Terrier/WT2G

WT2G

WT2G is a general Web crawl, used by the TREC 1999 Web track. It can be obtained from the [WWW] University of Glasgow. The topics and qrels are available from the [WWW] TREC website.

Indexing the WT2G collection is easy with Terrier. No terrier.properties are required to be altered from the default created by trec_setup. If you wish URLs in your index, then set the following properties:

trec.collection.class=TRECWebCollection
indexer.meta.forward.keys=docno,url
indexer.meta.forward.keylens=26,256

See the Terrier documentation on [WWW] Web-based Terrier to see how to build a Web search engine for this collection.
