We have built a demonstrator for spoken human{ machine dialogs. The system is capable to answer inquiries about the InterCity train timetable of the Deutsche Bahn. It evolved from the work done in the ESPRIT project Sundial with four participating Eu-ropean countries (cf. 11]). First experiments have already been described in 1]. In this paper we describe our analysis of real user interaction w...

This paper describes the ESPRIT SUNDIAL project which ran for five years, finishing in August 1993. The objective of the project was to design and build telephone access spoken language interfaces to computer databases. After introducing the aims and objectives of the project, the problem of specifying an interactive system are outlined and the method of Wizard-of-Oz simulation described. The a...

We present DIALEX, an inheritance-based tool that facilitates the rapid construction of linguistic knowledge bases. Simple lexical entries are added to an application-specific DATR lexicon that inherits morphosyntactic, syntactic, and lexico-semantic constraints from an applicationindependent set of structured base definitions. A lexicon generator expands the DATR lexicon out into a disjunctive...

How do circadian rhythms, alarm clocks and the light/dark cycle interact? The concept of social jetlag is informing our appreciation of the tensions and consequences of imposing an artificial temporal order upon our biology.
