Pan, Jeff Z., Stamou, Giorgos, Stoilos, Giorgos, Taylor, Stuart and Thomas, Edward (2008): Scalable querying services over fuzzy ontologies. In: Proceedings of the 2008 International Conference on the World Wide Web 2008. pp. 575-584. Available online

Fuzzy ontologies are envisioned to be useful in the Semantic Web. Existing fuzzy ontology reasoners are not scalable enough to handle the scale of data that the Web provides. In this paper, we propose a framework of fuzzy query languages for fuzzy ontologies, and present query answering algorithms for these query languages over fuzzy DL-Lite ontologies. Moreover, this paper reports on implementation of our approach in the fuzzy DL-Lite query engine in the ONTOSEARCH2 system and preliminary, but encouraging, benchmarking results. To the best of our knowledge, this is the first ever scalable query engine for fuzzy ontologies.

Pan, Jeff Z. and Horrocks, Ian (2006): OWL FA: a metamodeling extension of OWL D. In: Proceedings of the 2006 International Conference on the World Wide Web 2006. pp. 1065-1066. Available online

This paper proposes OWL FA, a decidable extension of OWL DL with the metamodeling architecture of RDFS(FA). It shows that the knowledge base satisfiability problem of OWL FA can be reduced to that of OWL DL, and compares the FA semantics with the recently proposed contextual semantics and Hilog semantics for OWL.
