Personalized Recommendation Algorithm Based on Implicit Semantic Model
2022 2nd International Conference on Networking, Communications and Information Technology (NetCIT)(2022)
摘要
Collaborative filtering-based recommendation algorithm is widely used in recommendation systems, but it has the problem of data sparsity. This research designed a collaborative filtering algorithm based on implicit semantic model to solve the above problems. The algorithm trains the prediction model by learning the characteristics of user scoring data, and fills it into the original scoring matrix. Then, a collaborative filtering algorithm based on implicit semantic model is used to obtain the prediction score. Through experimental verification, the proposed recommendation algorithm can provide accurate and fast personalized recommendation services.
