Building Strategies, a Year Later

Wouter Alink, Roberto Cornacchia, Arjen P. de Vries
2010 Conference and Labs of the Evaluation Forum  
The CLEF IP 2010 PAC task enabled us to correct some experiments and obtain better results, basically using the same techniques (almost the same BM25-category strategy as used last year) and improved strategy  ...  The results are now comparable with other participants.  ...  Creating a full run over 2000 topics took about 12 hours. A SQL dump of the resulting database is roughly 300GB uncompressed in size (81GB bzipped).  ...
