Update on the TREC Entity track

The main development that I am pleased to report is the release of the final test topics. The test set comprises 20 topics, which is less than we originally aimed for, but this is what could be achieved within the time limits. We certainly wanted to avoid extending the deadlines even further.

Since the number of queries is probably too low to support generalizable conclusions, evaluation will primarily focus on per-topic analysis of the results, rather than on average measures.
It is also worth noting that many of the “primary” entity homepages may not be included in the Category B subset of the collection. In such cases the “descriptive” pages (including the entity’s Wikipedia page) are the best available.

The test topics can be downloaded from the TREC site (you need to be a registered participant for TREC 2009 to be able to access them).

The track’s guidelines have been updated and can be considered final, although minor changes or additions are possible, should anything need clarification.

The submission deadline is Sept 21, so there is still plenty of time. In fact, this might attract some more teams to participate, given that submissions for all other TREC tracks are due by the end of August, and many of these tracks use the same collection.
