METHODS OF FORMAL CONCEPT ANALYSIS IN INFORMATION SYSTEMS OF TECHNICAL SUPPORT
Applications of methods of formal concept analysis in the technology of classification of textual data being natural language text queries applied in information systems of technical support is considered. Original solution of text classification problem based on applying conceptual semantic models - conceptual graphs and conceptual lattices - is implemented. Application of conceptual graphs makes possible more precise acquiring concepts as word combinations from a text, including variants when words in a word combination are not adjacent.
