摘要
本文提出一种基于关系的知识库模型．这个模型可根据用户提出的查询问题，对知识体进行有效的演绎查询，采用多层次多级别方法构造演绎检索过程，以达到减小搜索空间，减小知识冗余度，加快演绎推理速度的目的．
This paper proposes a model of knowledge query based on relation. According to query problems that users propose, this model can be used to proceed deductive query effectively for knowledge unit. The hierarchial method is used to construct deductive searching. This method is beneficial by decreasing search space and knowledge redundancy. Thus the speed of deductive reasoning can be raised.
