Abstract

The invention provides a multi-modal news recommendation method and device based on a multi-head self-attention neural mechanism, and the method comprises the steps: collecting data information, including news data, feature data and trace data; fusing the data information into uniform news features based on a multi-component feature cross model of a view-level attention mechanism, a hot news real-time prediction technology of streaming data and a multi-modal information fusion technology of intelligent frame extraction; and taking the unified news features as model input, and completing a personalized accurate recommendation function through a user interest representation model and in combination with a highest future influence strategy. According to the scheme, the user cold start problem is effectively relieved, feature collection and fusion are conducted on multi-modal information in news through multi-modal information fusion, high-order cross feature mining and user interest characterization learning are conducted through a multi-head self-attention mechanism, time sequence weights are given to the news according to the highest future influence strategy and real-time news hot spot mining, and the user interest characterization learning efficiency is improved. And participating in final user recommendation.

Description

technical field [0001] The invention belongs to the field of artificial intelligence. Background technique [0002] In today's information explosion and fast-paced society, more and more users acquire knowledge and information through online reading. In order to help users find correct and relevant content within a limited time, news recommendation technology emerges as the times require. News recommendation aims to solve the problem of information overload by making personalized recommendations to users through the computer's powerful computing power and high-efficiency feature matching. At present, there are mainly two forms of news recommendation methods: (1) filtering based on collaboration; (2) filtering based on content. [0003] (1) Based on collaborative filtering. Using the preferences of groups with similar interests and common experience to recommend information that users are interested in, individuals give a certain degree of response (such as scoring) to the...
