Abstract:

In TREC 2012, we participated in the search and filtering tasks of the Microblog Track. The Microblog track is in its second year, and whilst the real-time ad-hoc search task remained very similar to 2011, a new real-time filtering task was introduced. For both tasks, we made use of temporal evidence and a burst detection algorithm to re-rank documents created during bursty periods. We also made extensive use of query expansion, which yielded good results in the ad-hoc task, but mixed results in the filtering task. Many of our runs were well above the TREC Median, and the methods we propose show promise for application to Twitter.
