Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an explanation function of an expert system.

[Conventional technology]

An expert system is a computer system that uses the knowledge of experts as a knowledge base and uses reasoning functions to solve problems in the same way as experts.

In addition to displaying the conclusion obtained through inference, an expert system must also explain the process leading to the solution of the problem and the basis for the decision. It is provided.

[Problem to be solved by the invention]

By the way, in the explanation function of conventional expert systems, the only explanations that can be displayed regarding the inference process are declarative knowledge (facts) about a certain object, and this explanation is displayed using text information. It was only. Therefore, when referring to image information related to an object, it is necessary to provide a separate output/means for each fault. Moreover, since a detailed explanation of the image information was not displayed, there was a problem in that it was difficult to understand the relationship between the explanatory text and the image information.

SUMMARY OF THE INVENTION An object of the present invention is to provide an expert system that can insert image information into an explanatory text of declarative knowledge and easily display an explanatory text regarding the image.

[Means to solve the problem]

In order to solve the above problems, the expert system according to the present invention inserts image information into the output of an explanation consisting of text information, and also combines the image information and another declarative knowledge related to the image information. Image information control means is provided for associating explanatory text, for example, performing bitmap control.

[Effect]

Image information is inserted into the explanatory text by specifying a variable to which the image information is bound, and at the same time is associated with the object in the explanatory text. When the image information inserted in the explanatory text is selected using a pointing device, etc., the object associated with the image information is searched, and the explanatory text associated with that object is used as the explanatory text of the selected image information. Output.

〔Example〕

An embodiment of the expert system according to the present invention will be described below.

FIG. 1 is a block diagram showing the configuration of a workstation for realizing an expert system according to the present invention.

In FIG. 1, the processor unit 1 inserts a bitmap image (hereinafter referred to as a bitmap), which is image information, into the explanatory text, and also stores information about the bitmap and other declarative knowledge related to the bitmap. It is composed of an image information control means 2 for associating explanatory texts, an inference engine 3 for making inferences, and an explanation function 4 for explaining the results of the inferences. Note that this processor section 1 is composed of peripheral circuits centered on a CPU (central processing unit).

The input/output section 5 includes a display 6 as a display means, a bitmap memory 7 for the screen corresponding to each dot on the display 6, a keyboard 8 for inputting text information for explanation, etc., and a keyboard 8 for inputting text information for explanation, etc. a mouse 9 which is an input instruction means for instructing bitmaps and bitmaps; and a keyboard/mouse control section 1 which controls input/output of commands and data inputted from the keyboard 8 and mouse 9.
It is composed of 0.

The storage unit 11, which is a storage means, includes a disk 12 in which a knowledge base is stored, a disk control unit 13 that controls input and output of data on the disk 12, and commands and data input from the operating system and input/output unit 5. ,
and a main memory 14 in which a text editing editor and the like are stored.

Note that the processor section 1, input/output section 5, and storage section 11
are commonly connected to a system bus 15 consisting of a plurality of buses for controlling data, addresses, and the like.

Next, the operation for inserting a bitmap into an explanatory text using a text editing editor will be explained based on FIGS. 2 to 6.

FIG. 2 shows the editor editing the explanatory text of the instance "Missionary and Cannibal." A title bar menu (not shown) is displayed in this editor, and the user selects an item from the menu that he or she wishes to execute.

Here, select “InsertBitmap” from the menu.
Object", a sub-window 21 for input opens above the editor, as shown in Figure 3. The user writes the object name here. If the written object actually exists, A message prompting you to enter the slot name will be displayed.In this example, we have entered the object name "Missionary" which already exists as a class, so as shown in Figure 4, you will be prompted to enter the slot name. Please enter" message is displayed in the sub-window 21. Note that if you write an object name that does not exist as a class or instance, an error message will be displayed.

If no slot name is input in the state shown in FIG. 4, the object itself and the bitmap are associated. Further, when a slot name is input and the slot/slot exists, the pair of object name and slot name is associated with the bitmap.

Also, if a slot name that does not exist is written, an error message will be displayed.

Next, as shown in Figure 5, the message "Please enter the bitmap variable name" appears in the subwindow 2.
1, the user specifies the variable bound to the bitmap. Here, 'missionary-bitmap' is input as the variable name. If the input variable represents a bitmap, the bitmap of the missionary input by the user is displayed on the editor as shown in Figure 6. and associated with the object.

When you have finished editing, select aSave & close from the editor's title bar menu with the mouse,
The explanatory text of the instance "Missionary and Cannibal" is saved in the disk 12 or main memory 14.

The processing procedure of the processor unit 1 when inserting a bitmap into an explanatory text using the text editing editor described above will be explained based on the flowcharts of FIGS. 7 and 8.

In Figure 7, first select 'In' from the editor menu.
When "sertBitmapObject" is selected (
Step 101), a subwindow for manual operation is opened above the editor (step 102), and it is determined whether an object name has been written (step 103). Here, when the object name is written, it is determined whether the object exists or not in step 104.
), if it exists, displays a message in the subwindow to prompt the input of the slot name (step 105).
.

Next, after displaying the subwindow in step 105, it is determined whether one or more characters of the slot name have been input (step 106). Here, if one or more characters of the slot name are input, it is determined whether the slot exists (step 107). If a slot exists, the pair of object name and slot name is associated with the bitmap (step 108), and the bitmap is specified (step 109). Further, in step 106, if one or more characters are not input for the slot name, the object itself is associated with the bitmap (step 110), and the bitmap is specified (step 109).

In step 109, the subroutine shown in FIG. 8 is called and a bitmap is specified. To specify a bitmap, there are two ways to specify the bitmap:
There are two types: one is not specified, and the other is to specify the variable name manually in the subwindow.

First, it is determined whether a variable name has been entered in the subwindow (step 201), and if the variable name has been entered manually, a bitmap is specified from the input variable J (step 201).
Step 202). On the other hand, if the bitmap is not specified using the LISP method, an arbitrary area on the display is specified without inputting a variable name (step 203). In this case, the specified area on the display is displayed as a bitmap.

When the bitmap specification is completed, the process returns to the main routine again and it is determined whether the specified bitmap exists (step 111). Here, if a bitmap exists, the specified bitmap is inserted at the caret position of the editor (step 112).

Note that if the object specified in step 104 does not exist, the slot specified in step 107 does not exist, or the bitmap specified in step 111 does not exist, an error message is displayed (step 113).

Next, the operation for displaying the explanatory text regarding the image inserted in the explanatory text will be explained based on FIGS. 9 and 10.

Figure 9 displays the explanatory text for ``Missionaries and Cannibals''. Inserted into this description are bitmaps representing missionaries and cannibals.

Here, when the cannibal bitmap is selected with the mouse, an explanatory text regarding the class "cannibal" is output as shown in FIG.

Next, the processing procedure of the processor section 1 when displaying the explanatory text regarding the above-mentioned image will be explained based on the flowchart of FIG. 11.

First, when a bitmap in the explanatory text is selected with the mouse (step 301), the object and slot values are obtained by referring to the fields of the bitmap data (step 302). Then, it is determined whether the object actually exists (step 303), and if it exists, it is determined whether there is a descriptive text associated with the object or the slot of the object (step 303).
Step 304). Here, if there is a descriptive text,
The bitmap is assigned and the associated explanatory text is output (step 305). Also, in step 303,
If the object does not exist, an error message is displayed (step 306), and if the explanatory text does not exist in step 304, the process ends.

In the embodiment described above, the data regarding the bitmap in the 0 editor, which uses a hash table as a means for associating the bitmap with the explanatory text, has object and slot values as fields. When you click a bitmap in the editor with the mouse, the hash table is searched using the object and slot values as keys to find the file name where the explanatory text is stored and the address where the data is stored in the file. Then, the disk is searched using the file name and address, and the desired explanatory text is retrieved.

〔Effect of the invention〕

As explained above, in the expert system according to the present invention, image information is inserted into the output of explanatory text, and the image information is associated with an explanatory text of another declarative knowledge related to the image information. Therefore, when the image information in the explanatory text is selected on the screen, the explanatory text related to that image information can be easily displayed. It is easy to understand the relationship between
