| This report describes a dialogue system between an expert system and its users which explores two hypotheses. First, that the dialogue system can communicate meaningfully not only with the person directly interacting with the dialogue system (whom we call the agent) but also (indirectly) with the person reasoned about by the expert system
(the patient) . Second, that a dialogue system can model the domain-related beliefs, preferences and concerns of both its users and generate empathetic responses. These hypotheses have not been explored in previous work on user modeling for dialogue systems. |
