| 摘 要： | 针对知识密集型企业知识利用中存在的问题,提出了基于本体的主动式知识系统OPKS,以促进知识的利用.OPKS以主动式知识服务为基本思想,以用户知识需求为驱动因素,通过用户知识需求模型描述用户知识需求的决定因素.利用本体描述异构知识源语义,利用本体映射实现异构知识源互操作.通过用户知识需求与知识源匹配找到所需的知识,主动提供给用户.采用UML对OPKS进行系统分析和设计,采用Java语言进行实现.某研究所应用表明OPKS能提高知识密集型企业知识利用效率.

| Abstract: | With the aim to address the problems presented in knowledge utilization in knowledge-intensive enterprises,the ontology-based proactive knowledge system(OPKS) is put forward to improve knowledge utilization.Proactive knowledge service is taken as the basic idea in the OPKS.The user knowledge requirement is taken as the driving factor and described by the user knowledge requirement.Ontologies are used to present the semantic of heterogeneous knowledge sources and ontology mapping is used to realize the interoperation of heterogeneous knowledge sources.The required knowledge is found by matching the user knowledge requirement with knowledge sources and is provided to the user proactively.System analysis and design of OPKS is carried on by adopting UML.The OPKS is implemented in Java language.Application in a certain institute shows that the OPKS can raise efficiency of knowledge utilization in knowledge-intensive enterprises. |
