The importance of intention in conversation has been considered by many researchers in artificial intelligence and psychology. However, most models of conversation have been limited to pursuing the transfer of knowledge between the system and a user. We propose that conversational goals can address communication at a number of other levels such as the conversats emotions, their relationship, and their attitudes. MAGPIE Multiple Active Goal Processor in Interactive Exchanges is a computer model of a conversant that acquires and pursues conversational goals at a number of levels, including the goal of seeking dominance in its relationship with the other conversant. At the heart of the program is a set of tracking procedures, each of which monitors a specific level of communication flow in a conversation. These procedures are coupled with a conversational goal planner which generates responses that simultaneously pursue a number of goals. Currently, MAGPIE is able to model a wife during a short marital dispute with her husband. Normative data form human subjects is presented which supports the conversational goals proposed in our analysis. Author
