[Detailed Description of the Invention] <Industrial Application Field> The present invention is applicable to, for example, the construction of an extractor stem,
Building qualitative simulation models of social phenomena,
It relates to editing methods when editing acquired knowledge on the screen in information organization management, problem solving, idea support, implication determination (any subject matter is acceptable), etc.

<Conventional technology> Editing the unedited knowledge acquired and creating a knowledge base in the construction of expert systems, qualitative simulation models of social phenomena, information organization management, problem solving, ideation support, decision making, etc. The following functions are required when converting into a system. In other words, it is a knowledge editing support function that edits and structures acquired unedited knowledge and expresses it on the screen with simple operations, making it possible to edit knowledge more accurately by visually appealing it. is necessary.

Therefore, in response to such needs, recently we have developed a system that simply displays cards, arrows, spread notes, etc. on the screen.
Many editing methods have been proposed for editing and managing knowledge (information) using diagrams.

<Problem to be solved by the invention> When unedited knowledge obtained through interviews with experts etc. is turned into a knowledge base, or when unorganized knowledge is organized using the KJ method for the purpose of problem solving or implication determination. requires the following: That is, in the above-mentioned case, the number of unedited knowledge obtained is large to some extent. Therefore, when assembling this large amount of knowledge data from the bottom up, it is necessary to make a correspondence between the entire structure of knowledge that has already been structured up to a certain point and the partial structure of the knowledge that is to be structured at that point. It is necessary to proceed with the structuring work while checking the following.

However, in editing methods that simply display cards, arrows, spread notes, etc. on the screen and edit and manage knowledge using diagrams, the following problems arise due to limitations on the size of the display screen. . In other words, when assembling a relatively large amount of knowledge data from the bottom up, there are constraints on the screen size, so it is necessary to display the overall structure of the knowledge and the partial structure to be structured on the same screen. I can't. Therefore, there is a problem in that it is not possible to advance the structuring of knowledge while taking correspondence between the overall structure and the partial structure of structured knowledge.

Therefore, the purpose of this invention is to graphically display structured knowledge of a certain size on a display screen of limited size by simple operations. The present invention aims to provide an editing method that can efficiently edit a large-scale graphical net while taking correspondence between the overall structure of the graphical net and its partial structure on the display screen.

Means for Solving the Problems To achieve the above object, the present invention provides a method for creating a graphical net in which relationships between items are graphically structured and expressed using cards, arrows, etc. means, a graphic display means for displaying the graphical net on a display screen, and an editing means for editing the graphical net displayed on the display screen, while viewing the graphical net displayed on the display screen, In an editing method that allows editing of unedited items input from an input means or the graphical net, the display contents of the display screen are displayed as an entire display screen displaying the overall structure of the graphical net and a partial structure of the graphical net. a screen switching means for switching between a partial display screen and a partial display screen; and displaying a position on the entire display screen corresponding to the content of the partial display screen using a window opened on the entire display screen, and displaying the position on the entire display screen corresponding to the content of the partial display screen; A corresponding window display means that moves on the entire display screen according to instructions, and when the window is moved to another position on the entire display screen, the content of the graphical net in the above at the position after the window is moved is displayed in the above part. A large-scale graphical net can be edited efficiently by providing partial display means for enlarging and displaying on the display screen, and switching between a partial display screen and the entire display screen of the graphical net on the same display screen. It is characterized by the fact that

A graphical net in which relationships between items are graphically structured and expressed using cards, arrows, etc. is created by the graphical net creation means and displayed on the display screen by the graphic display means. At that time, the display content of the graphical net displayed on the display screen by the graphic display means described in 2. You can switch to the displayed partial display screen.

When the display contents of the display screen are switched to the whole display screen, the position on the whole display screen corresponding to the contents of the partial display screen is displayed in a window opened on the whole display screen by the corresponding window display means. be done. In this case, when the input means instructs to move the window, the corresponding window display means moves the window to another position on the entire display screen in accordance with the window movement instruction. Then, the contents of the graphical net in the window after moving on the entire display screen will be
The partial display means enlarges and displays the partial display screen -L. Then, the partial structure of the graphical net displayed on the partial display screen is edited by the editing means.

Therefore, according to the present invention, the entire display screen and the partial display screen of the graphical net can be switched and displayed on the same display screen, and the contents of the partial display screen and the contents of the entire display screen can be associated with each other. can be displayed.

Figure 2 shows an example of a display in a normal state (display state 'Q when no special display is instructed from the input means 1), and the work screen WS is a partial display screen PS (enlarges the specified partial structure of the graphical net). screen) is being displayed. When a partial display screen PS is displayed on the work screen WS, it is not possible to edit graphic objects (specific individual shapes to be edited that constitute a graphical net) in the partial display screen PS. It can be done. Examples of graphical objects edited in the partial display screen PS include cards 21, 22, 23, and 24 on which knowledge content is written as shown in FIG. There are arrows 26, 27, and 28 attached. The graphical net is created by the input means 1 and stored in the object storage means 9 as described above.

FIG. 3 shows a state in which only the partial display screen PS is called up and displayed on the work screen WS as shown in FIG.
This shows the screen of the display device when calling. In this case, the entire display screen AS becomes the partial display screen P.
It is displayed superimposed on S. When calling the entire display screen AS, the area displayed on the partial display screen PS is displayed as a [window JMD] opened in the entire display screen AS.

FIG. 4(a) shows the movement of the window JMD in the entire display screen AS in FIG. 3. In FIG. 4(a),
``The window JMD can move freely on the entire screen AS, for example, by following the mouse, which is the input means 1, as shown by the arrow (A). The content displayed in the JMD (that is, the partial structure of the graphical net) changes to the content of the "window JMD" move destination. As a result, the "window JMD" at the moved position changes.
The partial structure of the graphical net within is displayed on the partial display screen PS of FIG. 3 as shown in FIG. 4(b). Also,
If you fix the window JMD on the entire display screen AS, you can edit the contents of the window JMD at that position (i.e., the partial structure of the graphical net displayed on the partial display screen PS). The size of the window frame 31 when AS is called is fixedly displayed regardless of the movement of the window JMD. Also, the partial display screen PS that is partially displayed in FIG. As shown, it is possible to recall the display screen of only the partial display screen PS.

FIG. 5(a) shows a virtual screen Is necessary for determining the positional relationship between the partial display screen PS, the entire display screen AS, and the window frame 31 shown in FIG. This virtual screen Is is a rectangular area containing the entire structure of the current graphical net.
It is displayed in the same size as the partial display screen PS in FIGS. and 3.

As shown in FIG. 5(b), the entire display screen AS is the graphical object displayed on the virtual screen Is reduced to the size of the frame 32 in FIG. 3. When the entire display screen AS of FIG. 5(b) is displayed superimposed on the partial display screen PS of FIG. 2, the screen of FIG. 3 is obtained. Further, an area 33 in FIG. 5(a) represents an area currently displayed on the partial display screen PS.

That is, the area 33 corresponds to the "window" MD of the entire display screen AS, and the positional relationship of the area 33 on the virtual screen Is corresponds to the positional relationship of the "window jMD" on the entire display screen AS in FIG. , area 33 of the virtual display screen zS
The contents within correspond to the contents displayed on the partial display screen PS.

The editing method of this invention displays a second image on the screen of the display device.
The partial display screen PS shown in the figure and the entire display screen AS shown in FIG. 3 are switched and displayed to see the correspondence between the overall structure and the partial structure of the graphical net. If necessary, as shown in Figure 4, move the "window JMD" on the entire display screen AS to fix the partial structure of the graphical net that you want to edit, and then
The user switches to the partial display screen PS displaying the partial structure of the graphical net to be edited in the diagram, and edits this partial structure of the graphical net.

Hereinafter, the editing operation will be explained in detail according to the screen display examples shown in FIGS. 2 to 5.

First, the entire display screen AS is called from the partial display screen PS shown in FIG. 2 to display the screen shown in FIG.

(2) Display procedure for the entire display screen AS FIG. 6 is a flowchart of the entire display screen display operation. Hereinafter, the display procedure of the entire display screen AS will be explained according to FIG.

In step St, input means! When the display of the entire display screen AS is instructed from the keyboard, the screen switching means 3 of the display means 2 is called by the control means 11. Then, a screen switching operation is executed by this screen switching means 3.

In step S2, the size of the area in which all the graphical nets can be displayed on the virtual screen Is in the memory space of the object storage means 9 that stores the graphical nets (hereinafter referred to as the temporary size of the virtual screen Is) is determined in detail later. It is determined in this way. Then, image data is read from a location corresponding to the temporary size of the virtual screen [S in the object storage means 9, and the virtual screen Is is displayed.

In step S3, the size of the entire display screen AS and the size of the virtual screen [S (same size as the size of the partial display screen PS)]
From this, the virtual screen ■S shown in FIG. 5(a) is converted to FIG. 5(b).
Figure reduction ratio when reducing to the entire display screen AS shown in ■
) is calculated.

In step S4, the size of each graphic object of the graphical net on the virtual screen Is is reduced according to the graphic reduction ratio P calculated in step S3, and the display size of the graphic object on the entire display screen AS is calculated. be done.

Then, according to the calculated display size of the graphic object on the entire display screen AS, the entire display screen A
Graphic display means 4 shows individual graphical objects in S.
displayed by.

Next, an example of a method for determining the temporary size of the virtual screen Is carried out in step S2 will be described in detail.

In this method of determining the temporary size of the virtual screen Is, first, the vertical and horizontal sizes of all the graphical objects on the graphical net are determined from the leftmost, oldest, top, and bottom coordinates of all the graphical objects on the graphical net. calculate. Next, a correction term is added to any of the vertical and horizontal dimensions of all the graphical objects so that the calculated vertical and horizontal size ratio of all the graphical objects becomes equal to the vertical and horizontal size ratio of the entire display screen AS. , calculate the sizes of all temporary graphical objects whose vertical and horizontal size ratios are equal to the vertical and horizontal size ratios of the entire display screen AS.

Then, add vertical and horizontal margins to the size of this temporary figure object and create a virtual screen! Determine the tentative size of S.

Namely, a virtual screen! Temporary size of S (W: width, H height)
is determined as follows in FIGS. 5(a) and 5(b).

xl - Leftmost X coordinate of the leftmost graphic object Yl - Topmost Y coordinate of the top graphic object X2 - Oldest X coordinate of the oldest graphic object X2 - Bottom Y coordinate of the bottom graphic object WA - Width of the entire display screen AS 1 (A - Height of the entire display screen AS MX - Margin in the width direction of the virtual screen MY - Margin in the height direction of the virtual screen PA - (Y2 - Yl) / (X2 - Xi )PD=HA/W
If A WD=X2-XI HD=YL-Yl, then WD (PA/PD)+2XMX =-(PA>PD)
HD+2XMY-(P
A>PD) When the contents of the graphical net stored in the object storage means 9 in the temporary size W, H of the virtual screen Is calculated in this way are displayed in the same size as the partial display screen PS, the virtual screen It becomes Is.

That is, when the display of the entire display screen AS is instructed, the read range of the memory space of the object storage means 9 that stores the graphical net is automatically determined, the virtual screen Is is displayed, and the virtual screen IS1. : Based on the entire range of graphical nets, the entire display screen AS
is displayed.

Next, an example of a method for calculating the figure reduction ratio P calculated in step S3 will be described in detail.

The graphic reduction ratio P is the ratio between the size of the entire display screen AS and the size of the virtual display screen Is.

That is, the figure reduction ratio P is determined as follows.

When WA=width of the entire display screen AS WC=width of the virtual screen is, when the virtual screen Is is reduced and displayed using the graphic reduction ratio P calculated as P=WA/W, the entire display screen AS is It becomes.

In this way, the entire display screen AS is displayed on the display means 2, such as a display device, according to the flowchart of FIG. Then, based on the displayed entire display screen AS, the partial display screen PS is cut out and displayed as follows.

■ Procedure for cutting out partial display screen PS FIG. 7 is a flowchart of a partial display screen cutting operation in which the partial display screen PS is cut out by operating window JMD on the entire display screen AS. The procedure for cutting out the screen PS will be explained.

In step Sll, window display is selected.

In step S12, the size of the window frame 31 is determined as follows using the figure reduction ratio P calculated in step S3 of the flowchart of FIG.

That is, as described above, the virtual screen Is in FIG. 5(a)
An area 33 in is an area currently displayed on the partial display screen PS. Therefore, when the frame of the area 33 of this virtual screen Is is reduced by the graphic reduction ratio P, it becomes a window frame 31 of the "window" MD as shown in FIG. 5(b). Therefore, based on the coordinates of the frame of the area 33 on the virtual screen Is (that is, the coordinates around the area currently displayed on the partial display screen PS on the virtual screen Is) and the figure reduction ratio P, Coordinates on the entire display screen AS corresponding to each coordinate on the frame are calculated. The window frame 31 is a series of coordinates on the entire display screen AS corresponding to each coordinate on the frame of the area 33.

In step S13, the window frame 31 is displayed by the graphic display means 4 at the coordinates on the entire display screen AS that correspond to the coordinates on the frame of the area 33 on the virtual screen Is calculated in step S12. This will be the initial window frame.

In step S14, the coordinate data of the initial window frame on the entire display screen AS is stored in the storage means 8 in preparation for calling up the initial partial display screen.

In step SI5, window frame operation is selected by the input means 1. Then, the mouse, which is the input means 1, is moved to move the window frame 31 on the entire display screen AS.

In step S16, at the mouse position moved in step SI5, a graphics operation such as exporting a figure using XOR is used to erase the previously displayed window frame, and at the same time A window frame 31 is displayed.

In step 817, the position of the window frame 31 displayed in step S16 is confirmed, and it is determined whether the position is to be fixed. As a result, if the mouse is not fixed, the process returns to step S15 and the mouse is further moved. Below, depending on the mouse movement, the window frame 3 will be moved until the mouse movement is finished.
I is repeatedly crossed out. On the other hand, if the position of the window frame 31 is to be fixed, the process advances to step S1B.

In step S18, the window frame 31 is fixed to the position confirmed in step S17, and this fixed window frame 3
A partial structure of a graphical net within 1 is displayed on a partial display screen PS.

The display of the partial structure of the graphical net on the partial display screen PS is executed as follows.

That is, in the virtual screen Is shown in FIG.
3. Is there a bitmap that is the intersection of two bitmaps: the bitmap of the "window JMD compatible" on the entire display screen AS and the bitmap of the graphical object (that is, does the area 33 overlap the area of the graphical object)?
The object search means 6 sequentially searches each graphical object to determine whether or not the object is a graphic object, as will be described in detail later.

In step 819, based on the bitmap of the intersection set searched and determined in step S18,
A partial display screen PS of the graphical net at the position of the destination window JMD is displayed by the graphic display means 4.

By doing this, the entire display screen AS and the partial display screen PS of the graphical net can be switched and displayed on the screen DS of the display device, and the entire structure and partial structure of the graphical net can be displayed on the entire display screen AS through the window jMD. You can deal with this. Also, the entire display screen A
[Move windows JM and D on S to change the partial structure of the graphical net displayed on the partial display screen PS, and display the required partial structure of the graphical net on the partial display screen PS.
It can be displayed on the screen.

Furthermore, when the position of the window frame 3t is fixed, a screen in which the partial display screen PS and the entire display screen AS shown in FIG. When the screen is switched by the screen switching means 3, the partial structure of the graphical net displayed on the partial display screen PS can be edited by the object changing means 7 using a known method.

Next, the search for the bitmap of the intersection of the bitmap of the area 33 on the virtual screen Is and the bitmap of the graphic object, which is performed by the object search means 6, will be described in detail.

In this search, first, the larger value of the leftmost X coordinate of the area 33 and the leftmost X coordinate of the graphical object to be searched is determined to be the same as the oldest X coordinate of the area 33 and the target. If the value is smaller than the smallest of the oldest X coordinates of the graphic object, it is assumed that the area 33 and the target graphic object overlap in the X coordinate direction. Next, the larger value of the lowest X coordinate of the area 33 and the lowest X coordinate of the target graphical object is
If it is smaller than the smaller value of the topmost X coordinate of the area 33 and the topmost X coordinate of the target graphical object, it is assumed that the area 33 and the target graphical object overlap in the X coordinate direction. .

Therefore, when the above two conditions are satisfied, the area 33
It is assumed that the object and the target graphical object overlap.

That is, (ML, MT) - upper left coordinates of area 33 (MR, MI3
) = Lower right coordinates of area 33 (L, T) - Upper left coordinates (1, 8) of the graphic object - Lower right coordinates of the graphic object, then M A XL = max (M L , L ) M
Calculate I Nn=min (MR, R) MAXT=max (MB, B) MI NB-afn (MT, T), and calculate M A
If L<M I N R and MAXT<MT NB are satisfied, it is assumed that a bitmap of the intersection of the bitmap of the area 33 and the bitmap of the graphic object exists.

For example, in FIG. 5(a), the graphic object 34
In the case, MAX L = max(M L , L +) = L
M I NR=min(MR,R,)=R.

MA X T =llax(MB,Bt)=B
+MINB=min(MT,T,)=T.

L,<R,,', MAXL<MINRAlso, B,<
T, ,', MAXT<MINB Therefore, there is a bitmap of the intersection set of the two bitmaps of the area 33 and the graphical object 34, and a part of the graphical object 34 in the area 33 is displayed in the graphic display means 4 according to the bitmap of this intersection set. can be displayed on the partial display screen PS.

In addition, in the case of the graphic object 35, MAX L=
max(ML, Lt)-1-wMINR=min(MR

Execute such a search for all shape objects,
A graphical object overlapping the area 33 (that is, a partial structure of the graphical net within the window JMD in the entire display screen AS) is displayed on the partial display screen PS.

As described above, in the editing method of the present invention, when editing the partial structure of the graphical net by displaying the partial display screen PS on the screen of the display means 2 such as a display device, the When displaying the correspondence between the partial structure and the whole structure, input means 1 such as a keyboard
Input instructions for the entire display screen AS from . Then,
By the screen switching means 3, the reading range of the memory space of the object storage means 9 which stores the graphical net so that all graphical objects of the graphical net already structured at the present time or the whole display screen AS is automatically read out. The entire display screen AS is superimposed on the partial display screen 1) S and is switched and displayed. At that time, the area of the partial structure of the graphical net displayed on the partial display screen ps is displayed on the entire display screen A5-1- as "
Displayed as window JMD.

In addition, if it becomes necessary to edit other graphical objects of the graphical net while looking at the entire display screen AS, use the input means l to move the window JMD on the entire display screen AS. Then, by using the screen switching means 3 to return the entire display screen AS to the partial display screen PS, the necessary graphic object can be displayed on the partial display screen PS.

That is, according to the present invention, the entire structure and the partial structure of a graphical net can be switched and displayed on a screen of limited size by a simple operation. Therefore, it is important to check whether the position of the partial structure of the graphical net that you are currently editing in relation to the overall structure is correct, or to which substructure of the overall structure of the graphical net the knowledge that you are currently editing corresponds to. You can check it by displaying it on the second screen. Then, while looking at the overall structure of the graphical net, you can quickly call up the required substructure and edit that substructure in detail.

The algorithm for calculating the figure reduction ratio P obtained when the virtual screen IS is reduced to display the entire display screen AS is not limited to the algorithm in this embodiment. Also, the virtual screen above! The algorithm for searching the bitmap of the intersection of two areas, the area 33 and the graphic object area in S, is not limited to the algorithm of this embodiment.

In the above embodiment, a keyboard and a mouse are used as the input means 1, but the invention is not limited thereto.

<Effects of the Invention> As is clear from the above, the editing method of the present invention changes the contents of the display screen on which the graphical net is displayed from the entire display screen to the display screen based on the screen switching means, the corresponding window display means, and the partial display means. a partial display screen, and display a position on the entire display screen corresponding to the content of the partial display screen by a window that is opened on the entire display screen and moves according to an instruction from the input means, and displays the entire display screen. The content of the graphical net in the window after moving the second part can be enlarged and displayed on the partial display screen, so
The entire display screen and the partial display screen of the graphical net are switched and displayed on the same screen, and unedited items or graphical nets are displayed while making correspondence between the overall structure and the partial structure of the graphical net through the window. Can be edited.

Therefore, according to the present invention, a large-scale graphical net can be edited efficiently using a display screen of limited size.
