Modeling Performance in Open-Domain Dialogue with PARADISE

Walker, Marilyn, Harmon, Colin, Graupera, James et al.

Understand

There has recently been an explosion of work on spoken dialogue systems, along with an increased interest in open-domain systems that engage in casual conversations on popular topics such as movies, books and music.

  • These systems aim to socially engage, entertain, and even empathize with their users.
  • Since the achievement of such social goals is hard to measure, recent research has used dialogue length or human ratings as evaluation metrics, and developed methods for automatically calculating novel metrics, such as coherence, consistency, relevance and engagement.
  • Here we develop a PARADISE model for predicting the performance of Athena, a dialogue system that has participated in thousands of conversations with real users, while competing as a finalist in the Alexa Prize.
