Abstract

The embodiment of the invention belongs to the technical field of artificial intelligence, can be applied to the field of smart government affairs and / or medical science and technology, and relates toa news recommendation method and device, computer equipment and a storage medium, and the method comprises the steps: inputting a received news document into a semantic extraction model of a preset initial recommendation model, and obtaining a semantic feature representation vector; calculating an entity feature representation vector of a single entity in the news document; aggregating all the entity feature representation vectors to obtain an aggregated representation vector; processing the aggregation representation vector, the semantic feature representation vector and a preset user vectorto obtain a prediction result; and calculating a loss function value of the initial recommendation model, iteratively training the initial recommendation model until the initial recommendation modelconverges, obtaining a trained recommendation model, and recommending news to the user based on the trained recommendation model. The trained recommendation model can be stored in a block chain. According to the invention, the news recommendation dimension is enhanced.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, in particular to a news recommendation method, device, computer equipment and storage medium. Background technique [0002] At present, personalized recommendation systems are widely used in various industries such as the Internet, e-commerce, life, and entertainment. Compared with traditional search systems, users do not need to actively input target information or queries, but the system automatically matches appropriate news messages based on user portrait information and scene context information and pushes them to users. This method greatly enhances user information. Acquisition efficiency and user experience, which will help increase the user scale of the product. [0003] There are many kinds of news recommendation methods, including news recommendation methods based on item-based collaborative filtering algorithm, news recommendation method based on latent seman...
