Abstract

The invention relates to a data determination method and device, electronic equipment and a storage medium, which can describe user interests from multiple aspects and improve the recall rate. Relates to the technical field of big data processing. The method comprises the steps of obtaining interaction information of a target object for a target resource; determining features of the target object according to the interaction information; the features of the target object comprise features of multiple dimensions; determining a plurality of groups of weight coefficients, wherein each group of weight coefficients comprises a plurality of weight coefficients corresponding to the features of the plurality of dimensions; performing weighting processing on each group of weight coefficients and the features of the target object to obtain a plurality of vectors of the target object; wherein each vector of the target object corresponds to a group of weight coefficients; and searching candidate resources of which the correlation meets a preset requirement for each vector of the target object, and determining a data recall result corresponding to the target object according to the candidate resources corresponding to each vector in the plurality of vectors of the target object.

Description

technical field [0001] The present disclosure relates to the technical field of big data processing, and in particular to a data determination method, a data determination device, electronic equipment, a computer-readable storage medium, and a computer program product. Background technique [0002] Data recall refers to the process of determining a part of data that is most interesting to users from a database with millions of data. Specifically, the data may include pictures, texts, videos, etc., and may also include target resources, such as advertisements, commodities, etc. The determined data will be sorted and displayed to users, which plays a vital role in data retrieval and information promotion. [0003] In related technologies, data recall mainly adopts: vectorization-based recall schemes, label-based recall schemes, and feature-based recall schemes. Among them, the recall scheme based on vectorization learns a vector expression for the user and the advertisement ...
