Topic:	Query Answering over Expressive Fuzzy Ontologies Through Approximation
Abstract:	Fuzzy ontologies are envisioned to be useful in the Web. Efficient query answering over ontologies is one of the most useful services to support intelligent Web applications. On the one hand, ontologies serve as basic semantic infrastructure; on the other hand, being able to handle fuzzy and imprecise information is crucial to the Web. However, whether query answering in fuzzy OWL DL is decidable is still an open problem; there exist no reasoner even for entailment checking in fuzzy OWL DL. Approximation is believed to be a potential way to reducing the complexity of query answering over fuzzy OWL DL ontologies. In this paper, we propose two approaches to approximate fuzzy OWL DL ontologies with fuzzy DL-Lite ontologies. Preliminary evaluation suggests the indirect approach is more scalable.
