- Abstract summary: We propose a new task of conversational recommendation over multi-type dialogs, where the bots can proactively and naturally lead a conversation from a non-recommendation dialog to a recommendation dialog.
To facilitate the study of this task, we create a human-to-human Chinese dialog dataset emphDuRecDial (about 10k dialogs, 156k utterances)
In each dialog, the recommender proactively leads a multi-type dialog to approach recommendation targets and then makes multiple recommendations with rich interaction behavior.

- Abstract: We propose a new task of conversational recommendation over multi-type
dialogs, where the bots can proactively and naturally lead a conversation from
a non-recommendation dialog (e.g., QA) to a recommendation dialog, taking into
account user's interests and feedback. To facilitate the study of this task, we
create a human-to-human Chinese dialog dataset \emph{DuRecDial} (about 10k
dialogs, 156k utterances), which contains multiple sequential dialogs for every
pair of a recommendation seeker (user) and a recommender (bot). In each dialog,
the recommender proactively leads a multi-type dialog to approach
recommendation targets and then makes multiple recommendations with rich
interaction behavior. This dataset allows us to systematically investigate
different parts of the overall problem, e.g., how to naturally lead a dialog,
how to interact with users for recommendation. Finally we establish baseline
results on DuRecDial for future studies. Dataset and codes are publicly
available at

We introduce a technique for multi-document grounded multi-turn synthetic dialog generation that incorporates three main ideas.
We control the overall dialog flow using taxonomy-driven user queries that are generated with Chain-of-Thought prompting.
We support the generation of multi-document grounded dialogs by mimicking real-world use of retrievers to update the grounding documents after every user-turn in the dialog.

Evaluation [75.60156479374416]
CGoDial is a new challenging and comprehensive Chinese benchmark for Goal-oriented Dialog evaluation.
It contains 96,763 dialog sessions and 574,949 dialog turns totally, covering three datasets with different knowledge sources.
To bridge the gap between academic benchmarks and spoken dialog scenarios, we either collect data from real conversations or add spoken features to existing datasets via crowd-sourcing.
