This paper describes the participation of the IRIT lab, university of Toulouse, France, to the Microblog Track of TREC 2012. Two different models are experimented by our team for the adhoc task: (i) a Bayesian network retrieval model for tweet search and (ii) a feature learning model for relevance classification. Experimental results show that Bayesian(More)
This paper describes the participation of the IRIT lab, University of Toulouse, France, to the Microblog Track of TREC 2013. Two different approaches are experimented by our team for the real-time ad-hoc search task: (i) a Bayesian network retrieval model for tweet search and (ii) a document and query expansion model for microblog search.
