Inconsistency Repair to Improve the Alignment Results of Ontology Matchers

Ontology inconsistency is one of the most important topics in the field of ontology matching. Until now many matchers are introduced but most of them suffer from inconsistencies. Many of the ontology matching tools have severe problems with respect to the quality of matching results and therefore the results of matching process is not adequate. In this paper, we focus on this topic and present a new method to produce better results from the matching process. The major novelty of this paper is in detecting the inconsistencies in ontologies before starting the matching process. In this phase, many problems caused by ontology diversity are resolved. Besides, some new patterns and inconsistencies in ontologies are detected and then refactoring operations are applied on them. At the end, one of the well-known matchers in OAEI is selected to evaluate our work. Experimental results show that the transformed ontologies are more efficient than original unrepaired ones with respect to the standard evaluation measures.
