This paper presents ongoing research on computational models for non-cooperative dialogue. We start by analysing different levels of cooperation in conversation. Then, inspired by findings from an empirical study, we propose a technique for measuring non-cooperation in political interviews. Finally, we describe a research programme towards obtaining a suitable model and discuss previous accounts for conflictive dialogue, identifying the differences with our work. | Non-Cooperation in Dialogue Brian Pluss Centre for Research in Computing The Open University Milton Keynes UK b.pluss@open.ac.uk Abstract This paper presents ongoing research on computational models for non-cooperative dialogue. We start by analysing different levels of cooperation in conversation. Then inspired by findings from an empirical study we propose a technique for measuring non-cooperation in political interviews. Finally we describe a research programme towards obtaining a suitable model and discuss previous accounts for conflictive dialogue identifying the differences with our work. 1 Introduction Most approaches to modeling conversation are based on a strong notion of cooperation between the dialogue participants DPs . Traditional models using intentions Cohen and Levesque 1991 dialogue games Power 1979 shared plans Grosz and Sidner 1990 or collaborative problem-solving Blaylock and Allen 2005 explain dialogue situations in which DPs recognise each other s intentions and at least to a certain extent accept each other s goals when deciding on their actions. These assumptions are theoretically grounded as most work in linguistics has considered situations in which DPs share a common goal and cooperate to achieve it by means of conversation Grice 1975 Clark and Schaefer 1989 . They are also practically sound dialogue models are usually implemented in the form of dialogue systems built for the purpose of providing a service to their users e.g. TRAINS Allen and Schubert 1991 . In this scenario failure to cooperate either on the side of the system or of the user is against the premises on which the system is conceived and used. In everyday conversation however a great many situations escape the arguments above. Con sider the following example1 1 Paxman 1 interrupting Did you threaten to overrule him Howard 2 I I was not entitled to instruct Derek Lewis and I did not instruct him. Paxman 3 Did you threaten to overrule him Howard 4 The truth of the matter is .
