The TREC 2005 Terabyte Track



Charles L. Clarke, Falk Scholer, Ian Soboroff


The Terabyte Track explores how retrieval and evaluation techniques can scale to terabyte-sized collections, examining both efficiency and effectiveness issues. TREC 2005 is the second year for the track. The track was introduced as part of TREC 2004, with a single ad hoc retrieval task. That year, 17 groups submitted 70 runs in total. This year, the track consisted of three experimental tasks: an ad hoc retrieval task, an efficiency task and a named page finding task. Eighteen groups submitted runs to the ad hoc retrieval task, 13 groups submitted runs to the efficiency task, and 13 groups submitted runs to the named page finding task. This report provides an overview of each task, summarizes the results, and discusses directions for the future.
