Abstract

The invention discloses an improved commodity recommendation method based on multi-type implicit feedback, and the method comprises the steps: a preparation stage: obtaining a target user and commodity set data from a set e-commerce website, and processing the target user and commodity set data; a learning stage: training a commodity recommendation algorithm by using the target user and commodityset data processed in the preparation stage, and generating a sorting model; and a sorting stage: sorting the recommended commodities by using the sorting model according to the target user and the commodity set data, and outputting a commodity recommendation list.

Description

technical field [0001] The invention relates to the Internet field, in particular to an improved product recommendation method based on multi-type implicit feedback. Background technique [0002] In the era of big data, people need to extract the information they need in a timely and accurate manner. "Personal customization" is particularly important. How to quickly obtain effective information from the huge and complex data, save users' time, and improve users' shopping satisfaction It is one of the important problems that the e-commerce platform urgently needs to solve, and the personalized recommendation system can well meet people's needs because of its good interactivity. [0003] The research on traditional recommendation algorithms mainly focuses on the data of explicit feedback, using the information provided by users for modeling processing. However, with the expansion of the data scale, the problems caused by the limited information that users can provide become mo...
