There is a knowledge acquisition/verification support device j described in Utility Model Application No. 1983-72562 (a) as a means of expressing rule-type knowledge representing the relationship between the rules and the knowledge in a single event/hypothesis matrix along with its confidence level.

〔実施例〕
次に、本発明の実施例について図面を参照して説明する
。The diagnostic knowledge organization method of the expert system of the present invention uses a plurality of event/hypothesis matrices, and the matrix name of the event/hypothesis matrix that is a child matrix is written in the hypothesis part of the event/hypothesis matrix that is a parent matrix. By describing the above-mentioned event/hypothesis matrices, the plurality of event/hypothesis matrices are layered, and the "events" that are symptoms that occur and the "hypotheses" that are considered to be the causes are In addition to showing the correlation between `` and ``, it is constructed by dividing and storing diagnostic knowledge classified by diagnostic level ranging from summary to detailed, by making the diagnostic level correspond to the hierarchy of the matrix. [Example] Next, an example of the present invention will be described with reference to the drawings.

There are ``digestive system'' matrix 4, ``respiratory system'' matrix 5, ``circulatory system'' matrix 6, and ``comprehensive diagnosis''.
It has a three-layer hierarchical structure from matrix 1 to these event/hypothesis matrices.

れの事象・仮説マトリックスごとに格納している。That is, the top-level "comprehensive diagnosis" matrix 1 prescribes rule-based knowledge to the extent that it is possible to roughly judge whether the disease is a surgical disease or a medical disease. In addition, "surgical diagnosis" matrix 2 and "internal medicine diagnosis" matrix 3 of the 2nd P1 layer
store rule-type knowledge regarding surgical diseases and rule-type knowledge regarding internal diseases, respectively. Further, in the third layer, rule-based knowledge regarding the fire extinguisher system, respiratory system, and circulatory system among internal medical diseases is stored for each event/hypothesis matrix.

In addition, knowledge at the same level is categorized by its diagnostic field.

、作業効率を向上させるという効果を有している。As explained above, the diagnostic knowledge organizing method of the expert system of the present invention realizes the level-by-level organization and modularization of collected diagnostic knowledge by providing a hierarchical structure to multiple event/hypothesis matrices. This has the effect of not only preventing a single event/hypothesis matrix from becoming too large, but also making it possible to organize knowledge in accordance with the hierarchical structure of the knowledge itself, improving work efficiency.

法。By using multiple event/hypothesis matrices and writing the matrix name of the event/hypothesis matrix that will be the child matrix in the hypothesis section of the event/hypothesis matrix that will be the parent matrix, you can create multiple event/hypothesis matrices. The matrix is stratified, and the multiple hierarchized event/hypothesis matrices show the correlation between the "event" that is a symptom that occurs and the "hypothesis" that is considered to be its cause, and also provides a summary to detailed information. A method for organizing diagnostic knowledge in an expert system, characterized in that diagnostic knowledge classified by diagnostic level leading to the above is divided and stored in a manner that corresponds the diagnostic level to the hierarchy of a matrix.
