Domain-Specific Query Augmentation using Folksonomy Tags: the Case of Contextual Advertising
Andrei Broder, Peter Ciccolo, Evgeniy Gabrilovich, Bo Pang · 2008
Folksonomies allow users to collaboratively tag a variety of tex-tual and multimedia objects with sets of labels. The largest folk-sonomy projects, such as FLICKR and DEL.ICIO.US, contain mil-lions of multi-labeled objects, and embed significant amounts of human knowledge. We propose a method for automatically using this knowledge to augment traditional IR systems, using contextual advertising as an application domain. Given a query, we first iden-tify a set of relevant tags, and then use tags that cooccur with them to augment the query. Importantly, our method performs domain-specific query disambiguation, and can actually learn that a query “menu ” is likely to have food connotation on FLICKR but user in-terface connotation on DEL.ICIO.US. 1.
