Abstract:With the development of knowledge processing, the cognition and processing of negative knowledge receive widely attention. After extending the cognition about negation of fuzzy judgment sentences, one form of fuzzy judgment sentence with contradictory, opposite and medium negation is proposed. And the corresponding semantic description and logic description are presented. On this basis, 3 kinds of fuzzy reasoning rules with different negations are obtained after extending the truth-valued range model, and an extended Compositional Rules of Inference (CRI) algorithm and a demonstration are presented.
