NODE-MATCH TOOL User Guide

Simple ontology matching algorithms are based on lexical measures that only consider text similarity. Taking the shape and structure of the ontology into account while matching can lead to better results [1, 2, 3]. Node-Match illustrates the difference between the two approaches. It is based on S-Match [4] an open source toolkit for lightweight ontology matching and alignment. S-Match supports a rich GUI for designing lightweight ontologies and several ontology alignment algorithms. We use the Department Ontology from the running example in [1] to show the difference between difference ontology matching algorithms. The following screenshot shows the two ontologies loaded in the GUI of S-Match. The ontologies represent information about different departments at a university
