IRIT at TREC 2012 Contextual Suggestion Track

In this paper we give an overview of the participation of the IRIT lab, University of Toulouse, France, in the TREC 2012 Contextual Suggestion Track. We present our personalized contextual retrieval framework, an approach for context processing, and two approaches for user preference processing. The ocial evaluations of our two submitted runs are reported and compared to the four baselines defined for the track. Evaluation results show that one of our submitted run was ranked 1 st among the 27 runs of the 14 participants for the two ocial evaluation measures of the track.
