An Overview of Question and Answering Challenge (QAC) of the next NTCIR Workshop

Abstract

In this paper we will propose the question and answering task, called Question and Answering Challenge (QAC), and its first evaluation. This will be carried out as a sub-task of NTCIR3 Workshop scheduled in October 2002. In QAC, we aimed to encourage the development of practical Q&A systems in a general domain and focus on research of user interaction and information extraction. User interaction technology leads to actual interaction between computer and person. In actual Q&A between people, there will typically be several interactions in order to confirm the intention of the questions and so on. Information extraction that works in general domain is also an important technology in order to realize real Q&A system.
