TLDR
The emphasis in this paper will be on the analysis of individual utterances at various levels in a natural language dialogue system which interfaces a database containing information about theatre performances in a certain city or region.Abstract:
SCHISMA is a joint research project of KPN (Royal PTT Nederland) and the University of Twente. The
project aims at providing a natural language dialogue system which interfaces a database containing
information about theatre performances in a certain city or region. The interface should make it possible
to ask about performances in general, to tune in to a specific performance and, if desired, make a
reservation for this performance. Research until now has concentrated on various aspects of realising
such a theatre information and booking system. Among these aspects are the building of a Wizard of Oz
environment for the acquisition of a corpus of dialogues for this domain, analysis and tagging of the
dialogue corpus, recognition of domain-specific concepts (actors, authors, plays, dates, etc.), syntactic
analysis and dialogue modelling. The emphasis in this paper will be on the analysis of individual
utterances at various levels. Most important for the project are short and medium term goals of delivering
prototype systems that allow demonstration of the system and evaluation of the design choices. Due to
these goals the project does not strive at incorporating advanced but isolated research results on discourse
models and syntactic and semantic analysis. Rather we investigate how to identify user preferences and
how to embed systems like these in a more comprehensive environment of information and transaction
services.read more

Speech Acts: An Essay in the Philosophy of Language
TL;DR: A theory of speech acts is proposed in this article. But it is not a theory of language, it is a theory about the structure of illocutionary speech acts and not of language.
