Enabling browsing in interactive systems

In this thesis, we examine algorithms for content selection and information presentation that enable browsing as an information-seeking strategy. Our hypothesis is that users who wish to explore the contents of a particular domain might not be satisfied with traditional spoken dialogue systems, in which focal information is not described until a small number of the records comprising the domain are identified through a constraint-elicitation process. Specifically, we hypothesized that users would prefer responses in the form of incremental summaries of the focal information.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
