The modelling of each participant's range of information about the dialog, and its interaction with the others, is represented by commitments - placed in a commitment store - generated during the conversation process. Clichés - conversation stereotypes - are state transition machines that control the sequencing of dialog events in a conversation between two participants. The notion of contract - mapped to Winograd’s Conversation for Action diagram - is presented as an example of the framework’s ability for representing conversation clichés for cooperative work. Keywords Clichés, Commitment, Contract, Cooperative Work, Dialog, Conversation for Action 1. Introduction Cooperation requires conversation. Conversations, particularly bureaucratic ones, tend to be structured and repetitive. Clichés are state transition machines that control the sequencing of dialog events between two participants in a conversation. A cliché restrains the unfolding of a conversation. Hence, it is possible to use specific clichés for reaching specific results like the opening of a current account or buying some article over the phone using a credit card. This paper proposes the use of conversation clichés for structuring cooperative work. These clichés are built using the dialog primitives of ACCORD. In this framework,a dialog is a sequence of dialog events; a dialog event is a tuple consisting of a locution, and the speaker and the hearer of that locution. A locution is a locution modifier applied to one or more sentences. In section 2 of this work ACCORD is described. The notion of cliché is introduced in section 3. In section 4, the notion of contract - mapped to Winograd’s Conversation for Action diagram (Winograd 88) - is presented as an example of the framework’s ability for representing conversation clichés with a view to cooperative work. Finally, the conclusion and future extensions of this work are presented in section 5. 2.
