Subject Re: Can we use TREC data set in open source?
Date Tue, 10 Sep 2013 05:10:59 GMT
I read here that there is a hosted
version of ClueWeb09 (the latest is ClueWeb12, for which I don't find a
hosted version), and to get access to it, someone from the ASF will need to
sign an Organizational Agreement with them as well as each individual in
the project will need to sign an Individual Agreement (retained by the
ASF). Perhaps this can be available only to committers.

Though, we need to get access to ClueWeb12 if we want to publish Lucene
results on the latest data set. TREC papers are already based on that

But if we just want to measure performance, relevancy etc., ClueWeb09 could
be a good start.
