    <Paragraph position="0"> This paper has presented a new way to formulate system goals in intelligent dialogue systems. It advocates a view-point where the system's fnnctionality is iml)roved by relating the dialogue situation to communication in general. The constraints of rational, cooperative communication p,:ovide the framework in which to deal with contributions: communicators have a joint purpose, they obey communicative obligations and they trust that the partner behaves so that these constraints are tifffilled. Dialogues are dynamic constructions, and contributions are locally planned and realised so that the communicative requirements of the dialogue us a whole are respected.</Paragraph>
    <Paragraph position="1"> Current interests concern the extension of the communicative principles into different activities and agent roles. This contributes to the generality of the model by spelling out specific requirements of different communicative situations. It also enables us to study strategic planning and how different roles affect the obligations that the agents want to obey (e.g. in conflict situations). Work is now in progress to cover other types of task dialogues, and to enhance the impleinentation.</Paragraph>
