Evaluating the effect of information presentation strategies on task success and user perceptions
Year: 2008
Type: conference-paper
Abstract: In this paper we present results of a Wizard-of-Oz (WoZ) experiment comparing two approaches to information presentation in spoken dialogue systems. We show that the user-model based summarize- and-refine (UMSR) approach leads to increased task efficiency in comparison with the summarize-and-refine (SR) approach. Moreover, user ratings on four evaluation criteria demonstrated a clear preference for recommendations based on the UMSR approach to information presentation.
