Information sorting method and device, electronic equipment and computer readable medium

Abstract

The embodiment of the invention discloses an information sorting method and device, electronic equipment and a computer readable medium. The method comprises the steps of obtaining a candidate information set for a target user; extracting feature information corresponding to each part of candidate information in the candidate information set; respectively inputting each part of feature informationinto a pre-trained sorting model, obtaining the score of each part of candidate information; wherein the sorting model comprises a multi-task network and a fusion network, the multi-task network comprises a plurality of sub-task networks with dependency, the different sub-task networks are used for predicting the probability of occurrence of different user behaviors, and the fusion network is connected with the sub-task networks and used for predicting scores of candidate information based on the probability predicted by the sub-task networks; and sorting the candidate information based on the scores. According to the embodiment, the accuracy of the information sorting result is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular to an information sorting method, device, electronic equipment, and computer-readable medium. Background technique [0002] With the development of computer technology, it is necessary to send information to users in more and more scenarios. For example, when a user searches for a certain search term, information related to the search term can be sent to the user; when the user browses the e-commerce page, some promoted products can be pushed in the product information they browse information etc. Before sending information, it is usually necessary to sort the recalled candidate information, so that candidate information more relevant to user needs can be preferentially sent to the user. [0003] In the prior art, the user's interest relationship to certain information is usually learned from user behavior data through a ranking model, and the can...
