中文摘要： 知识的个性化服务是解决信息过载的重要途径。为提供准确的知识服务，本研究把知识情境引入到知识的个性化服务中，以提升企事业单位重用组织记忆中知识的正确性和高效性，增强企事业单位的技术、竞争、商务和策略智能，为企事业的可持续发展提供强有力的知识保障。 为融合知识与知识情境，本研究以基于本体论的知识内容建模理论为基础，设计本体论表示语言，把知识和相关情境结合起来，从多层次和多角度对知识内容做概念化描述和开放性集成。 知识个性化服务的基础是用户的知识兴趣.本研究提供基于本体论的用户兴趣表示方法，并构造基于知识情境的用户兴趣挖掘方法，动态跟踪用户知识兴趣的演变。制定面向知识个性化服务的知识情境匹配策略、基于知识情境的知识过滤策略和面向知识实用化的知识个性化服务策略，为企业和政府部门的知识个性化应用提供理论和技术基础。

英文摘要： Knowledge personalized service is an important way to solve the information overload. To provide accurate knowledge services, this study introduces knowledge context to the knowledge personalized service to improve the accuracy and efficiency of reusing the knowledge in the organization memory of the enterprises, to enhance the technology, competition, business and strategy intelligence of enterprises, and to provide a strong knowledge guarantees for the sustainable development of enterprises. To integrate knowledge context into knowledge, based on the ontology-based knowledge modeling theory, this study designs ontology representation language to combine knowledge with knowledge context, and provides the knowledge content with conceptualized description and exoteric integration from multi-level and multi-angle. The foundation of knowledge personalized service is the user's knowledge interest. To dynamically adapt to the evolution of user knowledge interest, this study provides ontology-based user interest representation, and constructs the user interest mining method based on the knowledge context. By developing knowledge context matching strategy oriented to the knowledge personalized service, knowledge filtering strategies based on the knowledge context, and knowledge personalized service strategy oriented to
