U. Albany & USC at the TREC 2012 Session Track

چکیده
Research in Information Retrieval has noticed that it is often the case that in a search process, users begin an interaction with a sufficiently under-specified query and they will need to reformulate their query multiple times before they find desired information. In terms of this, researchers hypothesized that a search engine may be able to better serve a user “by ranking results that help “point the way” to what the user is really looking for, or by complementing results from previous queries in the sequence with new results, or in other currentlyunanticipated ways.” (Kanoulas, Carterettey, Hallz, Cloughx, & Sanderson, 2011). In 2012, the goal of session track is: (G1) to test whether system performance can be improved for a given query by using previous queries and user interactions with the system (including clicks on ranked results, dwell times, etc.), and (G2) to evaluate system performance over an entire query session instead of a single query. Our UAlbany and USC group joined the Session Track task by taking into account searcher behaviors during the course of their information seeking process. In the following, we give an overview of our approach, details of our submission runs, our results, and our conclusions about the results.

In this paper, we introduce our experiments carried out at TREC 2012 session track. Based on the work of our group in TREC 2011 session track, we propose several methods to improve the retrieval performance by considering the user behavior information over the session, which includes use query expansion based on meta data, query expansion based on click order, optimization based on history rank...

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 کاملOverview of the TREC 2010 Session Track
Research in Information Retrieval has traditionally focused on serving the best results for a single query. In practice however users often enter queries in sessions of reformulations. The Sessions Track at TREC 2010 implements an initial experiment to evaluate the effectiveness of retrieval systems over single query reformulations.

In this paper we give a brief overview of the Webis group’s participation in the TREC 2012 Session track. Our runs implement three main ideas: (1) distinguishing low risk sessions where we want to involve session knowledge in the form of a conservative query expansion strategy (only few expansion terms based on keywords from previous queries and seen/clicked documents/titles/snippets) from thos...
