ICTNET at Web Track 2012 Ad-hoc Task

Abstract

In this paper, we report our experiments at Ad-hoc task, Web Track 2012. In this year, we attempt to use new web parser with noise elimination. The Conditional Boolean BM25 was used as major ranking function. We also introduce Learning-To-Rank to combine multiple features together for ranking, but the performance was poor due to the low quality of training data.
