    A User Recommendation System Based on Graph Neural Network and Contextual Behavior

  • Original language description

    Today, recommendation systems are an integral part of e-commerce services on the Internet. In connection with their development, neural networks have become the most used approach to recommender systems. In our post, we will demonstrate the use of graph neural networks to create a recommender system. E-commerce systems can be modeled using a bipartite interaction graph. There are two essential parts to this chart, users and items. In our model, context is added to them and integrated into the mentioned parts of the bipartite graph using the theory of hypothetical functions. Different elements of a bipartite graph can interact using edges. Therefore, modeling the interaction of elements can be transformed into modeling the interaction of nodes on the corresponding graph. We implemented a recommender system model in Python and used relevant libraries, which we tested on standard datasets. These experiments showed the good ability of our model for recommendations. We used the root mean square error (RMSE) and mean absolute error (MAE) indicators.
