Deriving synonymies and homonymies of object classes in semi-structured information sources

The problem of handling both the integration and the cooperation of a large number of semi-structured information sources is today a challenging issue. In this context, a central role can be played by the knowledge about the semantic relationships between object classes belonging to di erent semi-structured information sources (inter-source properties). In this paper we propose a semi-automatic approach for extracting two kinds of inter-source properties, namely synonymies and homonymies, from di erent semi-structured information sources. In order to carry out the extraction task, we introduce both a conceptual model for representing object classes belonging to semi-structured information sources and a metrics for measuring the strength of the semantic relationships between object classes belonging to the same semi-structured information source.
