The framework outlines the different actions that users and agents can perform, as well as the key decision points the agent needs to navigate to facilitate a successful and satisfactory conversational search experience.
IterCQR iteratively trains a conversational query reformulation model without human-annotated rewrites, utilizing retrieval signals as a reward to generate queries optimized for off-the-shelf retrievers.
