In the paper the approach to automated construction of interpretation functions (axioms) of concepts and relations of the domain ontology during its training are considered. The method of recognizing the semantics of natural language texts and its representation in the form of descriptive logic.
In the paper a method an algorithm and tools for selection of knowledge from a text document are suggested. It is shown that this algorithm has to be multistage and involve hierarchical procedure of concepts recognition of relations, predicates and rules which are introduced into the resulting ontology.
In the paper the method of the automatic development of ontology has been developed. A method, algorithm and means for selection of knowledge from the text document is proposed. It is shown that this algorithm has to be multistage and involve hierarchical recognition procedure of concepts, relations, predicates and rules which are included into the resulting ontology.
