Abstract

Fuzzy Description Logics (f-DLs) have been proposed as formalisms capable of capturing and reasoning about imprecise and vague knowledge. The last years, research in Description Logics, and also in f- DLs, is largely focused on the development of languages where complexity of query answering is as efficient as query answering in data bases. One such example is the DL-Lite language and its fuzzy extension f-DL-Lite. In the current paper we present various a variety of query languages by which we can query a fuzzy DL-Lite knowledge base. Then, we present a prototype implementation for querying f-DL-Lite ontologies.
