DIALOG SYSTEMS FOR SURVEYS: THE RATE-A-COURSE SYSTEM
Amanda J. Stent, Svetlana Stenchikova, Matthew Marge · 2006
In this paper, we discuss why surveys are an interesting application of spoken dialog systems from both commercial and research perspectives. We then describe a prototype survey spoken dialog system, the Rate-A-Course system. We show how dialog epiphenomena, including the order in which questions are answered and the duration of respondents' answers, can be used to learn information beyond that covered explicitly by survey questions.
