一种基于内容过滤的科技文献推荐算法
A Content-Based Filtering Algorithm for Scientific Literature Recommendation
摘要
Abstract
Personalized recommendation techniques can help users to retrieval documents quickly and effectively from mass of electronic documents. However, existing content-based filtering algorithm don' t reflect that the users information demands change over time, it is difficult to distinguish the literature quality difference. According to these questions, time-based data weight and literature importance are proposed, in order to response user's interest as well as literature quality fit and unfit quality better. On this basis, a content-based filtering of scientific literature recommendation algorithm is presented in this paper. Experimental evaluations and theoretical analysis demonstrate that the proposed algorithm can improve the accuracy of recommendations.关键词
