Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a knowledge editor for creating knowledge data in a so-called expert system.

[Background Art] An expert system is a system that utilizes the knowledge of experts as knowledge data and provides expert-level information through inference.

As an expert system, for example, JP-A-62-2
The one described in Japanese Patent No. 93354 is known. This system is a system that creates knowledge data from input data according to so-called production rules and performs inference.

That is, an expert operates an interactive input terminal and
Input data according to production rules with hen grammar. For example, if the condition (i
A message indicating that f) and conclusion (then) should be input is displayed (display of a rule template), and the expert inputs data of parameters (rule parameters) related to the conditions and conclusion accordingly. The system assigns the input rule parameter data to the rule template and creates knowledge data.

Here, the rule template refers to a basic pattern of conditions and conclusions. For example, it corresponds to a pattern or a rule template such as "When conditions A and B are met, use equipment C."

For such a rule template, the rule parameter data input by the expert is A.

B and C.

Furthermore, a plurality of rule templates can be prepared, and one rule template can be repeatedly used to create a plurality of knowledge data.

[Problems to be Solved by the Invention] Conventional expert systems have had problems in that inputting rule parameter data is time-consuming and error-prone.

That is, input of rule parameter data must be performed in a predetermined order according to the displayed rule template. In other words, input must be made according to the grammar of the production rules. For this reason, if a person who is not accustomed to input operations performs the input operation, it will take a very long time, or if the input operation is performed without a sufficient understanding of the grammar, there is a possibility that human error may occur.

In addition, if more than a certain amount of knowledge data has been created,
Another problem is that it becomes difficult to modify, confirm, or verify the knowledge data that has been created.

That is, knowledge data is obtained by substituting rule parameter data into a rule template, and even if, for example, the same rule template but different rule parameters are input, separate knowledge data will be created. As a result, it has become necessary to handle a huge amount of knowledge data, making it inefficient and difficult to modify, confirm, and verify the knowledge data. Specifically, the need to modify, confirm, and verify the knowledge data causes trouble when the knowledge data is displayed on the screen of an interactive input terminal or printed out.

The present invention was made with the aim of solving these problems, and it is an object of the present invention to accurately manually input rule parameter data using simple manual operations without requiring knowledge of grammar or proficiency in manual procedures. The purpose is to make it possible to easily modify, confirm, and verify input data.

[Means for Solving the Problems] In order to achieve such an object, the knowledge editor of the present invention includes a template input section that inputs information related to a rule template from an input terminal to create rule template data, and a template input section that creates rule template data. A rule template database for storing rule template data, a means for importing rule template data from the rule template database, a means for displaying rule parameter items in the imported rule template data on an input terminal screen, and input/output of rule parameter data. a parameter input unit having means for displaying rule parameter data on the screen of an input terminal in alignment with the item display; a rule parameter database for storing input rule parameter data; A knowledge data editing section that creates data.

[Operation] In the knowledge editor of the present invention, first, information related to a rule template is inputted from an input terminal by the template input unit, and rule template data is created. The created rule template data is then stored in the rule template database.

The stored rule template data is read out by the parameter input section. Furthermore, the rule parameter items included in the read rule template data are
displayed on the input terminal screen. Furthermore, the rule parameter data that has already been input is read out from the rule parameter database and displayed in line with the item display, that is, in a table format. The user, the expert, operates the input terminal while viewing such a display and inputs rule parameter data through the parameter input section.

The input rule parameter data is then stored in the rule parameter database. Further, the knowledge data editing section creates knowledge data from the rule template data and the rule parameter data.

In this way, in the present invention, inputted rule parameter data is displayed in a table format, thereby simplifying the work of inputting, modifying, and confirming/verifying rule parameters. Furthermore, since the input procedure is simplified, familiarity with grammar and input skills are not required, and erroneous input is prevented.

[Examples] Hereinafter, preferred embodiments of the present invention will be described using the drawings.

FIG. 1 shows the configuration of an expert system using a knowledge editor according to an embodiment of the present invention.

The expert system 10 shown in this figure includes a wisdom editor 12 that edits and creates knowledge data according to this embodiment, and a knowledge database 1 that stores the created knowledge data.
4, and an inference unit 16 that executes inference regarding input data using knowledge data and outputs the result.

That is, the knowledge data created by the knowledge editor 12 is stored in the knowledge database 14 and is used in the inference by the inference section 16.

The knowledge editor 12 includes a template input unit 20 that inputs rule template data from the input terminal 18, and a rule template database 22 that stores the rule template data.
Parameter input section 2 for inputting rule parameter data from
4, a rule parameter database 26 that stores rule parameter data, and a knowledge data editing section 28 that edits knowledge data from rule template data and rule parameter data.

The operation of the knowledge editor 12 according to this embodiment will be explained in more detail below.

In this embodiment, when a user wants to create knowledge data, it is necessary to set a rule template in advance. Input of this rule template is performed by the user's operation of the input terminal 18.

First, the user operates the input terminal 18 to input data related to a rule template, that is, rule template data. The rule template data in this embodiment has a structure as shown in FIG. 2, for example.

In this figure, the rule template data consists of a rule name section 100, a Japanese expression section 102, a rule template section 104, and a parameter definition section 1.6.

The rule template section 104 is a section that describes a rule template, which is a basic pattern of knowledge data, according to if-then rules. The rule name section 100 is a section that describes the name of the rule written in the rule template section 104, and the Japanese expression section 102 is a section that describes the rule template in Japanese.

In the description of the Japanese expression section 102, rule parameters are indicated by symbols such as <A> and <B>. The attributes of the rule parameters related to these symbols are determined by the parameter definition unit 10.
6. Further, the number of rule parameters is approximately 5 to 6 per rule template.

A user (in this case, often the designer/producer of the system) inputs rule template data having such a configuration by operating an input terminal. The template input unit 2o stores the input rule template data in the rule template database 22. The amount of rule template data that can be stored is approximately 20 rule templates.

The rule template data input and stored in this manner is utilized in editing knowledge data, and in this embodiment, is utilized for inputting rule parameter data.

FIG. 3 shows the input operation of rule parameters in this embodiment.

When a user (in this case, is often a person who maintains and adjusts the system) starts inputting rule parameters using the input terminal 18, the user first selects a rule template (200). That is, by repeating the operation of inputting rule template data as described above, a plurality of pieces of rule template data are stored in the rule template database 22. In step 200, for example, a menu of rule templates is displayed on the screen of the input terminal 18, and the user selects one of the rule templates.

Next, the parameter input section 24 reads out the rule name section 100 from the rule template data related to the selected rule template (202). The read contents of the rule name section 100 are displayed on the screen of the input terminal 18 (204).

FIG. 4 shows an example of an input screen in this embodiment.

As shown in this figure, the contents of the rule name section 100 read out in step 202 are displayed in the top column 300 of the input screen.

Next, the parameter input section 24 reads out the Japanese expression section 102 of the rule template data from the rule template database 22 (206).

The read Japanese expression part is displayed on the screen of the input terminal 18 (208). In this embodiment, the Japanese expression of the rule template, which is the content of the Japanese expression section 102, is displayed in a column 302 below the column 300 in which the rule name is displayed.

Next, the parameter input unit 24 counts the number M of rule parameters in the rule template data (210). That is, the number M of rule parameters surrounded by ) in the Japanese expression section 102 is determined.

After that, the parameter input section 24 skips the rule template section 104 (212), and the parameter definition section 106.
(214). Thereby, the parameter input unit 24 obtains information regarding the attributes of the rule parameters.

Next, the parameter input unit 24 reads input rule parameter data related to the rule template from the rule parameter database 26 (216).

The parameter input unit 24 further displays the rule parameters in a table format on the screen of the input terminal] 8 (218
).

In this embodiment, the number M of rule parameters is determined in step 210, and the parameter input unit 24 displays the rule parameter items on the screen of the input terminal 18 in accordance with this result. For example, in FIG. 4, in addition to items related to the number of rule parameter sets, items for rule parameters <A> and <B> are displayed. Generally, the number of items is determined according to the number M of rule parameters.

Furthermore, below the display of these items, a parameter input section 24 is provided.
The rule parameter data read from the rule parameter database 26 is displayed. That is, the rule parameter data is displayed in a table format corresponding to the displayed items. For example, if there are 15 sets of rule parameter data, each set of data is displayed in order from the top. The number of sets that can be displayed on one screen is physically determined by the screen size of the input terminal 18.

Next, function selection is performed using the function menu (220). That is, the parameter input unit 24 displays a function menu related to function selection on the screen of the input terminal 18. In FIG. 4, this function menu is displayed in the bottom column 304 of the input screen. The displayed function menu is, for example, “
In other words, the parameter input section 24 has each function displayed as a function menu.The user can input the functions of the parameter input section 24 by selecting the function menu. Select a function.

When the user operates the input terminal 18 and selects a function menu, the function branch 222 is performed according to the selection result.
is executed. If the user selects a function menu other than "Exit", step 224 is executed;
Return to step 220 again. That is, when a function menu other than "End" is selected by operating the input terminal 18, the process corresponding to the selected function menu is executed, and the function menu selection waiting state continues.

The operation in step 224 is an operation corresponding to the selected function menu. For example, when the "Add" function menu is selected, the input operation for the next set of rule parameter data is executed following the already input rule parameter data. For example, when "Modify" is selected, the action to modify the rule parameters that have already been input is performed, and when "Delete" is executed, the action is to delete the rule parameters that have already been entered manually, or to the "Next page".
Or, if "previous page" is selected, the next page or previous page is displayed, respectively.

In addition, in these operations, if the attribute of the rule parameter data does not match the attribute read in step 214, a comment to that effect is displayed and a return to the original state (for example, return to the state before input) is performed. executed.

If it is determined in branch 222 that "end" is selected, step 226 is executed. In step 226, the rule parameter data is written to the rule parameter database 26. That is, when "end" is selected, the operation of adding or modifying rule parameter data ends. At this time, it can be considered that the necessary set of rule parameters for the rule template to be displayed has been input, so that the parameter input unit 24 writes the rule parameter data to the rule parameter database 26.

After the rule parameter data is written, a determination 228 is made as to whether or not to end the input processing. For example, when the user operates the input terminal 18 and inputs an instruction to end the input process, the input from the input terminal 18 is "
It is determined in decision 228 that the message indicates "end" and the process ends. Otherwise, step 200
and the operation is repeated.

In this way, the plurality of sets of rule parameter data written in the rule parameter database 26 are used to edit the knowledge data in the knowledge data editing section 28.

That is, the knowledge data editing unit 28 reads rule template data from the rule template database 22, reads rule parameter data corresponding to this rule template pig from the rule parameter database 26, and substitutes the latter for the former.
Create knowledge data.

This knowledge data has a structure as shown in FIG. 5, for example.

For example, rule template data related to a rule with the rule name "Prioritization is a rule" is imported from the rule template database 22 into the intelligence data editing section 28, and corresponding sets of rule parameter data are imported from the rule parameter database 26 into the knowledge data editing section. 28. In the knowledge data editing unit 28, the rule parameters imported from the rule parameter database 26 are substituted into the rule template related to the imported rule template data, and the number of pieces of knowledge data corresponding to each set of rule parameter data is edited. be done. For example, if there are three sets of rule parameters corresponding to "prioritization is a rule", three pieces of knowledge data are edited and created.

The knowledge data created in this way is stored in the knowledge database 14. Furthermore, as mentioned above, the inference unit 16
This will be used for inference in the future.

In the above explanation, a template related to "prioritization is a rule" was used as a rule template, but this may be related to another rule.

FIG. 6 shows an example of rule template data related to "equipment allocation rules," and FIG. 7 shows an input screen related to this rule template data.

Regarding such rules, it is also possible to input rule parameters, create knowledge data, etc. using similar means.

In this manner, according to the present embodiment, when inputting rule parameter data, the inputted rule parameters are displayed in a list in a table format on the screen of the input terminal 18. Therefore, operations such as confirming/verifying, additionally inputting, or modifying the input rule parameters can be easily and accurately performed.

In addition, since the contents of the rule template are displayed in Japanese, it is not necessary to be familiar with the grammar of production rules when inputting rule parameters, or to be proficient in the steps involved in inputting them. Even users who are not familiar or experienced can perform operations such as inputting accurately and easily.

[Effects of the Invention] As explained above, according to the present invention, the rule parameter data is displayed in a table format on the screen of the input terminal, so that it is easy to input, modify, confirm, and confirm the rule parameter data.
Verification-related operations become simple and accurate. Furthermore, the usability of the expert system can be improved because the user does not need to be familiar with the grammar of production rules or be skilled in inputting procedures.
