Research on the Design and Application of Implicit Semantic Model in Bundle Recommendation Method

Abstract

The recommendation system has been studied for a long time. Data of more users and commodities has been used to improve precision of the recommendation system. However, few studies are on utilization of bundling information. The bundling information refers to the inherent connection of the commodities, and depended by objective properties of commodities. This paper adds bundling information to the recommendation method based on traditional implicit semantic model and collaborative filtering method. This paper sets the bundling coefficient to show the connection degree between commodities and recommended decisive factors. Experiment shows the precision of recommendation could be improved with bundling information in specific environment through changing bundling coefficient.
