INDI: Informationsutbyte i dialog

Information Exchange in Dialogue

Riksbankens Jubileumsfond 1997-0134


Short project description

The project aims to gain a deeper understanding of the detailed mechanisms involved in the exchange of information between participants in a natural language dialogue. Participants come to a dialogue with a certain ``information state'', that is to say, a collection of beliefs, knowledge, desires, goals etc. which are collectively known as ``attitudes'' that the dialogue participant has. A dialogue participant can express one or more of these attitudes in a natural language utterance and thereby succeed in modifying the information state of another dialogue participant. This process of modifying information states during the course of a conversation may be referred to as dialogue dynamics. The research involves developing formal analyses and matching them against real data from spoken language corpora. The investigation also has potential practical import in that there is considerable interest in building computer systems that can interact with humans in more natural dialogue than current technology allows. We have exploited this in other projects such as TRINDI, SIRIDUS, D'Homme and SDS.
