摘要
这里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效率。
In the paper, the knowledge description and the reasoning mechanism is studied. Based on the research of the knowledge type, the Database- based knowledge representation is put forward. This method makes the database have the knowledge base function, makes the knowledge representation and the knowledge management easy. At one time, to meet this representation, the reasoning mechanism based on database is brought out. And this mechanism improves the efficiency of Expert System.
