Task oriented dialogues following a description of the task.

From medical domain example:

————

Ask what symptoms the patient is feeling. For each symptom ascertain symptom duration, if it is worsening or improving, if there alleviating or aggravating factors. For symptoms with uncertain location assert symptom location.

Doctor: Hi, what brings you in here today?

Patient: I’ve been having a sore throat and pain in my face for the past week.

Doctor: [start generation]

—————

In particular such tasks (after multiple dialogue turns) are hard because one needs to be coherent through the conversation. This is something eg davinci-2 is much better than davinci.
