摘要
本文研究了专家系统的知识表达和推理机制,提出了基于数据库的知识表达方式。这种方式使数据库具有了知识库的功能,使知识更容易表达和管理。同时,提出了满足这种表达方式的推理机制,提高了专家系统的推理效率。
In the paper, the knowledge description and reasoning mechanism is studied. Based on the research of the knowledge type, the Database-based knowledge representation is put forward. This method enables the database to have the knowledge base function, making knowledge representation and management handy. Meanwhile, to meet this representation, the reasoning mechanism based on database is brought out. And this mechanism improves the efficiency of Expert System.
