CroMatcher - results for OAEI 2016

Ontology matching plays an important role in the integration of heterogeneous data sources that are described by ontologies. In order to find correspondences between entities of different ontolog ies, a matching system has to be built. CroMatcher is an ontology matching system that consists of several string and structural basic matchers. As individual basic matcher computes similarity between entities using information obtained from one or more co mponents of the entire ontology, all individual matching results need to be aggregated in order to achieve the better final matching results of compared ontologies. The CroMatcher system uses weighted aggregation method that automatically determines the we ighting factors of each basic matchers considering quality of its matching result. Also, the system uses iterative final alignment method that selects appropriate correspondences between entities of compared ontologies from the aggregated matching results. This is the third time CroMatcher has been involved in the OAEI campaign. The system is upgraded by introducing two new basic matchers that improved the matching results at this OAEI campaign. CroMatcher achieved excellent matching results for the three o ntology matching tracks in which it participated
