170 extracts changed parts by comparing documents between a plurality of versions, and sequentially updates them. The changed part includes a newly added part and a deleted part. For example, it is possible to determine which part of a section block has been added or which part of a section block has been deleted.

  Based on the change information held in the changed part extracting unit 170, the document amount visualizing unit 120 can show the changed portions V1, V2, and V3 in a bar graph in the section as shown in FIG.

  Furthermore, the editing work is not necessarily based on the same person. When a plurality of people are co-authoring a sentence, the difference in editing by each person can be visualized by changing the version for each person. Thereby, it is possible to easily grasp who changed where. In this case, the document amount visualizing unit 120 takes measures such as color coding for each user so that the difference for each user can be identified.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific embodiments, and various modifications can be made within the scope of the gist of the present invention described in the claims. Deformation / change is possible.

  In the above embodiment, in order to identify and display the appearance position of the figure / table, the color of the bar is changed, but other than this, it may be displayed with an icon or the like. Similarly, in the character string search, other identification displays such as icons can be used. Furthermore, the graph for visualization by the document amount visualization means may use a display other than a bar graph, a pie graph, or a line graph.

  The document visualization apparatus, program, and method according to the present invention can be used in an electronic device such as a personal computer, and can be used in particular with software having an existing word processor function, an editor, or the like, or independently. . Furthermore, the document visualization device should be interpreted broadly and includes a document visualization system.
