Abstract

The invention discloses a cross-platform theme association method, a cross-platform theme association device and equipment thereof, wherein the method comprises the steps of: obtaining the historical information of a user on a first platform; inputting the historical information into the theme model of the first platform, so that first interest feature information of the user is obtained; and inputting the first interest feature information into a cross-platform association model, so that second interest feature information is obtained, and thereby, recommending the information to the user on a second platform based on the second interest feature information. Thereby, the interest difference of the user on the different platforms can be considered; the problem that cross-platform data is inconsistent can be solved; and thus, cross-platform association based on the user is realized better.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a cross-platform theme association method, device and equipment thereof. Background technique [0002] Usually, cross-platform theme association is required for user convenience. In related technologies, user-based cross-platform topic association methods mainly include: 1) learning the direct linear mapping function between user features of different platforms to realize cross-platform association; 2) linearly mapping user features of different platforms to a common latent space , based on which cross-platform correlation is achieved. [0003] However, the above methods consider the topical interest shown by users on different platforms to be consistent, thus enabling cross-platform association based on users. But in fact, users have different interests on different platforms, which they do not take into account. In addition, they use linear mapping functions, which have...
