- Abstract:
- How to use the social tagging information to improve the effect of query expansion is a current re-search hotspot in the information retrieval field, In this paper, according to the data characteristics of socialtagging systems, we propose a modified social similarity algorithm called “ Weighted SimRank”( WSR ),which is used to improve the effect of query expansion. When the edge weighted values between labels andweb pages are caleulated, the WSR algorithm takes into account the number of co-occurrence users with tagsand web pages as well as the number of different web pages labeled by every same tag. All the experiments arecarried out on a real-world annotation data set which is sampled from the website del. icio. us. The experimen-tal results show that our proposed WSR method can effectively measure the similarity of annotations. Comparedto the other social-annotation-based methods, WSR produces more useful query expansion information and a-chieves better performance.
