Session Track Overview∗

University of Essex at the TREC 2010 Session Track

This paper provides an overview of the experiments we carried out at the TREC 2010 Session Track. We propose an approach for interpreting reformulated queries by using query expansions derived from anchor logs which we envisage to be a potential alternative to query logs. We show that expansion with terms or phrases extracted from anchor logs improves the retrieval performance over a search ses...

Overview of the TREC 2011 Session Track

This overview is organized as follows: in Section 2 we describe the tasks participants were to perform. In Section 3 we describe the corpus, topics, and sessions that comprise the test collection. Section 4 gives some information about submitted runs. In Section 5 we describe relevance judging and evaluation measures, and Sections 6 and 7 present evaluation results and analysis. We conclude in ...

Overview of the TREC 2013 Session Track

The TREC Session track ran for the fourth time in 2013. The track has the primary goal of providing test collections and evaluation measures for studying information retrieval over user sessions rather than one-time queries. These test collections are meant to be portable, reusable, statistically powerful, and open to anyone that wishes to work on the problem of retrieval over sessions. The exp...

Autoadapt at the Session track in TREC 2010

This paper provides an overview of the experiments we carried out at the TREC 2010 Session Track. We propose an approach for interpreting reformulated queries by using query expansions derived from simulated query logs. We show that this approach can improve the retrieval performance over a baseline system.

BUPT_WILDCAT at TREC 2011 Session Track

This paper is an overview of the runs carried out at TREC 2011 Session track, which proposes several approaches to improve the retrieval performance over one session including the search model based on user behavior, VSM_meta similarity model, optimization based on history ranked lists, optimization based on user‟s attention time and anchor log. The evaluation results show that our implementati...
