BFBEST知识库生成系统设计技术

本文介绍了医学专家系统开发工具BFBEST的知识库生成系统设计技术。包括:(1)灵活友好的用户接口,(2)帮助用户避免输入知识时的语法和语义错误;(3)允许用户用领域规范化形式的知识与系统对话,输入知识;(4)具有事务薄记功能;(5)具有对知识库进行增、删、改的能力;(6)能对输入知识进行完整性和一致性的检查;(7)能将知识的机内表示复原成规范化的形式;(8)具有传授式的部分自动获取知识的功能。 BFBEST开发机是在IBM-PC机上用Turbo-Prolog语言实现的。它实用性强、智能化程度高,能用来快速生成各种高性能的医学专家系统知识库。

Design Techniques of BFBEST Knowledge Base Generating System

This paper gives an account of the design technique of the knowledge-base generating system (i. e. developing engine) of BFBEST (Blackboard-Frame-Based Expert System Tool). The design technique includes the following: (1) to provide a well-engineered and smooth user interface,(2) to help the user avoid syntactic and semantic errors,(3) to allow the user to converse with the system in a language of knowledge of normal form, (4) to have important routine bookkeeping function, (5) to have the ability for revising the knowledge-base and debugging and augmenting knowledge function, (6) to be able to check the completeness and consistency of the knowledge, (7) to resume normal form from the internal form of knowledge,(8) to have the ability in automatic knowledge acquisition in teaching,etc.The BFBEST developing engine is implemented on IBM-PC computers with turbo-prolog language. It is heavily practical and highly intelligent,it may be used for rapid generation of knowledge-bases of various medical expert systems of high performence.
