最近,哈尔滨工业大学计算机系在知识库机研制方面取得新进展。该项目是国家科委863计划的研究课题。经过两年的研究和实验,研制出了一个可运行的实验模型系统(HITKBM 90)。 HITKBM 90以产生式系统作为知识表示及推理工具,以OPS语言的基本思想为基础,但与OPS语言有以下几点不同: 1.HITKBM 90以一台386微机作为前端机,用以组织和管理规则库及数据库。自行研制的一块硬件处理板用作知识库机的后端机,以加速Rete网的推理速度。前、后端机相互配合,完成知识库系统的管理。 2.HITKBM 90在前端机提供一套完整的规则库和数据库管理。OPS语言的规则和工作存贮元素(wme)只作为程序的一部分,没有独
Recently, Harbin Institute of Technology Department of Computer Science in the knowledge base machine made new progress. This project is a research topic of the 863 plan of the State Science and Technology Commission. After two years of research and experimentation, a working experimental model system (HITKBM 90) was developed. HITKBM 90 uses production systems as a knowledge representation and reasoning tool based on the basic idea of the OPS language, but differs from the OPS language in the following points: 1. The HITKBM 90 uses a 386 microcomputer as a front end to organize and manage Rule base and database. A self-developed hardware processing board is used as the backend of the knowledge base machine to speed up the reasoning of Rete network. Front and back-end machines cooperate with each other to complete the management of the knowledge base system. 2.HITKBM 90 in the front end machine provides a complete set of rules and database management. OPS language rules and work storage elements (wme) only as part of the program, there is no single
