Neural Generation Meets Real People: Building a Social, Informative Open-Domain Dialogue Agent

Chi, Ethan A.; See, Abigail; Chiam, Caleb; Chang, Trenton; Kenealy, Kathleen; Lim, Swee Kiat; Hardy, Amelia; Rastogi, Chetanya; Li, Haojun; Iyabor, Alexander; et al (September 2022, Proceedings of the 23rd Annual Meeting of the Special Interest Group on Discourse and Dialogue)

We present Chirpy Cardinal, an open-domain social chatbot. Aiming to be both informative and conversational, our bot chats with users in an authentic, emotionally intelligent way. By integrating controlled neural generation with scaffolded, hand-written dialogue, we let both the user and bot take turns driving the conversation, producing an engaging and socially fluent experience. Deployed in the fourth iteration of the Alexa Prize Socialbot Grand Challenge, Chirpy Cardinal handled thousands of conversations per day, placing second out of nine bots with an average user rating of 3.58/5.
