Participants are provided with a set of 50 queries, together with the Freebase ID for each entity in these queries.? Queries can now be found under the Active Participants portal at TREC (http://trec.nist.gov/act_part/act_part.html).
We will be using the Clueweb12 document collection. Participants can also use Clueweb12 Category B. However, all the runs will be evaluated using the same evaluation setup.
