Overview of the TREC 2004 Terabyte Track

Charles L. A. Clarke, Nick Craswell, Ian Soboroff
2004 Text Retrieval Conference  
The Terabyte Track explores how adhoc retrieval and evaluation techniques can scale to terabyte-sized collections.  ...  For TREC 2004, our first year, 50 new adhoc topics were created and evaluated over a a 426GB collection of 25 million documents taken from the .gov Web domain.  ...  The proposal for a TREC Terabyte Track was initiated at a SIGIR workshop in 2003 and accepted by the TREC program committee for TREC 2004.  ...
