Bobillo F., Straccia U. On qualified cardinality restrictions in fuzzy description logics under Lukasiewicz semantics. In: 12th International Conference of Information Processing and Management of Uncertainty in Knowledge-Based Systems. IPMU 2008 (Malaga (Spain), 22-27 June 2008). Proceedings, pp. 1008 - 1015. University of Malaga, 2008.
Fuzzy Description Logics have been proposed as a family of languages to describe vague or imprecise structured knowledge. This work deals with one of the less studied constructors, qualified cardinality restrictions, showing some counter-intuitive behaviours under Lukasiewicz semantics, and proposing a new semantics and the corresponding reasoning algorithm.
