摘要
中介逻辑是一种区分矛盾否定与对立否定、肯定一些对立知识间存在中介对象的逻辑系统。基于中介谓词逻辑描述模糊知识,合理修改与或图,将每一谓词表达式视为状态结点,把逻辑规则集合表示为状态搜索空间。在传统与或图搜索算法的基础上,修改启发函数,将模糊知识的推理问题转化为状态空间中的搜索问题,并给出了一种否定信息的处理方法。
Medium logic is a kind of logic system which differentiates contradiction from opposition,and affirms that there exists medium between some opposite information.Based on medium predicate Logic,the paper represents fuzzy knowledge,modifies and- or graph with reason,regards every predication expression as state node to convert logic formulary into searching space.Then the heuristic function of traditional searching method of and-or graph is modified in order to treat fuzzy reasoning problem as problem of searching for the most reliable goal node.It also gives a kind of treatment method to manage negative information.
