- Abstract:
-
The algorithm based on collaborative filtering is the most important method in the recommendation system. However, the cold start and data sparsity characteristics limit its recommendation performance. We propose a model that combines a knowledge graph and a lightweight graph convolutional network recommendation system to address the aforementioned issues. The model embeds and propagates multiple items in the knowledge graph to obtain more high-order neighborhood information. It aggregates through a lightweight aggregator to predict the score between users and items. Finally, the experimental findings of MovieLens-20M, Last.FM and Book-Crossing on three real datasets show that compared with other benchmark models, this model can achieve better performance.
