We limited the scope of our study to the PersonaChat dataset, which is a standard benchmark in dialogue. In PersonaChat, both participants are presented with Personas and asked to roleplay as that person. (e.g. "I love the beach; Horses are my favorite animal; I am on a diet now"). So we restrict ourselves to meeting someone for the first time and trying to learn about them and share a bit about ourselves. The personas that were assigned to the bot and the human were both randomized (from a large, fixed set) and unseen in training data.
