摘要：
At present, the traditional recommendation algorithm based on collaborative filtering has poor performance in the face of sparse data and cold start. However, the recommendation system assisted by knowledge graph can effectively alleviate this problem. Supplemented by attention mechanism, a neural collaborative recommendation algorithm combining attention mechanism and knowledge graph is designed. Then the attention mechanism is used to learn and aggregate the higher-order potential relationship information in the knowledge graph. At the same time, the user’s final preference is obtained through gated recurrent neural network training based on the user’s long-term and short-term interest preferences. Finally, the collaborative filtering method is used to generate the recommendation list. Through experiments on MovieLens-1M and Amazon-Book datasets, the recommended recall rate, accuracy rate, hit rate and NDCG evaluation indicators are all improved, which validates the effectiveness of the proposed method. © 2023 The Author(s).
