Abstract

The invention provides an information cross-domain parallel sequence recommendation method based on shared account, a medium and equipment. The method comprises the steps: extracting watching sequences of a given account in different fields, and carrying out the coding of the watching sequences, and obtaining the mixed representation of the given account in a single field; identifying different user behaviors by learning the hybrid representation, and filtering out information which may be useful for another domain; migrating the useful information of each field to other corresponding fields;and integrating useful information filtered in different fields, evaluating each piece of related information, and recommending the related information to the corresponding account according to an evaluation result. The problems of cold start and data sparsity frequently appearing in a recommendation system are solved.

Description

Technical field [0001] The present disclosure belongs to the field of information processing, and specifically relates to a method, medium, and device for recommending a cross-domain parallel sequence of information based on a shared account. Background technique [0002] The statements in this section merely provide background information related to the present disclosure, and do not necessarily constitute prior art. [0003] Sequence recommendation is a method that captures short-term or long-term interests of users based on users' browsing or purchase records in a certain period of time. Among them, the user's records have a clear time sequence, and the records in the same time period may reflect the same interests and purposes of the user. [0004] Shared account recommendation is a question raised in response to multiple users sharing one account. In recent years, it has become common for family members to share accounts on various platforms. Multiple users under an account ma...
