Straccia U. Answering vague queries in fuzzy DL-LITE. In: Proceedings of the 11th International Conference on Information Processing and Managment of Uncertainty in Knowledge-Based Systems, (IPMU-06) (Paris, July 04-07, 2006). Proceedings, pp. 2238 - 2245. E.D.K Paris, 2006.
Fuzzy Description Logics (fuzzy DLs) allow to describe structured knowledge with vague concepts. Unlike classical DLs, in fuzzy DLs an answer is a set of tuples ranked according to the degree they satisfy the query. In this paper, we consider fuzzy DL-Lite. We show how to compute efficiently the top-$k$ answers of a complex query (ie~conjunctive queries) over a huge set of instances.
