Abstract:By introducing the concepts of valuation density function and edge density function, a definition of probability truth degree for formula in the continuous value propositional logic L^* is proposed, some inference rules of probability truth degree are studied.On this groundwork, three similarities are given which discusses the properties of the relationship.By introducing similarity degree, the definition of pseudo-distance is proposed.And the structure and properties of logical metric space are discussed in details.Thus the basis for the inference degree's numerical is proved.
Keywords:valuation density  probability truth degree  inference rule  similarity degree  pseudo-distance
