A KNOWLEDGE REPRESENTATION PERSPECTIVE - LOGICS FOR PARACONSISTENT REASONING

Paraconsistent logics are examined as an approach to knowledge representation devoted to the formalization of reasoning in the presence of contradictions. The adequacy of paraconsistent logics in such a perspective is described both on a general level and on a more specific level: discussion involves representative examples as well as special features (in the form of logical principles) of some significant paraconsistent logics. There is also a comparison of the paraconsistent logics approach with two alternative approaches, namely belief revision and non-monotonic logics. (C) 1994 John Wiley and Sons, Inc.
