Using Formal Concept Analysis for Ontology Building
Jin Yuan-ping · Microcomputer Development · 2005
With the extending of the scope of information sharing and data exchange, semantic data integration is becoming the hot spot in the research of database technology. Ontology, by way of formal specification of share concepts, provides a method to resolve the semantic heterogeneous, since it can be used to express the semantics of data sources, identify and construct the semantic relationship of the concepts, compass the sematic consistency.Traditional relational databases is still the main means to store data for its characteristic of mature technique, widely used applications, powerful data management and security. However, relational data only express the attribute/value relation, it doesn't have the semantic describing ability. Therefore, it is an important research orientation that how to take out the semantics in the relational data directly, refine the rich semantic information, construct the ontology, make up the defect of relational data schema.This paper discusses the technique of using formal concept analysis in combination with data model and the data information for ontology construction. On the basis of analyzing present status about building ontology,introduces the formal concept analysis method concerned. Finally, under given data model and data information,demonstrates how to construct an ontology.
