【摘要】 分析了目前企业知识应用存在的问题,提出了基于知识需求的主动式知识系统.描述了系统的框架结构,分析了系统的组成.研究了知识需求的描述及生成、进化算法,提出了异构知识源查询处理方法,分析了多On-tology管理中的问题:Ontology映射和进化等.目前,其原型系统已在某航空研究所得到初步应用,有效促进了异构知识的应用.更多还原

【Abstract】 The proplems which appear in an enterprise knowledge application at present are analysed.Active knowledge system based on knowledge requirement is proposed aimming to solve the problems.The system architecture is described;and the constitution of the system is specified.Knowledge requirement description,algorithms of knowledge requirement generation and evolution are studied.Query process method of heterogeneous knowledge sources is brought forward and problems in multiple ontologies management,such as ontology mapping,ontology evolution,are analysed.At present,the prototype of the system has been applied to a certain aeronautical institute and efficiently improved application of heterogeneous knowledge.更多还原
