Their tagged frequency indicates the user attentions with various degrees. This makes annotations a good resource for summarizing multiple topics in a Web page. In this paper, we present a tag-oriented Web document summarization approach by using both document content and the tags annotated on that document. To improve summarization performance, a new tag ranking algorithm named EigenTag is proposed in this paper to reduce noise in tags. Meanwhile, association mining technique is employed to expand tag set to tackle the sparsity problem. Experimental results show our tag-oriented summarization has a significant improvement over those not using tags. date: 2009-04 pagerange: 1195-1195 event_title: 18th International World Wide Web Conference event_location: Madrid, Spain event_dates: April 20th-24th, 2009 event_type: conference refereed: TRUE citation: Zhu, Junyan and Wang, Can and He, Xiaofei and Bu, Jiajun and Chen, Chun and Shang, Shujie and Qu, Mingcheng and Lu, Gang (2009) Tag-Oriented Document Summarization.
