Abstract :
Formal Concept Analysis (FCA) has been widely applied in many fields recently. In this paper, we introduce how a domain ontology can be constructed based on FCA. The consequential ontology constructed in this way is graphically represented as a concept lattice. After constructing FCA-based ontologies, it is necessary to represent the FCAbased ontologies in a formalism for sharing and reasoning. Semantic Web Rule Language(SWRL), a W3C proposal, is an extension with Horn clause rules on OWL. We represent the FCA-based ontologies in SWRL with some extension, which can be more suitable for reasoning.
