| THUIR in TREC2003: HARD Experiments (2008) | |||||||||||||||
Abstract | |||||||||||||||
| In this paper, we describe ideas and related experiments of Tsinghua University IR group in TREC-12 HARD Track. In this track, we focus on an automatic delivering mechanism, which combine the existing IR methods and can provide a quick retrieval solution for the practical environment. The final official evaluation show the old ways perform not well, but we think the experiment data will be helpful in evaluating the new ideas developed by other teams. 1. | |||||||||||||||
