Abstract

This paper describes our entry into the TREC 2011 Microblog track. We submitted two runs in this year's track, both in real-time fashion and without any external resources. The runs were generated through a three-step procedure, including scoring, threshold selection and re-ranking. The evaluation results of our submitted runs significantly outperform the disjunctive baseline run. We conducted additional runs to show our score decay and threshold selection strategies to be exceptionally effective.
