Open-Domain Conversational Agents: Current Progress, Open Problems, and Future Directions

arXiv 2006.12442 ↗First posted 22 Jun 2020cs.CL cs.AIcited by 34

Not on the map. Why?

Abstract (arXiv)

We present our view of what is necessary to build an engaging open-domain conversational agent: covering the qualities of such an agent, the pieces of the puzzle that have been built so far, and the gaping holes we have not filled yet. We present a biased view, focusing on work done by our own group, while citing related work in each area. In particular, we discuss in detail the properties of continual learning, providing engaging content, and being well-behaved -- and how to measure success in providing them. We end with a discussion of our experience and learnings, and our recommendations to the community.
