- Abstract summary: In recommendation dialogs, humans commonly disclose their preference and make recommendations in a friendly manner.
We present a new dataset of 1,001 human-human dialogs for movie recommendation with measures for successful recommendations.
Our analysis shows that sociable recommendation strategies, such as sharing personal opinions or communicating with encouragement, more frequently lead to successful recommendations.

- Abstract: In recommendation dialogs, humans commonly disclose their preference and make
recommendations in a friendly manner. However, this is a challenge when
developing a sociable recommendation dialog system, due to the lack of dialog
dataset annotated with such sociable strategies. Therefore, we present
INSPIRED, a new dataset of 1,001 human-human dialogs for movie recommendation
with measures for successful recommendations. To better understand how humans
make recommendations in communication, we design an annotation scheme related
to recommendation strategies based on social science theories and annotate
these dialogs. Our analysis shows that sociable recommendation strategies, such
as sharing personal opinions or communicating with encouragement, more
frequently lead to successful recommendations. Based on our dataset, we train
end-to-end recommendation dialog systems with and without our strategy labels.
In both automatic and human evaluation, our model with strategy incorporation
outperforms the baseline model. This work is a first step for building sociable
recommendation dialog systems with a basis of social science theories.

Conversational Recommendation Datasets [56.052803235932686]
We propose a novel automatic dataset synthesis approach that can generate both large-scale and high-quality recommendation dialogues.
In doing so, we exploit: (i) rich personalized user profiles from traditional recommendation datasets, (ii) rich external knowledge from knowledge graphs, and (iii) the conversation ability contained in human-to-human conversational recommendation datasets.

We seek to understand the important factors to consider while designing user-centric strategy recommendation systems.
We conducted a human-subjects experiment for measuring the preferences of users with different personality types towards different strategy recommendation systems.
We found that certain personality traits, such as conscientiousness, notably impact the preference towards a particular type of system.

We propose DICR (Dual Imitation for Conversational Recommendation), which designs a dual imitation to explicitly align the recommendation paths and user interest shift paths.
By exchanging alignment signals, DICR achieves bidirectional promotion between recommendation and conversation modules.
Experiments demonstrate that DICR outperforms the state-of-the-art models on recommendation and conversation performance with automatic, human, and novel explainability metrics.

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.
