Speaker Phil Cohen This talk argues that future conversational systems that can engage in multiparty, collaborative dialogues will require a more fundamental approach than existing technology. Specifically, I argue that current transactional dialogue systems, such those of Apple’s Siri, Amazon’s Alexa, Google’s Assistant, and Microsoft’s Cortana, are limited in important ways that will prevent usage in more complex applications. The talk shows how our returning to the plan-based approach to dialogue will provide a stronger foundation by coupling neural network-based semantic parsing with plan-based reasoning. In the last part of this talk, I raise the topic of malevolent dialogue systems that can prey on unwary people and robots. I propose that the subfield of dialogue research investigate defensive dialogue systems that are capable of inferring and responding to an adversary’s manipulative plans and intentions.
