BJUT at TREC 2014 Microblog Track

Abstract

This paper describes the second participation of BJUT in the TREC Micro-blog Track. Two tasks are proposed in this year, including ad hoc search task and tweet timeline generation task. We attended the first task and focused on the method for re-ranking of the returned search results. Specifically a graph-based method is proposed to re-rank the twitters returned by the official API, namely we re-rank the results by detecting whether some given characteristics are existing or not. Also, we introduce the details of our system, which consists of data preprocessing, system structure, and rank method & results analysis module.
