摘要
从分析知识管理系统用户的浏览规律出发,以知识管理系统中的元数据为依托,创建了元数据Web页,提出了用户浏览区域和关联集的概念 在分析视图关键要素的基础上,通过对知识管理系统用户获取知识的过程进行分析,构造了用户浏览图和无环图,提出了基于关联集的无环图分解方法,并依据用户兴趣和知识内容构造了判断准则;根据此准则可生成一个充分反映用户意愿的知识管理系统视图 实际应用表明。
Users'interests are investigated through analyzing the regular pattern of their navigation in a Knowledge Management System, the concept of navigation-region and correlative-set are introduced to identify their needs and the corresponding metadata Web pages are built. Navigation map and no-loop map are constructed to record the processes of their acquiring knowledge. Navigation map is decomposed according to correlative-set, and then a judge rule including user interest and knowledge content is used to generate a user view. Experiments show that a user view combining with user interest can be acquired efficiently by this approach.
