On The Validation of Fuzzy Knowledge Bases

摘要: Roughly speaking, a knowledge base is “potentially inconsistent” or incoherent if there exists piece of input data which respects integrity constraints and leads to inconsistency when added the base. In paper we use framework possibility theory in order discuss this problem for fuzzy bases. More particularly consider case where such bases are made parallel rules. There exist several kinds rules: certainty rules, gradual For each kind, “potential consistency” appears be different. Only rules pose serious coherence problems. caracterize what conditions have satisfy avoid with facts. The expression constraint terms impossibility qualification discussed. redundancy, also interest validation, briefly addressed
