| 摘 要： | 在分析一般产生式知识表示方式构造专家系统知识库存在的知识库膨胀、扩展困难、推理效率较低等问题的基础上,根据昆虫学专业特点和面向对象的思维方法,对专家系统知识库构造方法进行了尝试,提出了将专家系统知识库分离为结构数据、实例数据两个部分进行维护的思路。基于继承的专家系统知识库建造模式有效利用了生物进化的特征和面向对象的结构化继承特征,减小了数据体积,优化了数据分离维护、整体结合使用机制,提高了推理机工作效率,使专家知识库便于扩展及功能碾压。

| Abstract: | To use general generating expert system database will meet some problems such as expansion of database,difficulty of updating and low efficiency of logic rationalization.Our design which is based on entomology knowledge and thought of OO (Object Oriented) made some attempt about method of expert system database construction and brought forward a set of thoughts to maintain structure database and entity database separately.The method to build expert system database based on inherited way will save the space of necessary database,optimize detached maintenance of database and use them unitarily to show its function,improve the efficiency of reasoning machine.These features make it easy to perform and derive new functions from the framework of database. |
