Reciprocal Rank)による検索精度で，従来手法が0.429であったのに対し，今回の手法では0.597に向上した．","subitem_description_type":"Other"}]},"item_4_description_8":{"attribute_name":"論文抄録(英)","attribute_value_mlt":[{"subitem_description":"We have

Failure analyses of our system showed that speech recognition errors were fatal for answer type recognition and therefore for the final Mean Reciprocal Rank (MRR) performance, espe-cially with numerical factoid questions. We therefore propose a new method which is robust to speech recognition errors.
