Abstract. Message semantics are traditionally defined in terms of mental states, which is a trend that is criticized for assuming the sincerity and cooperativeness of agents. To circumvent these limitations, several proposals have been put forth to define the semantics of messages using social commitments. We follow this trend and present a conversational model where the meaning of messages is based on their use as coordinating devices advancing conversations that advance the state of social commitments and the state of the activities in which agents participate.
