Automatically specifying parallel composition of matchers in ontology matching process

Ontology matching plays an important role in the integration of heterogeneous data sources. In order to find semantic correspondences between entities of different ontologies, various matchers can be used. When multiple matchers are integrated into a matching system, the issue of combining these matchers together and determining the importance of every basic matcher arises. In a parallel composition of basic matchers, several matchers are used independently, and then their results are aggregated. In this paper we propose a method for automatically determining weights of basic matchers in their parallel composition. An evaluation of the method is performed on case study examples concerning the matching of three ontology pairs, and a comparison with other aggregation methods is given.
