基于RSS技术的用户兴趣模型构建

The construction of user's interest model based on RSS technology

机构知识库是以资源共享为导向的学术交流渠道,具有很好的研究价值.本研究主要工作如下:①借助RRS的工作原理及技术,实现机构知识库中资源的有效整合;②引入本体概念以构建用户兴趣模型,用基于本体加权向量模型表示RSS源;③给出了显示和隐式两种信息收集的权值估计方式,据此构建了基于RSS的兴趣模型.

The institutional repository is an important academic exchange channel which considers the resource sharing as a guide. The present work is about the construction of the institutional repository and the main contribution is as follows. The resources integration of the institutional repository is effectively realized by using the RRS working principle and technology; the concept of ontology is introduced to con- struct the user＇s interest model by using the weighted vector model based on ontology expressed RSS source ; the RSS interest model is successfully constructed basing on the weight estimation of both the dis- play and two implicit kinds of information collection.
