Abstract

The embodiment of the invention discloses an information recommendation method, device and equipment and a medium, and relates to the technical field of information. The method comprises the followingsteps of determining at least one historical user similar to a target user as a reference user according to the user characteristics; taking the target class article associated with the historical behavior of the reference user as a candidate article; determining the weight of the candidate article according to the historical behavior and historical behavior weight of the reference user on the candidate article and the similarity between the reference user and the target user; and according to the weight of the candidate item, recommending a target item to a target user. According to the information recommendation method, device and equipment and the medium provided by the embodiment of the invention, the personalized recommendation of the credit card information to the user is realized,so that the personalized demand of the user on the credit card is met, and the information recommendation accuracy is further improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of information technology, and in particular, to an information recommendation method, device, device and medium. Background technique [0002] Users handle credit cards with the characteristics of low processing frequency and weak features. Because the processing frequency is low, most of the users facing us are new users. The cold-start recommendation problem caused by the lack of historical information for new users is a difficulty in the entire recommendation field. Weak features mean that it is difficult to make direct recommendations based on user attributes. Cold-start recommendation refers to the inability to recommend credit cards to users based on historical information. [0003] The credit card recommendation method in the existing mainstream card application platforms is more based on the popularity of credit card clicks or the amount of income. However, because the needs of use...
