运动员训练专家系统知识库的设计与实现

Design and Implementation of Knowledge Base of Athlete Training Expert System

为了选拔和培养优秀的体育运动员在比赛中取得更好的成绩,构建了运动员训练专家系统知识库。此知识库将运动员选拔和训练等有关的知识和经验转换成计算机可处理的规则和事实,建立基于规则和事实的诊断树;该知识库采用判断树结构作为知识表示模式和推理方法,用自定义数据结构表示判断树的结点,该自定义数据结构既可表示答案结点又可表示判定结点,同时可以表示父结点和子结点之间的联系。该系统的推理过程简单来说是遍历判断树得到答案结点的过程,通过一系列的规则编码来实现,在遍历判断树时采用了谓词截断技术、数据管理技术,在Prolog控制Delphi界面时使用了Del GUI谓词技术,方便地实现了专家系统界面的动态生成。

In order to select and train excellent sports athletes to achieve better results in the competition,a knowledge baseof the athletes training expert system is built. The knowledge base about the knowledge and experience of athletes selection and train-ing into rules can be processed by computer and the fact that the establishment of rules and facts are based on the diagnosis tree. Theknowledge library uses decision tree structure as knowledge representation and reasoning method,and uses a custom data structurethat represents the tree node,the data structure can be customized said the answer node can represent decision nodes,at the sametime can be expressed between parent nodes and sub nodes contact. It is a tree traversal answer node of the inference process of thesystem is simple,achieved through a series of encoding rules,decision tree traversal in the predicate truncation technology,datamanagement technology,Prolog control in the Delphi interface using Del GUI predicate technique,to facilitate the realization of thedynamic interface generation expert system.
