Abstract

The embodiment of the invention discloses a method and device for generating information. A specific embodiment of the method comprises the steps of obtaining historical behavior data of a target userin a preset historical time period; based on the obtained historical behavior data, generating a feature vector used for representing user features of the target user; inputting the feature vector into a pre-trained product identification model to obtain a product vector as a reference product vector, the reference product vector being used for indicating a product in which the target user is interested; searching the reference product vector by using a pre-constructed vector search engine to obtain a first target number of result product vectors; and obtaining product information of productscorresponding to the first target number of result product vectors to form a product information set. According to the embodiment, the generation modes of the product information set are enriched, and the diversity of information generation is improved.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of computer technology, and in particular to methods and devices for generating information. Background technique [0002] Personalized recommendation is to recommend information that the user is interested in based on the user's interest characteristics, which can help the user quickly locate the content of interest and improve user experience. [0003] In practice, due to the large number of products on the market, it is impossible to evaluate and calculate all products when recommending personalized products to users online in real time. At present, the general practice of personalized recommendation is to construct a personalized product candidate set for each user in advance, and then, when implementing online recommendation, products can be selected from the product candidate set for recommendation. Contents of the invention [0004] Embodiments of the present disclosure propose methods...
