PKUICST at TREC 2012 Microblog Track

Abstract

This paper describes the PKUICST's entry into the TREC 2012 Microblog track. In this year of microblog track, we participate in both the Real-time Adhoc Task and Real-time Filtering Task. In the Real-time Adhoc Task, we designed and conducted a series of experiments based on different retrieval models, namely Real-time Tweet Ranking (RTR) model and learning to rank framework. In the Real-time Filtering Task, we adopted various strategies to determine the filtering threshold. Official results demonstrate that our approach obtains convincing performances and more unofficial runs lead to some further conclusions.
