Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hypermedia system and a hypermedia document creating / editing method, and more particularly, to placing a multimedia document on a plurality of cards,
The present invention relates to a hypermedia system that handles a hypermedia document that can dynamically associate information in the document by defining links between the cards, and a method of creating / editing the hypermedia document.

[0002]

2. Description of the Related Art In recent years, there are many tools for displaying or creating hypermedia documents on a computer such as an electronic manual and an electronic book.

Hypermedia documents are characters, moving images,
Multimedia documents that allow mixed audio, images, etc.
Irrespective of the document structure defined by the conventional concept of lines and pages, by arranging the information contained therein on multiple cards, one information can be viewed from related information in multiple directions and other information can be viewed. To provide higher-dimensional information by dynamically connecting with.

At present, such hypermedia documents are not only used for digitizing books such as the above-mentioned electronic manuals and electronic books, but are also being applied to CAI systems and expert systems.

[0005] Such a hypermedia document usually has a stack structure composed of a plurality of cards, and the cards related to each other are linked by some means.

Conventionally, when creating a stack,
The user himself had to define a link button from one card to a card related to that card and associate the cards with each other.

However, since the amount of information is large and the links between the information are complicated, setting the link information is a labor-intensive work. In particular, in the process of creating / editing a hypermedia document, it may be necessary to divide one card in the stack into multiple cards (for example, all the contents of "Chapter 1" are arranged). 1
If you want to logically subdivide one card into "1.1 Chapter", "1.2 Chapter", etc.) and re-create the link button to associate these cards, It is very troublesome and troublesome for the user.

Further, it is necessary to refer to the created hypermedia document while turning the cards one by one by clicking a link button arranged on the card with a mouse or the like. For this reason, when it is desired to switch from a specific card to a related card for display, it may be necessary to flip through a plurality of cards before the target card is reached, and there is a drawback that it takes time to search.

Further, when changing the link structure of a card, there is a problem that the user has to change the link button arranged on the related card.

[0010]

As described above, conventionally, the link between cards must be defined or changed by the user himself, and when creating or editing a hypermedia document, in particular, editing such as card division is required. When doing the work, there was the drawback that a lot of effort was required to redefine the links.

The present invention has been made in view of the above point, and the link redefinition necessary for an operation relating to a link definition for creating or editing a hypermedia document, particularly for performing an editing work such as card division. It is an object of the present invention to provide a hypermedia system and a hypermedia document creating / editing method which are excellent in operability by enabling the work of (1) to be automated.

[0012]

Means and Actions for Solving the Problems
In a hypermedia system for creating / editing a hypermedia document, means for analyzing the logical structure of an input document and creating a logical structure file describing the logical structure, and constructing the input document according to the logical structure file While assigning information to multiple cards,
A means to define a link between those cards to create a hypermedia document, and a split editing means to split the card to be split into multiple cards and redefine the link when a card split is specified by an input command. The division editing means analyzes the logical structure of the text document assigned to the division target card, and logically converts the text document on the division target card into a plurality of text documents according to the analysis result. Means for updating the contents of the logical structure file so as to be divided, and according to the updated logical structure file, the plurality of logically divided text documents are allocated to a plurality of new cards, respectively, and Means for defining a link between each new card and the split target card,
It is characterized in that the card division and the redefinition of the links accompanying the division can be automatically executed according to the logical structure of the text document assigned to the card to be divided.

In this hypermedia system, attention is paid to the fact that the text document included in the input document usually has some logical structure, and the hypermedia document is created and edited based on the logical structure.

That is, in creating a hypermedia document, first, the logical structure of the input document is analyzed, and a logical structure file describing the hierarchical structure of the input document is created according to the analysis result. Then, the input document information is automatically allocated to the cards and the links between the cards are defined in accordance with the contents of the logical structure file, whereby a hypermedia document is created.

When the division / edit processing of the hypermedia document is performed, a command indicating the card division is input by, for example, the user selecting the division function from the edit menu displayed on the screen. In response to this input command, the division editing means that functions as a tool for division processing is executed. The division editing means first divides a text document arranged on a division target card into a plurality of documents logically,
The logical structure is analyzed and the logical structure file is updated according to the analysis result. Then, according to the contents of the updated logical structure file, a logically divided text document is allocated to a new card, and a link between the new card and the card to be divided is defined. It is automatically divided into multiple cards.

Therefore, the operation relating to the link definition for creating or editing the hypermedia document, particularly the link redefining work required when performing the editing work such as card division, can be automated, and the operability is excellent. It can realize a hypermedia system.

Further, in order to simplify the card search operation from one card to another card, the connection relation between a card and all the cards linked to it is set according to the hierarchical structure described in the logical structure file. It is preferable that the screen is displayed by a tree structure, and a desired card can be directly selected from the screen.

With this, it is possible to immediately confirm the link structure of all cards related to a specific card in the hypermedia document, and to directly switch to the target card without flipping the cards one by one from that point. .

Each card has a first link button item indicating a card linked to the lower layer of the card and a second link button indicating a card linked to a lower layer of the card corresponding to the first link button item. The link button item of the first link button item, and the second link button item is more predetermined than the first link button item so that the hierarchical relationship between the first and second link button items is explicitly shown on the card. It is preferable to arrange it in a position indented by a digit.

As a result, the contents of the hierarchical structure can be understood to some extent from one card containing a hypermedia document. Further, it is preferable that the logical structure file is configured to be updated according to the change in the layout relationship between the link button items on the card, and the hierarchical relationship between the cards is changed according to the layout relationship between the link button items. By doing so, for example, when the link button is moved to the right, the contents of the logical structure file can be automatically changed such that the hierarchical structure corresponding to the link button is changed to the next lower level. This makes it possible to easily change / correct the hierarchical relationship between the cards.

The file device 13 is, for example, a secondary storage device of a computer such as a magnetic disk device, in which a logical structure description file 131 and a content file 132 are stored as information necessary for managing a hypermedia document.

The logical structure description file 131 is created as a result of the logical structure analysis of the text document, and is composed of a data group showing the logical structure of the text document. That is, the text document is classified into some document strings by the logical structure analysis, and the logical structure description file 131 is created from the logical structure data created for each document string.

Each logical structure data is composed of a logical structure part, a display / layout part, and a link structure part. In the display and layout section, format information for outputting a document on paper is set. Also, the logical structure part stores media information such as the media type of the corresponding document string and the content file name in which it is stored, and the link structure part links to other document strings related to the corresponding document string. Information and reference structure link information are set. The link information of the reference structure defines the link relationship with the image information or the like referred to in the document string.

The content file 132 holds the substance of a structured text document sequence and image information referred to in the text document sequence. Input / output management of the logical structure description file 131 and the content file 132 is performed using an object-oriented database. Since the object-oriented database encapsulates data and its procedure as objects, it is possible to handle various different media forming a multimedia document with a common operation message.

The structured editor 14 is a system that supports efficient document creation. The structured editor 14 has a logical structure analysis unit 141, and generates the logical structure description file 131 and the content file 132 according to the analysis result of the text document by the logical structure analysis unit 141. Also, this structured editor 1

The stack editing section 151 is for performing processing such as editing a stack composed of a plurality of cards and changing the contents thereof.
The links between the cards created in 2 are defined according to the contents of the logical structure description file 131.

The card layout section 152 arranges objects (including text information, link buttons, titles, etc.) on a card, which is a basic unit of display, to create a card. The card layout section 152 includes various functions for card creation (editing such as division, font designation,
The size is specified), and each of these functions is executed by the user selecting the corresponding icon on the menu bar displayed on the screen with the mouse or the like.

The logical structure updating unit 153 updates the logical structure description file 131 so that the hierarchical relationship between the card and another card is changed in response to a change in the arrangement of link buttons on the card. The logical structure extraction unit 154
Information indicating a link relationship between a card and all cards related thereto is extracted from the logical structure description file 131. This extracted information is displayed in a window as a tree structure by an icon.

The card display unit 155 displays a card, a menu bar, etc. on the screen of the display monitor. Also, the card display unit 155 and the logical structure extraction unit 154
Provides a multi-level link button display function. This function is a function to display not only the card one level below the card but also a link button indicating a card of an arbitrary hierarchical level on a card at the same time.

FIG. 2 shows a basic procedure for converting an input document into a hypermedia document in the hypermedia system shown in FIG. The document is a "chapter",
It consists of "sections" and "paragraphs". In the logical structure analysis of the structured editor 14, keywords for expressing the logical structure, such as “Introduction” and “Chapter 1”, are extracted from a normal document created by a word processor or the like, and a “title” is given for each sentence. , Logical attributes such as “chapter heading” and “paragraph” are determined.

Further, a hierarchical tree structure as shown in the figure is created based on the result, and finally the logical structure description file 131 and the content file 132 are created.

The content file 132 is a substance of structured document information, and the content files 132 are created by the number of document information classified by structuring, that is, the number of nodes in the tree structure. In this case, the created content files 132 are numbered in a structured order.

The logical structure description file 131 is referred to by the hyper editor 15, and according to the contents of the logical structure description file 131, a plurality of linked cards (stacks) corresponding to the tree structure of the document are created as shown in the figure. To be done.

FIG. 3 shows an example of the form of a card created by the hyper editor 15. As shown in the figure, each card is composed of a title area 201, a paragraph area 202, and a link button area 203 arranged on the card mount. The title area 201 serves as the title of the card itself, and the content of the "headline" of the document corresponding to the card is placed here. In the paragraph area 202, the body part of the paragraph corresponding to the “heading” is arranged. The link button area 203 is an area for defining a link with another card, in which the title of the linked card is placed.

Next, with reference to FIG. 4, a specific description will be given of how a document structured in a tree structure is assigned to a card. Here, as shown in FIG. 4 (A), the document is classified into three nodes, which are composed of headings "Introduction", "Specifications", and "Summary" and paragraphs subordinate thereto. Suppose that.
In addition, in the paragraph of “specification”, a figure is referred to in the text, whereby the reference part (text) and the reference body (figure) referred to by the reference part (text) are combined.

The document structured as shown in FIG.
It is converted into a stack as shown in FIG. This stack is composed of a table of contents card C1, a card C2 corresponding to a node (first), a card C3 corresponding to a node (specification), and a card C4 corresponding to a node (collective).

The table-of-contents card C1 is created in order to immediately call the target card.
In 1, the headings of all cards (here, cards C2 to C4) are centrally managed.

That is, the card C1 is used as the table of contents card C1.
And three cards C2 to C4 are respectively linked to three link buttons L1 to L3. The link button L1 has the heading "Introduction" of the linked card C2 and the link button L2 has the link The heading "Specification" of the link destination card C3 and the heading "Summary" of the link destination card C4 are respectively arranged as labels on the link button L3. Further, in the specification card C3, a link button L4 for realizing a reference link with a drawing is assigned, and "drawing" is arranged as a label there.

Each of these cards also holds a link (bidirectional) to the linked card, and can return from the link destination to the link source. Further, according to the route (contents card C1, card C2, card C3, card C4, contents card C1), it also holds a link to the next card. The data structure of each of these cards C1 to C4 is shown in FIG.
Shown in

As shown in FIG. 5, each card includes title information, text information, and link button information. For the table of contents card C1, title information and text information are undefined, and for the link button information, a pointer and a script (go to “Introduction”) for linking with the card C2, and a link with the card C3. Pointer and script (go to
"Specification"), and a pointer and a script (go to "end") for linking with the card C4 are defined.

Regarding the card C2, the link button information is undefined, and the title information of "Introduction" and the body information including the pointer indicating the content file holding the text document corresponding to "Introduction" are defined. .

For the card C3, the title information of "specification" and the body information including the pointer indicating the content file holding the text document corresponding to the "specification" are defined, and the link button information includes the content in the body. A pointer and a script (go to “figure”) for linking with an external file holding the figure referred to by are defined.

For the card C4, the link button information is undefined, and the title information of "End" and the body information including the pointer indicating the content file holding the text document corresponding to "End" are defined. ing.

As described above, in the hypermedia system shown in FIG. 1, a card link is automatically defined in accordance with the result of structural analysis of the document to create a hypermedia document.

Next, the editing function of the hypermedia system shown in FIG. 1 will be described with reference to FIGS. FIG. 6 shows an edit screen provided by the hypermedia system of FIG. 1, FIG. 7 shows the procedure of the split edit process, and FIG. 8 shows the logical structure changed by the split edit and the corresponding stack. It is shown.

The operation of division editing will be described below by exemplifying the case of dividing the specification card C3 of FIG. 4 (B). The instruction to execute the card dividing function is displayed on the screen as shown in FIG. 6 with the card to be divided (specification card C3 in this case).
Is displayed, the edit icon 102 is selected from the menu bar 101 on the screen by mouse operation or the like to display the edit function submenu, and the split function is selected from the submenu by mouse operation or the like. Be done.

As a result, the command for instructing division is shown in FIG.
Is sent from the input unit 11 to the hyper editor 15 and the card dividing process is performed as follows in accordance with the procedure of FIG. First, the text document arranged on the card C3 currently displayed on the screen, that is, the text document regarding the specifications in the content file 131 (here, including specifications 1 and 2) is input to the logical structure analysis unit 141. , The logical structure of the text document is analyzed (step S101). In this case, the card C3 has "specifications"
Since all the contents of "Specification" are contained, the text document of "specification" is logically divided into two text documents of "specification 1" and "specification 2."

Then, based on the analysis result, the contents of the logical structure description file 131 are changed from FIG. 4 (A) to FIG.
The logical structure information is changed to that shown in FIG.
102).

Next, the updated logical structure data section is referred to by the stack editing section 151, and the logically divided text documents are arranged in new cards respectively.
Further, the link is redefined according to the logical structure information (steps S103 and S104).

As a result, the specification card C3 is shown in FIG. 8 (B).
Card C corresponding to the text document of "Specification 1" such as
31 and a card C corresponding to the text document of "Specification 2"
32 and 32. The heading "Specification 1" of the corresponding text document is used as the title of the card C31, and the heading "Specification 2" of the corresponding text document is also used as the title of the card C32.

Since the figure is referred to in the text document of the specification 2, a reference link button for linking with the reference figure is arranged on the card C32. Furthermore, in the original card C3, link buttons L12 and L13 for linking with the card C31 of specification 1 and the card C32 of specification 2 are arranged.

As described above, in this embodiment, when division editing is requested, the logical structure of the text document arranged on the card to be divided is logically divided into a plurality of documents. It is automatically analyzed, and the logical structure description file 132 is updated according to the analysis result. Then, according to the updated logical structure, a logically divided text document is allocated to a new card, and a link between the new card and the card to be divided is automatically defined. As a result, one card can be divided into a plurality of cards without the user making a link creating operation.

Next, referring to FIGS. 9 and 10, FIG.
The tree structure window display function realized by the logical structure extraction unit 154 and the card display unit 155 will be described.
This function is to display the connection relation between a card and all the cards linked to it in a window structure with a tree structure so that the desired card can be selected and displayed directly from the window.

FIG. 9 shows how the display screens are switched, and FIG. 10 shows the procedure for displaying the tree structure window. The tree structure window display function will be described below by taking the case where the display card is switched from the table of contents card C1 to the specification 2 card C32 in the stack having the link relationship as shown in FIG.

When the link button L2 having the "Specification" label is selected while the table of contents card C1 is displayed as shown in FIG. 9A, the card display section 155 causes the logical structure extraction section 154 to operate. All logical structures linked to the lower hierarchy of the specification card C3 are extracted from the logical structure description file 131 (step S201), and this is displayed as a window in a tree structure (sup S202).

In this case, as shown in FIG. 9B, the display screen displays a window W1 in an area different from the table of contents card C1, and the windows W1 are linked by a tree structure. The button is displayed.

In this state, when the link button L23 having the label of specification 2 is selected from the displayed tree structure, the card C32 is called by using the pointer information defined in the link button L23. , The display is switched from the contents card C1 to the specifications 2 card C32 as shown in FIG. 9C (steps S203 and S204).

Therefore, it is possible to immediately confirm the link structure of all cards related to a specific card in the hypermedia document, and to switch the display directly to the target card without flipping the cards one by one from that point. It will be possible.

Next, with reference to FIGS. 11 and 12, the multi-layer link button display function realized by the logical structure extraction unit 154 and the card display unit 155 of FIG. 1 will be described.

FIG. 11 shows the display state of the multi-level link button, and FIG. 12 shows the procedure for displaying the multi-level link button. Hereinafter, a case where a multi-layered link button is displayed on the table-of-contents card C1 in a stack having a link relationship as shown in FIG.

When the multi-layered link button display function is specified from the input unit 11 by the user's keyboard or mouse operation, the logical structure extraction unit 154 causes the logical structure description file 131 to display the currently displayed contents card C1. The hierarchical structure up to the first level and an arbitrary level designated by the user is read (step S30).
1). The card display unit 155 extracts only the heading from the extracted hierarchical structure and defines the extracted heading as the label of the link button (steps S302 and S30).
3).

Therefore, when only the display up to the first row is designated, only the link buttons L1 to L3 of "Introduction", "Specifications" and "Summary" are displayed on the table of contents card C1 as shown in FIG. 11 (A). Although it is displayed, when the display up to the second row is designated, as shown in FIG. 11B, in addition to the link buttons L1 to L3, the heading of the two cards C31 and C32 in the lower layer of the specification card is displayed. Link buttons L2 'and L2''labeled with are also displayed.

Further, in this case, since the first-stage link button and the second-stage link button have different hierarchical levels, the second-stage link button L is clearly indicated as such.
2 ′ and L2 ″ are arranged at positions indented by a predetermined digit from the first-stage link buttons L1 to L3.

If a card is created and edited using this multi-layer link button display function, the contents of the hierarchical structure can be understood to some extent from one card containing a hypermedia document, and cards of lower levels for many layers can be obtained. It is also possible to switch the display directly to.

Next, the logical structure changing function for automatically changing the corresponding logical structure by moving the link button on the card will be described with reference to FIGS. 13 and 14. FIG. 13 shows a state from the movement of the link button to the update of the stack structure by changing the logical structure, and FIG. 14 shows the procedure for changing the logical structure. The logical structure changing operation when the specification link button L2 on the table of contents card C1 is moved in the stack having the link relationship as shown in FIG. 8 will be described below.

The arrangement position of the specification link button L2 on the table-of-contents card C1 is moved to the right as shown in FIG. 13 (A) to FIG. 13 (B) and moved down one character by the user's mouse docking operation. When changed to the open position, the card layout unit 152 recognizes the change contents of the link button to be changed and the logical structure related to the link button (step S401).

For example, when the link button L2 is moved to the right as described above, the card C3 corresponding to the link button L2 is changed to a card one level lower than the card C2. recognize. The card layout unit 152 sends this information to the logical structure update unit 153.
The logical structure update unit 153 to update the contents of the logical structure description file 131 (step S402).

Further, the card layout section 152 automatically changes the link buttons according to the updated logical structure, and arranges the link button L21 for linking with the specification card C3 on the card C2 as shown in the figure ( Step S404). This changes the stack structure of the hypermedia document.

As described above, by changing the layout of the link buttons in the order or indentation on the card, the link button connection is automatically updated.

Next, the logical structure changing function for automatically changing the corresponding logical structure by moving the link button on the card will be described with reference to FIGS. 13 and 14. FIG. 13 shows a state from the movement of the link button to the update of the stack structure by changing the logical structure, and FIG. 14 shows the procedure for changing the logical structure. The logical structure changing operation when the specification link button L2 on the table of contents card C1 is moved in the stack having the link relationship as shown in FIG. 8 will be described below.

By the user's racking operation of the mouse or the like, the arrangement position of the specification link button L2 on the table of contents card C1 is moved to the right as shown in FIG. 13 (A) to FIG. 13 (B) and lowered by one character. When changed to the open position, the card layout unit 152 recognizes the change contents of the link button to be changed and the logical structure related to the link button (step S401).

For example, when the link button L2 is moved to the right as described above, the card C3 corresponding to the link button L2 is changed to a card one level lower than the card C2. recognize. The card layout unit 152 sends this information to the logical structure update unit 153.
The logical structure update unit 153 to update the contents of the logical structure description file 131 (step S402). Further, the card layout unit 152 automatically changes the link buttons according to the updated logical structure, and arranges the link button L21 for linking with the specification card C3 on the card C2 as illustrated (step S40).
4). This changes the stack structure of the hypermedia document.

In this way, by changing the layout of the order of the link buttons on the card or changing the layout such as indentation, the link button reconnection is automatically updated.

As described above, in the hypermedia system of this embodiment, attention is paid to the fact that the text document included in the input document usually has some logical structure, and the hypermedia document is based on that logical structure. Is created and edited, an existing document created by a word processor or the like can be read as an input document from a disk or the like, and it can be easily converted into a hypermedia document.

Further, by analyzing the logical structure of the text document arranged on the card to be divided and updating the logical structure file 132 according to the analysis result, 1
It is also possible to automatically divide one card into multiple cards.
