Three Systems and One Verifier - HOKUM's Participation in QAC3 of NTCIR-5

This paper is a report from collective participation in NTCIR-5 Question Answering Challenge between researchers from Mie University, Hokkaido University and Otaru University of Commerce. Although our results were not impressive, we would like to share our experiences with everyone who think about participating in the challenge but is afraid of his or her lack of experience in the field. Understanding the problems of QA from the practical side was very instructive and gave us a stronger base for future trials. We briefly introduce our preparations and participation then conclude with analysis what can be simply done with freely available tools.
