Summary

The ICTIR group's work on the TREC 2011 Microblog Track for tweets retrieval uses a basic query likelihood model with smoothing, considering author information and negative feedback. Queries are classified into three categories and refined feedback is constructed differently for each. Author topic models are trained for tweet expansion and smoothing, and a negative feedback model is trained to reduce noise impacts. Experimental results show that these methods improve retrieval performance greatly.
