基于本体的非结构化知识库系统研究

Research on Ontology Based Unstructured Knowledge Management System

本文提出一种基于本体的非结构化知识管理系统框架。在该框架中,知识库由知识体和应用本体两部分组成,可解决知识的重用和共享问题。知识检索可以通过知识地图导航和自动检索两种方式完成,有一定的智能性。知识管理门户采用XML和XSL相结合的开发方法,具有动态特点。本文还对知识库的安全管理方法进行了初步研究,提出了一个可用的知识库安全管理解决方案。

An ontology based unstructured knowledge management system framework is proposed in this paper. In this framework, knowledge base is composed of application ontology and knowledge objects, which can solve the problem of knowledge sharing and reuse. Knowledge retrieving can be achieved completed with knowledge map based navigation and automatic approach with a certain degree of intelligence. System portal are developed based on xrnl and xsl with a good dynamic characteristics. The security management method for knowledge base is studied and a useable solution is proposed.
