چکیده
This paper details Cengage Leaning’s TREC 2010 Session track submission and our efforts to improve retrieval performance over a user’s session. We use a number of different techniques to achieve this goal including query term weighting, query expansion and re-ranking. In this paper we detail these techniques and the results of our submission. Using our query term weighting technique combined with our corpus term collocation query expansion we were able to achieve 0.2375 for the [email protected] metric.

Cengage Learning at TREC 2011 Medical Track
This paper details Cengage Learning’s submissions for this year’s TREC medical track. The techniques we used fall roughly into two categories: information extraction and query expansion. From both the queries and the medical reports, we extracted limiting attributes, such as age, race, and gender, and labeled terms appearing in the Unified Medical Language System (UMLS). We also used three diff...

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...

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.

At Rutgers, we approached the Session Track task as an issue of personalization, based on both the behaviors exhibited by the searcher during the course of an information seeking episode, and a classification of the task that led the person to engage in information-seeking behavior. Our general approach is described in detail at the Web site of our project (http://comminfo.rutgers.edu/imls/pood...
متن کاملThe Role of Anchor Text in ClueWeb09 Retrieval
This report describes the work done at The University of Melbourne with the ClueWeb09 data corpus for the Web Track of TREC-2009 and TREC-2010, and for the Session Track of TREC-2010. We found that the impact-based retrieval model works well for the corpus, and that, along with some other factors, the use of an anchor text collection significantly boosts the retrieval effectiveness.
