Formal concept analysis based ontology merging method

With the growing usage of ontologies, different ontologies are constructed in the same domain from different specialist´s knowledge structures, this results in ontology heterogeneity, and the interoperability of ontologies is seriously blocked by ontology heterogeneity. It is known that Ontology Merging is an effective approach to solve this problem, so a novel method FCA-OntMerge for ontology merging is proposed in this paper. Firstly, ontologies are converted to formal context (the storage format of Concept Lattice). Secondly, the strict and perfect mathematical principle of concept lattice is obeyed to merge. Finally, a new ontology is generated. In terms of general performance, the experimental verification result reveals that the proposed method works well in solving the problem of ontology heterogeneity.
