模糊检索系统研究

模糊性是人类思维和客观事物普遍具有的属性之一。为了克服现行计算机信息系统的局限性 ,模糊检索应运而生。运用模糊技术开发的计算机信息系统既允许用户用自然语言进行信息查询 ,又能给出输出信号项与用户查询的关联度 ,协助用户完成信息处理任务 ,因而具有一定的人脑进行模糊信息处理的能力。简要讨论了模糊检索系统的结构 ,模糊知识库及其管理 ,模糊数据库的组织等。

Research on Fuzzy Retrieving System

Fuzziness is one of the general characteristics of human thinking and objective things. In order to overcome disadvantages of the present computer information systems, fuzzy searches emerge as the times require. The computer information systems, developed by fuzzy techniques, can both allow queries in natural language and provide relational degrees of all output information items to users' requirement, and thus be possessed of the ability of human brain for fuzzy information processing. This paper discusses the architechiture of fuzzy retrieving systems, the organization of fuzzy databases, fuzzy knowledge bases and their management.;
