THE DOMAIN ONTOLOGY BUILDING BASED ON SEMANTIC DESCRIPTION OF COMPREHENSIVE EVALUATION

The readily available comprehensive evaluation index system is analyzed to indicate its semantic concepts, and the document of index system is also pretreated. The concepts of indicators and the relationships among the indicators are all extracted. Based on these concepts and relationships, a basic ontology is constructed. Then a concept lattice on the basis ontology is obtained, and its concept description is further enriched. Finally, this concept lattice is converted into the domain ontology by using the methods and tools of formal concept analysis.
