Abstract

PURPOSE:To provide a document processor which displays the intimacy degree of relation and which can show the whole image of an editing state in the processing of a document so that it is easily understood. CONSTITUTION:A document structure management means 104 associatively manages a node (logical unit), a link (relation describing unit) and intimacy degree decision information for deciding the intimacy degree of the link (the display state of the node of a link destination, time lapse from final access to the link or the like). An intimacy degree decision information change means 1071 updates intimacy degree decision information in accordance with the rise of a prescribed event. A relation intimacy degree calculation means 108 decides relation intimacy degree based on intimacy degree decision information. A construction plan generation means 109 arranges graphic elements showing the node and the link and makes document structure into a graphic. At the time of making the graphic, the display form of the graphic elements of the link is changed in accordance with relation intimacy degree. Since relation intimacy degree is displayed in document structure which is made into the graphic, the editing state of the document can easily be grasped when it is viewed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus which handles a document structure formed by associating predetermined constituent units.

[0002]

2. Description of the Related Art Generally, a document can be expressed as a structure in which logical information units such as chapters, paragraphs and figures are combined. The structure of a document used in normal document processing is a tree structure composed of logical information units.
In a tree-structured document structure, the relationship defined between logical units is an inclusion relationship. For example, in the document structure shown in FIG. 4, a relationship that "1 chapter includes 1.1 section" is defined between 1 section and 1.1 section.

In recent years, without being limited to inclusion relations,
A document processing apparatus has been developed which handles a document structure formed by defining various types of relationships between logical units. These devices are called hypertext systems, and the documents they handle are called hypertext. Hypertext is generally represented as a more flexible network structure than a tree structure. In hypertext, a unit of logical information is called a node and a unit of describing a relation is called a link, and nodes of various types can be freely associated with each other by various kinds of links. Since the hypertext has a flexible structure, it is applied not only to the conventional document processing frame but also to various fields such as multimedia. For hypertext, for example, Jakob Nielse
n, "HYPER Text & HYPER Me
dia "(1991), HBJ Publishing Bureau".

An example of a simple hypertext system is shown in FIGS. The document structure is a network structure composed of nodes and links as shown in FIG. In this example, the links describe reference relationships, which are indicated by arrows in FIG. For example, the relationship “node A refers to node B” is described in this document structure. The information held by the node is shown in FIGS.
It is displayed in each window shown in (c), (d) and (e). The button in the window shows the access point for the link. By pointing a button in the window with a pointing device such as a mouse, a window for displaying the node related by the link can be opened. For example, by pointing the button "node B" shown in the window (a) displaying the contents of the node A, the window (b) displaying the contents of the node B is opened. In the window (b), the button "Node D"
Is displayed, and a window (d) displaying the contents of the node D can be further opened.

Although the hypertext document has a flexible structure, it has a drawback that it is difficult for a user to understand the whole structure. Therefore, in the hypertext system, a device that displays the structure in an easy-to-understand manner plays an important role. Such devices are commonly referred to as browsers and are described in detail in the above references. The most common browsers show a node as a rectangle enclosing a name and a link as a line segment, and a diagram as shown in FIG. 5 is displayed on the screen. By using the browser, the user can understand the whole picture of the hypertext document.

As described above, in hypertext,
Different types of links can be used to describe different relationships between nodes. In some browsers, different types of links are displayed using different graphics to improve the user's understanding. For example, in FIG.
In the browser shown in (2), two types of links are indicated by a solid line and a broken line, respectively.

By the way, when a document is written using the hypertext system, pieces of information are displayed in pieces, which makes it difficult to understand the connections between them. Regarding the nodes A, B, and C in FIG. 5, the relation between the nodes can be known by the display on the browser and the button display in the window in FIG. 6, but the relation between the contents of each node cannot be known.

[0008] Therefore, when displaying a node by pointing a button in the window, a device has been devised which, instead of displaying the node in a different window, embeds it as a subwindow in the window displaying the node. . This device is called an outline editor. For example, as shown in FIG. 8, it is possible to open a subwindow displaying a node C in a window displaying a node A and edit the contents in association with each other. it can.

[0009]

In the example shown in FIG. 8,
You can select the way to display the referenced node by pointing the button. That is, node C can choose to display in the window of node A and node B outside. The display state of this node is
It may be necessary to know the status of the editing work at that time. In particular, if the node displayed internally as a subwindow has a stronger relationship than the node displayed externally, and if this relationship is used to control another process, grasp the display state. The need increases. For example, when the allocation process is performed as a document, the content of the node displayed inside is added to the text and the node displayed outside is used as a comment.

However, in general, windows on a screen may be hidden by overlapping each other, so that the display state cannot always be understood only by looking at the screen. In addition, the above-mentioned browser can easily grasp the whole picture by showing different figures when the types of links are different, but the display state of the node shows how the node referred to is opened. The information is determined only by the information and does not depend on the type of link. Therefore, it does not show the display state of the node on the browser. in this way,
In the prior art, there is no method for indicating the display state of the hypertext in an easy-to-understand manner, and it is extremely difficult to grasp the state of editing work.

The present invention has been made to solve such a problem, and displays the strength of the relationship between nodes,
It is an object of the present invention to provide a document processing device capable of clearly showing an overall image of an edited state in document processing.

[0012]

In order to solve the above problems,
The document processing device of the present invention is a logical unit that is a unit of logical information, and a relation description unit that defines a relationship between the logical units,
And a document structure management means (104) for managing a document structure configured by, and further managing the relationship description unit and the strength determination information necessary for determining the strength of the relationship defined by the relationship description unit in association with each other. , Strength determination information changing means (107) for setting or changing the strength determination information according to the occurrence of a predetermined event, and relationship strength for determining the relationship strength using the strength determination information held in association with the relationship description unit The calculation means (108) and the graphic element representing the logical unit and the graphic element representing the relational description unit are arranged to visualize the document structure, and the form of the graphic element to display the relational description unit in the diagram is shown. And a structural diagram creating means (109) for making a decision based on the relationship strength calculated by the relationship strength calculating means. Further, according to an aspect of the present invention, in the information processing apparatus having the above-described configuration, the strength determination information changing unit accompanies the occurrence of an event in which the user changes the display state of the logical unit referred to by the relationship description unit. The strength determination information is set or changed.

[0013]

A document handled by the document processing apparatus of the present invention has a document structure formed by associating predetermined constituent units.
The information representing the document structure includes a logical unit that is a logical unit of information and a relation description unit that defines the relationship between the logical units. These logical units and relational description units are
For example, it corresponds to the nodes and links in the above-mentioned conventional hypertext. The present invention is further characterized by the fact that the strength determination information necessary for determining the strength of the relationship description unit and the relationship defined by the relationship description unit has been introduced, which is one of the features that is not present in the conventional example. An example of the data structure of the logical unit is shown in FIG. 2A, and an example of the data structure of the relationship description unit including the strength determination information is shown in FIG. 2B. In the example of FIG. 2B, the “display state of the reference node”, which is the display state of the logical unit of the reference destination referred to by the logical unit, is included in the information of the relation description unit as the strength determination information. Each information of the logical unit, the relation description unit, and the strength determination is managed by the document structure management means. The strength determination information is set or changed by the strength determination information changing means each time a predetermined event occurs. The predetermined event corresponds to, for example, the user changing the display state of the logical unit. Taking hypertext as an example, strength determination information is displayed each time the user instructs the referenced node to display in a window or subwindow, or to stop displaying the node. The “display state of the reference node” in 2 (b) is updated. The structural diagram creation means determines the form of the graphic element based on the relationship strength calculated by the relationship strength calculation means by the relationship strength calculation means when generating the graphic element expressing the relationship description unit. Figure 11
Shows an example of the relationship strength. In this example, the strength determination information is the display state S of the link destination node, and the relationship strength is 1 when the display state S is S = CLOSE (not displayed). Relationship strength 2, when S = OPEN (displayed in the window), S = SUBWINDOW
When (displayed in the sub window), the relationship strength 3 is defined. So, for this example,
The relation strength calculating means checks the “display state of the reference node” S included in the link information, and determines the relation strength corresponding to S by referring to the above definition. As an example of the graphic element representing the relationship strength, as shown in FIG. 11, the relationship strength 1 is a broken line, the relationship strength 2 is a thin solid line, and the relationship strength 3 is a thick solid line. The correspondence between the strength and the form of the graphic element is defined. The structural diagram creating means refers to this definition to determine the display form of the graphic element corresponding to the relationship strength, and creates a structural diagram as shown in FIG. 10B, for example.
By looking at this structure diagram, it is possible to easily grasp the whole image even when the editing work is in a state where the windows displaying the documents are overlapped and it is impossible to grasp the whole at once. It will be possible. As described above, according to the present invention, the strength determination information related to the reference description unit is updated according to a predetermined event, the relationship strength between the logical units is determined according to the strength determination information, and the relationship strength is represented. Since the form of the graphic element is determined and the document structure is illustrated, it is possible to easily show the overall image of the edited state in the processing of the document.

(Data structure of the embodiment) FIG. 2 (a),
(B), (c), and (d) show the respective data structures of nodes, links, node graphics, and link graphics.
As shown in FIG. 2A, a node is a “node identifier” uniquely given to the node, a “node name” that is a name given by the user for recognizing the content data held by the node, a node It is composed of a "link list", which is a list of identifiers of links for referring to the node, and "content data" such as character strings and figures. Note that if the node does not reference any other node, the linked list will be empty.

As shown in FIG. 2 (b), the link indicates the "link identifier" uniquely given to the link, the "reference node" which is the identifier of the node referred to by the link, and the state of the window displaying the reference node. The value shown is CLOSE,
It consists of "display state of reference node" that takes one of the values of OPEN and SUBWINDOW, and "window identifier" that is the identifier of the window that displays the reference node and is empty if the reference node is not displayed. Has been done.

The node graphic is, as shown in FIG.
A "figure identifier" that is uniquely assigned to a node figure,
It is composed of a "corresponding node" which is an identifier of a node corresponding to the node graphic and "arrangement coordinates" which is a coordinate value at which the node graphic is arranged.

The link graphic is, as shown in FIG.
"Graphic identifier", which is an identifier uniquely given to the link graphic, "corresponding link", which is the identifier of the link corresponding to the link graphic, and "line thickness", which is the value indicating the line thickness of the link graphic , A coordinate value at which the base of the link graphic is arranged, and a coordinate value at which the tip of the link graphic is arranged.

FIG. 3 shows an example in which the hypertext illustrated in FIGS. 5 and 6 is represented by nodes and links having the above-mentioned data structure.

(Operation of Embodiment) The document processing apparatus of this embodiment uses the display state of the node referred to by the link as the strength determination information, and calculates and obtains the strength of the relationship each time the strength determination information is changed. The document structure display device illustrates the strength of the relationship in the link by changing the shape of the graphic element representing the link according to the value obtained.

FIG. 9A shows an example of creating a document structure diagram based on the display state of the nodes shown in FIG. 8 by the apparatus of this embodiment. In the example shown in FIG. 9A, the display state of the node referred to by the link is not displayed (CLOSE) or is displayed in the window (OPE).
N), displayed in the sub window (SUBWIN
DOW), and the relationship strength is calculated by this state. Such strength determination information may be stored in a specific place, or may be calculated each time a need arises. Further, the calculation result of the relationship strength may always match the strength determination information. That is, in the example shown in the table of FIG. 11, as the strength determination information, CLOSE, OPEN, SUBWINSOW
You can use the values 1, 2, and 3 instead of the value. By looking at this structure diagram, it can be understood that the contents of the node C are displayed in the sub-window in the window displaying the contents of the node A and the like.

The processing of each part in this embodiment will be described below. First, the user specifies the button displayed on the window, opens the menu shown in FIG. 8D, and selects an item to open a window displaying the reference node of the link corresponding to the button. Open
Or close. A window that opens the node as a subwindow if you select Open Externally, opens the node as a subwindow if you select Open Internally, or a window that displays the node if you select Closed. Close the sub window. At this time, the value indicating the display state of the node is stored as the strength determination information of the selected link. OPE when "Open to the outside" is selected
N, if you select "Open inside", SUBWINDOW
When W or "close" is selected, the value CLOSE is stored. When the display state of the node is changed, the document structure diagram is updated. The process of updating the document structure diagram starts from the root node of the predetermined document structure, traces the reference relationship between the node and the link, and arranges the node graphic representing the node and the link graphic representing the link Create a new structural diagram of and display it. At this time, the relationship strength calculation process is performed when the link graphic is generated, and the link graphic having the line thickness corresponding to the obtained value is generated. The relationship strength calculation process calculates the relationship strength based on the definition of the relationship strength shown in FIG. That is, the numerical value corresponding to the display state of the node becomes the value of the relationship strength.

In this embodiment, the entire structure diagram is created every time the display state of the node is changed, but when the display state of the node is changed, the node is referred to from the previously created structure diagram. A method of extracting the link graphic corresponding to the link to be changed and changing the line thickness of the link graphic based on the new relationship strength may be used. In addition, the link holds not only the strength determination information but also the value of the relationship strength, the relationship strength calculation processing is performed at the time of the strength determination information change processing, and the structure diagram is created only when the value of the relationship strength is changed. I do not care.

Although the strength of the relationship is indicated by the thickness of the line segment in the present embodiment, the strength of the relationship may be expressed by the density of the broken line as shown in FIG. 9B. Link (1)
The fact that the density of the broken line is higher in the order of (2) and (3) indicates that the strength of the relationship is higher in this order. In addition to this, color intensity, color type, and the like may be used. Further, the figure showing the strength is not limited to the line segment.

When a plurality of links refer to one node, a plurality of figures showing nodes are prepared and a structural diagram is created so that the figure showing links and the figure showing nodes are one-to-one. In this case, the strength of the relationship may be expressed by the shape of the node graphic. In FIG. 9C, the thickness of the line segment of the node figure indicates the strength of the relationship. In this example, the node D is referred to by the nodes B and C, but is displayed by the access from the node C in the window. This information is not associated with node D and is therefore not displayed as node D information.

In the present embodiment, the relationship strength is defined only by the display state of the node, but other scales may be used together. For example, the time elapsed since the last access to the link may be used for calculating the relationship strength. In this embodiment, the relationship strength is 1 when the node is not displayed, which is the minimum, but the strength is further reduced according to the time elapsed since the node was last accessed from the link, and the line segment is further increased accordingly. May be thin. Furthermore, the graphic indicating the referenced node may not be displayed when the reference time has elapsed.

Further, by using expressions of a plurality of relationship strengths together, the relationship strengths on a plurality of scales may be shown. In the example shown in FIG. 10A, the thickness of the line segment is (1)
(2) It becomes thinner in the order of (3), but the density of the broken line becomes higher in the order of (3), (1), and (2). For example, the thickness of the line segment can represent the display state of the node, and the density of the broken line can indicate the time elapsed since the last access. Figure 10
From the display of (a), it can be seen that the node C is displayed in the window of the node A, but it has not been used recently.

As a method of expressing the change in the shape of the link, not only the drawing parameters such as the thickness of the line segment and the density of the broken line are changed, but also the shape of the line segment is selected from those prepared in advance. It may be decided by a thing. For example, in FIG. 11, the relationship strength 1 is a broken line 2
Is displayed by a solid line and a thick solid line graphic element, a document structure diagram as shown in FIG. 10B is presented.

Next, the node display creation processing by the node display processing means 105 will be described with reference to the flowchart of FIG. As described above, the user specifies the button displayed on the window, opens the menu shown in FIG. 8D, and selects an item to display the reference node of the link corresponding to the button. Open or close. FIG. 12 shows the details of the processing in that case. Step (0) Click the button in the window with the input means 101. Step (1) The link selecting means 102 selects a link corresponding to the clicked button. Step (2) Obtain the link data of the selected link from the link management means 1042. Step (3) A menu as shown in FIG. 8D is displayed, and the user specifies an item on the menu and selects a process. Then, step (4) and step (41)
By, "Open outside""Openinside""Close"
Find out which one was selected. If "Open to the outside" is selected, step (40)
If the reference node is closed by (400 to 403), processing for opening it in the window is performed. If "Open in" is selected, step (41)
0) (4100 to 4103), if the reference node has already been opened, the process ends as it is, and if it has closed, a process for opening it in the window is performed. If "close" is selected, steps (410) (410)
0 to 4103), if the reference node is already closed, the process ends as it is, and if it is not closed, a process for closing the window is performed. Hereinafter, each case will be described in detail.

Step (4) It is determined whether or not "open to the outside" is selected. Step (40) As a result, when it is determined that “Open to the outside” is selected, the value of the “reference node display state” item of the link data having the data structure of FIG.
It is determined whether or not it is LOSE. Step (400) The determination in step (40) is yes.
, That is, the "display state of the reference node" is CLOS
When E, the value of the "reference node display state" is OPE
Change to N. Step (401) Obtain the reference node data from the node management means 1041. Step (402) Create a window for displaying the data in the "content data" section of the obtained node data. Step (403) The display means 111 displays the created window. Then, the process proceeds to step (5) to call the structure diagram creation process 1 (FIG. 13) described later,
The node display processing ends. In addition, in the determination in step (40), the “reference node display state” of the link data is C
If it is not LOSE, the reference node is already displayed, and the process ends.

Step (41) If "Open to the outside" is not selected in Step (4), it is checked whether "Open to the inside" is selected. Then, when the selection is "open inward", the following processing is performed. Step (410) It is determined whether or not the value of the item “display state of reference node” in the link data is CLOSE. Step (4100) The judgment at step (410) is y.
If es, that is, the "display state of the reference node" is CL
When OSE, the value of "display state of reference node" is set to SUB
Change to WINDOW. Step (4101) Obtain data of the reference node from the node management means 1041. Step (4102) Create a window displaying the content data of the node. Step (4103) The window created immediately below the selected button is arranged as a subwindow. As a result, as shown in FIG. 8A, for example, the node B referred to by a certain node A is displayed as a subwindow of the node (A). Then, the process proceeds to step (5) to call the structure diagram creation process 1 (FIG. 13) described later,
The node display processing ends. Also, step (410)
If the “display state of reference node” of the link data is not CLOSE in the determination of No., the reference node has already been displayed, and the process ends.

Step (411) It is judged whether or not the display state of the reference node of the link data is CLOSE. If the display state is CLOSE, the reference node has not been displayed yet, so the node display process is terminated. Step (4110) If the display state of the reference node is not CLOSE in step (411), the display state of the reference node is changed to CLOSE. Step (4111) Then, the window corresponding to the window identifier held by the link data is deleted.
Then, the process proceeds to step (5), the structure diagram creation process 1 (FIG. 13) described later is called, and the node display process ends.

The structural drawing creating process 1 by the structural drawing creating unit 109 will be described with reference to the flowchart of FIG. Step (10) Obtain the data of the root node from the node management means 1041. Step (11) Generate a node graphic corresponding to the node. Step (12) Place the node graphic at the default position. Step (13) Extract the link identifier from the link list of the node and call the structure diagram creation process 2. At this time, the link identifier is passed to the structure diagram creation process 2. Step (14) It is determined whether or not there are unprocessed links. If any remain, the process returns to step (13) to process the remaining ones. If not, the structure diagram creation process 1 is terminated, and the process returns to the process of the program that called the structure diagram creation process 1.

The structure diagram creating process 2 by the structure diagram creating means 109 will be described with reference to the flowchart of FIG. Step (20) Obtain link data from the link management means 1042. Step (21) Call the relationship strength calculation process described later for the link. Step (22) A link graphic having a line segment thickness corresponding to the relationship strength obtained by the relationship strength calculation processing is generated. Step (23) Obtain the data of the reference node of the link from the node management means 1041. Step (24) It is determined whether or not the node graphic corresponding to the reference node already exists. Step (240) As a result of the determination, if the node graphic already exists, the root overlaps the right end of the node graphic corresponding to the reference source node and the leading end overlaps the left end of the node graphic corresponding to the reference destination node. After arranging the link graphic, the flow returns to the flow of the process for calling the structural diagram creation process 2. Step (241) When the determination result of step (24) is negative, a node graphic corresponding to the reference node is generated. Step (242) The node graphic is arranged at a predetermined distance based on the arrangement position of the node graphic corresponding to the reference source node. Step (243) The link graphic is arranged so that the root overlaps the right end of the node graphic corresponding to the reference source node and the tip overlaps the left end of the node graphic corresponding to the reference destination node. Step (244) The reference node determines whether or not the link is held. Step (2440) If the reference node holds a link, the link identifier is extracted from the link list and the structure diagram creation process 2 is called. At this time, the link identifier is passed to the structure diagram creation process 2. Step (2441) It is checked whether there are any unprocessed links remaining. If there are still unprocessed links, the process of step (2440) is repeated for that process. Return to the process that called the creation process 2.

An example of the relationship strength calculation processing by the relationship strength calculation means 108 will be described with reference to the flowchart of FIG. In this example, steps (30) and (301)
The display status of the referenced link destination node is CLOSE
Or OPEN or SUBWINDOW, and the value of the relationship strength is determined by referring to the definition of the relationship strength determination information in FIG. 11 according to the result. Step (30) It is determined whether or not the display state of the reference node of the given link data is CLOSE. Step (300) If the result of the determination is CLOSE, 1 is returned as the value of the relationship strength, and the process returns to the structure diagram creation processing 2 that called the relationship strength calculation processing. Step (301) As a result of the judgment in Step (30),
When the display state of the reference node is not CLOSE, it is checked whether the display state of the reference node of the given link data is OPEN. Step (3010) The display state of the reference node is OPE.
If N, then 2 is returned as the value of the relationship strength. Step (3011) The display state of the reference node is OPE.
If it is not N, that is, if it is SUBWINDOW,
Returns 3 as the value of the relationship strength.

[0036]

As described above in detail, according to the present invention, the strength determination information related to the reference description unit is newly introduced, and the strength determination information is updated according to the occurrence of a predetermined event. Therefore, it is possible to manage the document structure that promptly reflects the change in the editing state due to a predetermined event. Further, since the relationship strength between the logical units is determined according to the strength determination information and the form of the graphic element representing the relationship strength is determined to plot the document structure, the overall image of the editing state in the processing of the document is timely. It is easy to understand.
