Abstract

Session-based recommendation is a challenging field in the research network-based behavior modeling, mainly due to the complex transfer of user interests between items and the limited information. The previous methods model the session as a sequence or a graph, which takes into account the role of time attention in session-based recommendation and achieve satisfactory performances, they still ignore the latent relationship between user interest transfer and item category. In this study, we propose a category attentive graph neural network (CAGNN) model for session-based recommendation. According to the item category, the category attention is embedded into the latent vector of the items to adaptively capture different user interests, which effectively improves the expressiveness and performance of the model. The numerical results of two real datasets show that CAGNN outperforms the state-of-the-art session-based recommendation methods.
