Overview Of The 2009 Qa Track: Towards A Common Task For Qa, Focused Ir And Automatic Summarization Systems
INEX'09: Proceedings of the Focused retrieval and evaluation, and 8th international conference on Initiative for the evaluation of XML retrieval（2010）
摘要
QA@INEX aims to evaluate a complex question-answering task In such a task, the set of questions is composed of factoid, precise questions that expect short answers, as well as more complex questions that can be answered by several sentences or by an aggregation of texts from different documents Question-answering, XML/passage retrieval and automatic summarization are combined in order to get closer to real information needs This paper presents the groundwork carried out in 2009 to determine the tasks and a novel evaluation methodology that will be used in 2010
