摘要

In this paper, we describe fuzzy CARIN, a knowledge representation language combining fuzzy Description Logics with Horn rules. Fuzzy CARIN integrates the management of fuzzy logic into the non-recursive CARIN language. We introduce the decision problems of answering to conjunctive queries, unions of conjunctive queries and the existential entailment problem and provide a sound and complete algorithm that permits reasoning with the DL fuzzy extended with non-recursive Horn rules. This extension is most useful in realistic applications that handle uncertain or imprecise data such as multimedia processing and medical applications.
