Abstract

PURPOSE:To reduce a time for studying meaning of words by linking words related to knowledge utilized in reasoning and data base in which the explanation is stored in a knowledge base system, and outputting explanation of words of a uncertain meaning in explanation of outputted procedure of deduction utilizing the data base. CONSTITUTION:The system includes a word answering means 15 that receives request for explanation from an inputting means 14 on words in the explanation and conclusion indicated by an outputting means 13, taking out the explanation from a data base 19 and outputs to the outputting means 13. That is, the word answering means 15 takes out explanation of words stored in the data base 19 through a data base linking means 18, a knowledge base 17 and a knowledge base controlling means 16 and outputs to the outputting means 13. Accordingly, it is not necessary for user to know the meaning of words beforehand, and he can save trouble to study about words of uncertain meaning separately beforehand.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a response explanation method in a knowledge base system used in knowledge information processing.

〔overview〕

In a response explanation method in a knowledge base system used in knowledge information processing, the present invention outputs an explanation of words included in an inference result based on a knowledge base and an explanation of the inference process upon request. By providing a word response means that allows users to immediately recognize a word that they do not understand, this system is designed for the convenience of users.

[Conventional technology]

Conventionally, in knowledge-based systems, users have requested intermediate conclusions and conclusions obtained as a result of inferences made by inference means using knowledge stored in a knowledge base and data stored in a database. If there is a,
The explanatory means explained how the conclusion was arrived at.

[Problem that the invention seeks to solve]

By the way, in general, users of knowledge base systems often do not know the depth of the knowledge stored in the knowledge base, but when using the conventional knowledge base system described above, the explanation visually displayed by the explanation means ,
If there is a word that does not make sense, the user is burdened with searching for the meaning.

SUMMARY OF THE INVENTION An object of the present invention is to provide a response explanation method in a knowledge-based system that allows users to easily understand even if there are words that make no sense by eliminating the above-mentioned drawbacks.

[Means for solving problems]

The present invention provides a knowledge base for storing knowledge, a knowledge base management means for managing this knowledge base, an inference means for making inferences and drawing conclusions using the knowledge, and an input means for inputting requests into the knowledge base. , an explanation means for explaining the inference process of the above conclusion, an output means for visually displaying the above explanation and the above conclusion, a database for storing data, and a database linking means for linking the above database to the above knowledge base. In a knowledge base system that includes
The present invention is characterized by comprising word response means for receiving an explanation request from the input means for the words in the explanation and the conclusion displayed by the output means, and extracting the explanation from the database and outputting it to the output means. .

[Effect]

The present invention uses a word response means to respond to a user's request from a pre-stored database when there is a word that the user does not understand in the explanation and conclusion displayed on the output means. Take it out and display it on the output means.

Therefore, users do not need to know the meanings of words in advance (and can also save themselves the trouble of separately searching for words of unknown meaning).

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

In this embodiment, a knowledge base 17 that stores knowledge, a knowledge base management means 16 that manages this knowledge base 17,
An inference means 11 that uses the above knowledge to make inferences and draw a conclusion, an input means 14 that inputs a request into the knowledge base 17, an explanation means 12 that explains the inference process of the above conclusion, and a means 12 that makes the above explanation and the above conclusion visible. Output means 13 for displaying, database linking means 18 for linking the database 19 to the database 19 for storing data and the knowledge base 17
a word response that receives an explanation request from the input means 14 for the words in the explanation and the conclusion displayed by the output means 13 and extracts the explanation from the database 19 and outputs it to the output means 13; It includes means 15.

A feature of the present invention is that word response means 15 is provided in FIG.

Next, the operation of this embodiment will be explained with reference to the flowchart shown in FIG. First, the user inputs a request for inference execution to the input means 14 (step 1). Next, the inference means 11 uses the knowledge stored in the knowledge base 17 and the data in the database 19 linked by the database link means 18 via the knowledge base management means 16 to perform inference (step 2). . At that time, were you able to reach the conclusion of step 3? If no conclusion is reached, the process ends, but if a conclusion is reached, an explanation of the inference process in step 4 is required. By,
If not, is an explanation of the reasoning process in step 4 necessary? If it is not necessary, the explanation means 12 ends the knowledge base management means 1.
6, the word response means 15 outputs the explanation of the inference process to the output means 13.

(Step 5) In that case, do we need to explain the meaning of the word in Step 6 whose meaning is unknown? If it is not necessary, it is terminated, and if it is necessary, it is inputted by the input means 14 to request an explanation.
(Step 7). Next, the word response means 15 receives this request for explanation, retrieves the explanation of the word stored in the database 19 via the database link means 18, the knowledge base 17, and the knowledge base management means 16, and outputs it to the output means 13. (Step 8). and,
The operations from step 6 to step 8 are repeated until there are no more meaningless words.

〔Effect of the invention〕

As explained above, the present invention links a database storing words related to knowledge used in inference and their explanations to a knowledge base system, and stores explanations of meaningless words in the output explanation of the inference process in the database. By outputting using , it is possible to bridge the gap between the knowledge that the user has and the knowledge stored in the knowledge base, and the user can reduce the unnecessary time spent looking up the meaning of words. effective. Furthermore, it has the effect of making the knowledge base, which tends to become large, more specific.
