In TREC 2013, we participated in the ad-hoc search task of the Microblog Track. The Microblog track, which is in its third consecutive year, has remained very similar to the last two. This paper describes the approaches we have implemented for Tweet retrieval, which comprehend query expansion, and baseline model selection. The results for all the runs submitted are well above the median achieved for all the automatic runs submitted to TREC. Furthermore, statistically significant improvements in terms of precision at 30, are reported for our automatic query expansion approach with respect to the baseline we chose. The methods here proposed show great potential for enhancing tweet retrieval performance and should therefore be further studied.
