Overview of the TREC 2012 Web Track

Abstract : If you are an experienced participant, you may not need to read the full report. Apart from the results themselves (see tables 1, 2, and 3) little has changed from TREC 2011. A six-point scale was used for relevance assessment (see section 4.1). Limitations on available assessor time meant that some topics were judged to depth 30 and others to depth 20, as well as causing other minor problems (see section 4.3). However, our plans for next year, as outlined in the concluding section, are quite different from this year.
