Abstract

PURPOSE:To facilitate the input of rules and to improve the function of a knowledge acquisition processor by transforming the 1F-THEN... type rules into a matrix table. CONSTITUTION:A knowledge input processing means 31 supplies the contents (conditions, conclusion, reliability to the conclusion) of each item contained in a matrix table data by an interactive way or a collective processing way and stores them in a matrix data file 32. A matrix/rule conversion means 33 converts the data stored in the file 32 into the rules consisting of programs of the 1F-THEN... type and stores them in a knowledge base 2. This converted base 2 undergoes the correction, editing of the knowledge through a conventional knowledge acquisition processing means 1. While the rules stored in the base 2 and corrected by the means 1 are stored in the file 32 in the form of the new or updated matrix table data via the adverse conversion processing carried by the means 33.

Description

Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a knowledge acquisition processing device, and in particular [F~T HE
The present invention relates to a knowledge acquisition processing device that collectively stores N... type rule-based knowledge (hereinafter simply referred to as rules) in a knowledge base.

[Conventional technology]

Conventionally, in this type of knowledge acquisition processing device, the MMi of rules to the knowledge base is IF~THEN for each rule.
- This was done either by creating a type program or by interactively inputting data into the ~ part (conditional part) and the ... part (conclusion part).

[Problem that the invention seeks to solve]

In the conventional knowledge acquisition processing device described above, rules are stored in the knowledge base either by creating an IF~THEN... type program for each rule, or by creating ~ part (condition part) and...
・Conversational data entry into the conclusion section (conclusion section) required a program to be created even for a small number of rules, and interactive data entry was required when inputting a large number of rules. However, the disadvantage is that it takes a lot of time.

Furthermore, in the case of program creation or interactive data input, it is inconvenient to check the validity and duplication of each rule, and there is also a drawback that it is difficult to list all rules.

In view of the above points, an object of the present invention is to provide a knowledge acquisition processing device that allows rules to be easily input in a matrix table format.

Means for Solving Problem C] The knowledge acquisition processing device of the present invention is a knowledge acquisition processing device capable of inputting rule-type knowledge, accumulating it in a knowledge base, and modifying the accumulated rule-type knowledge. knowledge input processing means for inputting type knowledge as matrix table data in a matrix table format; a matrix table data file for accumulating the matrix table data input from the knowledge input processing means; and a matrix/rule conversion processing means for reading data, converting it into the rule-type knowledge, and storing it in the knowledge base.

[Effect]

In the knowledge acquisition processing device of the present invention, the knowledge input processing means inputs rule-type knowledge as matrix table data in a matrix table format, stores the input matrix table data in a matrix table data file, and outputs the matrix table data to the matrix/rule conversion processing means. reads the matrix table data from the matrix table data file, converts it into rule-based knowledge, and stores it in the knowledge base.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. i acquisition processing device is conventional knowledge
a1) In addition to the acquisition processing means 1 and the knowledge base 2, the knowledge input processing means 3L matrix table data file 3
2 and matrix/rule conversion processing means 33.

The knowledge input processing means 31 uses an IP as illustrated in FIG.
-THEN...The contents of the ~ part (conditional part) of the type rule,
・・・Contents of the part (conclusion part) and reliability of the conclusion part (Cz
, +, etc.) in a two-dimensional matrix table format in an interactive or batch processing manner.

Note that the matrix table illustrated in FIG. 2 has a format in which multiple conditions can be set for the same conclusion, so that complex conditions for the conclusion can be expressed. Also,
Positive and negative conditions can be set for the conclusion. Furthermore, if the conclusion is positive, write the confidence level in the 10 column, and if the conclusion is negative, write the confidence level in the - column. It has a format that can be expressed at the same time.

The matrix table data file 32 is a file that stores matrix table data input from the knowledge input processing means 31.

The matrix/rule conversion processing means 33 is a means for reading matrix table data stored in the matrix table data file 32 and converting it into an IF-THEN . . . type rule format program.

Next, the operation of the knowledge acquisition processing device of this embodiment configured as described above will be explained.

When storing IF-THEN... type rules in the knowledge base 2, the knowledge input processing means 31 stores the contents of each item (conditions, conclusion, reliability value for the conclusion) in the matrix table data illustrated in FIG. ) is input interactively or in batch processing, and the input matrix table data is temporarily stored in the matrix table data file 32.

Next, the matrix/rule conversion processing means 33 reads the matrix table data accumulated in the matrix table data file 32, converts the read matrix table data into rules formed by an IF-THEN type program, and converts The rules are supplied to the knowledge base 2 and Mm is executed.

The rules stored in the knowledge base 2 by the matrix/rule conversion processing means 33 can be modified, edited, etc. by the conventional knowledge acquisition processing means 1.

Furthermore, the rules in the knowledge base 2 that have been modified or edited by the conventional knowledge acquisition processing means 1 are transformed into
F-THEN... type rules are reversely converted to matrix table data, and matrix table data file 3 is created.
2 can be multiplied as new or updated matrix table data.

〔Effect of the invention〕

As described above, according to the present invention, rules can be easily input interactively or in a batch process by using a knowledge input processing means capable of inputting matrix table data when inputting rule-type knowledge into a knowledge base. effective.

Furthermore, by using a matrix table as an expression format when inputting rules, it is possible to easily list the knowledge and to input the knowledge in an organized manner.

Furthermore, by converting the rules in the accumulated knowledge base back into matrix table format data, you can reconfirm input knowledge, discover contradictions between rules, systematically organize knowledge, etc., and acquire knowledge. This has the effect of significantly improving the functionality of the processing device as a whole.

Furthermore, depending on the settings of data items in the matrix table, IF-THEN... type rules can be expressed flexibly.
