Research on Tree Segmentation-based Ontology Mapping

Abstract

Ontology mapping is a core task to achieve interoperability among the distributed and heterogeneous ontologies. The quality of ontology mapping is still not good due to the inconsideration of semantic information of the ontology. This paper proposes an ontology mapping method based on tree segmentation. It first divides the ontology into a set of sub-trees with different granularities according to the structure of the ontologies, then use Sub-tree Mapping Algorithm to map them. Preliminary experiments demonstrate that the proposed mapping method performs well in both precision and recall compared with the current mapping methods.
