GMAT: A Graph Modeling Method for Group Preference Prediction

Preference prediction is the building block of personalized services, and its implementation at the group level helps enterprises identify their target customers effectively. Existing methods for preference prediction mainly focus on behavioral interactions to extract the associations between groups and products, ignoring the importance of other auxiliary records (e.g., online reviews and social tags) in association detection. This paper proposes a novel method named GMAT for group preference prediction, aiming to collectively detect the sophisticated association patterns from user generated content (UGC) and behavioral interactions. In doing so, we construct a tripartite graph to collaborate these two types of data, and design a deep-learning algorithm with mutual attention module for generating the contextualized representations of groups and products. Extensive experiments on two real-world datasets show that GMAT is superior to other baselines in terms of group preference prediction. Additionally, GMAT is able to improve prediction accuracy compared with its different variants, further verifying the proposed method’s effectiveness on association pattern detection.
