Abstract
The paper reveals the basic principles of building expert systems in the aviation industry. A model of knowledge representation that provides information and structural reliability of the expert system's knowledge base for describing aircraft structures has been developed. The article analyzes the paradigmatic features of aerospace terminology in order to improve the efficiency of information search. A method for resolving lexical ambiguity of a search query in the knowledge base is proposed. Inference engine and explanation mechanism of the knowledge base premised on the Charles Fillmore's case grammar is described. The grammatical cases make it possible to determine the semantic and syntactic structure of the output sentence. Restrictions show the number of participants in the situation that a verb can attach, it is possible to provide effective output of information from the knowledge base.
