The TREC 2006 Terabyte Track
Stefan Büttcher, Charles L. A. Clarke, Ian M. Soboroff · 2006
TREC 2006 is the third year for the track. The track was introduced as part of TREC 2004, with a single adhoc retrieval task. For TREC 2005, the track was expanded with two optional tasks: a named page finding task and an efficiency task. These three tasks were continued in 2006, with 20 groups submitting runs to the adhoc retrieval task, 11 groups submitting runs to the named page finding task, and 8 groups submitting runs to the efficiency task. This report provides an overview of each task, summarizes the results, and outlines directions for the future. Further background information on the development of the track can be found in the 2004 and 2005 track reports [4, 5].
