Abstract:

Semantic similarity search is one of the most promising methods for improving the performance of retrieval systems. We present an ontology-based semantic search method, called SemSim, which relies on the information content approach to evaluate the similarity among a user request and semantically annotated resources. The user request, as well as each annotated resource, is represented by a set of concepts of the reference ontology. On the bases of a comparative analysis, we show that SemSim outperforms the most representative methods proposed in the literature.
