In this paper, we propose a novel method to propagate social annotation, which includes user-supplied tag data, to both queries and VSEs for semantically bridging them. Our proposed algorithm consists of three key steps: query annotation, vertical annotation and query intention identification. Our algorithm, referred to as TagQV, verifies that the social tagging can be propagated to represent Web objects such as queries and VSEs besides Web pages. Experiments on real Web search queries demonstrate the effectiveness of TagQV in query intention identification. 2009-04 Conference or Workshop Item PeerReviewed application/pdf http://www2009.eprints.org/185/1/p1209.pdf Liu, Ning <http://www2009.eprints.org/view/author/Liu=3ANing=3A=3A.html> and Yan, Jun <http://www2009.eprints.org/view/author/Yan=3AJun=3A=3A.html> and Fan, Weiguo <http://www2009.eprints.org/view/author/Fan=3AWeiguo=3A=3A.html> and Yang, Qiang <http://www2009.eprints.org/view/author/Yang=3AQiang=3A=3A.html> and Chen, Zheng <http://www2009.eprints.org/view/author/Chen=3AZheng=3A=3A.html> (2009) Identifying Vertical Search Intention of Query through Social Tagging Propagation.
