New data release: Freebase annotations for TREC Million Query Track and Web Track queries

[Evgeniy Gabrilovich]

We have just released Freebase annotations of several commonly-used sets of queries, including TREC Million Query Track and Web Track queries. 

The annotation process was automatic (and hence imperfect :), and for every Freebase entity we recognized in a query with high confidence, we provided the beginning and end byte offsets of the entity mention, its Freebase identifier (mid), and the confidence level.

The annotated data is available at http://www.lemurproject.org/clueweb09.php/related-data.php, as well as at http://www.lemurproject.org/clueweb12.php/related-data.php (thanks to Jamie Callan and CMU for hosting this data!)

We hope this dataset will be particularly useful in conjunction with the forthcoming release of similarly annotated ClueWeb corpora (2009 and 2012 versions), which we hope will be available in a couple of months.

Evgeniy.
