The TREC 2006 Terabyte Track



Stefan Buttcher, Charles L. Clarke, Ian Soboroff


The primary goal of the Terabyte Track is to develop an evaluation methodology for terabyte-scale document collections. In addition, we are interested in efficiency and scalability issues, which can be studied more easily in the context of a larger collection. 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.
