Abstract

We combine the Semantic Web with the Web, as background knowledge, to provide a more balanced solution for Ontology Mapping. The Semantic Web can provide mappings that are missed by the Web, which can provide many more, but noisy, mappings. We present a combined technique that is based on variations of existing approaches. Our experimental results in two real-life thesauri are compared with previous work, and they reveal that a combined approach to Ontology Mapping can provide more balanced results in terms of precision, recall and confidence measure of mappings. We also discover that a reduced set of 3 appropriate Hearst patterns can eliminate noise in the list of discovered mappings, and thus techniques based exclusively in the Web can be improved. Finally, we also identify open questions derived from building a combined approach.
