Problems solved by technology

[0002] Under suitable conditions, recommending suitable news to suitable users requires the use of recommendation technology, and the core of recommendation technology is the recommendation algorithm. The recommendation algorithm usually used in the prior art can only recommend from a single direction. However, with the continuous increase in the number of users and the continuous expansion of the project scale, the use of a single-direction recommendation algorithm can no longer solve the problems faced, and there will be problems of cold start and concept drift

Abstract

The invention relates to a data information recommendation method and device, terminal equipment and a storage medium. The method comprises the following steps: obtaining different types of data contents included in target demand information in response to the target demand information input by a user; determining an initial feature model according to the target data contents corresponding to different types; obtaining implicit behavior information of the user, and determining a user behavior model according to the implicit behavior information of the user; determining a user interest model according to the initial feature model and the user behavior model; determining a recommended data information set according to the target data content and the user interest model; determining target data information according to a D-S evidence theory and the recommended data information set, recommending the target data information to the user, mining dominant demands of the user by adopting an initial feature model in combination with the feature vector of the target data content, and solving a cold start problem; meanwhile, hidden demands of users are mined through user behavior characteristics, and the concept drift problem is solved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data information recommendation method, device, terminal equipment and storage medium. Background technique [0002] Under suitable conditions, recommending suitable news to suitable users requires the use of recommendation technology, and the core of recommendation technology is the recommendation algorithm. The recommendation algorithm usually used in the prior art can only recommend from a single direction. However, with the continuous increase in the number of users and the continuous expansion of the project scale, the use of a single-direction recommendation algorithm can no longer solve the problems faced, and there will be problems of cold start and concept drift. Contents of the invention [0003] The present invention intends to provide a data information recommendation method, device, terminal equipment and storage medium to solve the deficiencies in th...
