Tensor query expansion : a cognitively motivated relevance model
Symonds, Michael, Bruza, Peter D., Sitbon, Laurianne, & Turner, Ian (2011) Tensor query expansion : a cognitively motivated relevance model. In Proceeding of the 16th Australasian Document Computing Symposium, Australasian Document Computing Symposium, Canberra, ACT.
In information retrieval, a user's query is often not a complete representation of their real information need. The user's information need is a cognitive construction, however the use of cognitive models to perform query expansion have had little study.
In this paper, we present a cognitively motivated query expansion technique that uses semantic features for use in ad hoc retrieval. This model is evaluated against a state-of-the-art query expansion technique. The results show our approach provides significant improvements in retrieval effectiveness for the TREC data sets tested.
