摘要:

协同标签在信息系统的组织中发挥着越来越重要的作用。在本文中,我们研究了个性化推荐模型,利用用户,对象和标签之间的三元关系。我们提出了一种基于用户偏好和标签信息的用户相似性度量方法。两种类型的用户之间的相似性计算,通过使用一个基于扩散的过程,然后集成推荐。我们测试了所提出的方法在一个标准的协同过滤框架与三个指标:排名分数,召回率和精度,并证明它比常用的余弦相似性表现得更好。

英文摘要:

Collaborative tags are playing more and more important role for the organization of information systems. In this paper, we study a personalized recommendation model making use of the ternary relations among users, objects and tags. We propose a measure of user similarity based on his preference and tagging information. Two kinds of similarities between users are calculated by using a diffusion-based process, which are then integrated for recommendation. We test the proposed method in a standard collaborative filtering framework with three metrics: ranking score, Recall and Precision, and demonstrate that it performs better than the commonly used cosine similarity.
