... TREC doesn’t supply relevant documents and answer patterns for them. Therefore, we will evaluate 203 TREC04 ques- tions. Five answer extraction methods are evalu- ated for comparison: • Density: ... methods perform on the two question sets. The results indicate that our method achieves better performance than the other syntactic-based methods on both question sets. Especially for more d...
