A MECHANISM FOR MULTIMODAL PRESENTATION PLANNING BASED ON AGENT COOPERATION AND NEGOTIATION

A multimodal presentation planning mechanism must take into considerat ion the structure of the discourse and the constraints imposed by disc ourse relations. This requires that different processes that perform m ultimodal presentation planning be able to communicate with each other . In this article, we introduce a multiagent architecture based on the blackboard system that satisfies this requirement. In addition, we de scribe a constraint propagation mechanism that transfers plan constrai nts from one level of the presentation planning process to the next, a nd we discuss the cooperation and negotiation processes between modali ty-specific agents in a prototype system that implements the multiagen t planning mechanism.
