Abstract. 

The article presents the process of knowledge extraction and structuring in the medical subject area for the created expert system for diagnosing acute appendicitis. Knowledge was elicited from two experts. Difficulties in the formation of the feature space, which is necessary to determine the form of appendicitis, complications and differential diagnostics with other diseases similar in clinical picture, are noted. A key feature of the structured knowledge representation is, along with the attribute, characteristic and value of the feature, the inclusion of an “index sign” position, which indicates the stage of the pathological process or a possible diagnosis from the differential diagnostic range of acute appendicitis.

Keywords: 

expert knowledge, feature space, knowledge structuring, acute appendicitis, clinical diagnosis, ultrasound diagnosis of appendicitis, differential diagnosis.
