User identifier identification method and device, electronic equipment, storage medium and product

The invention relates to the technical field of data processing, and provides a user identifier identification method and device, electronic equipment, a storage medium and a product, and the method comprises the steps: constructing a first data set based on a to-be-processed ID atlas; determining probability information that every two user ID vertexes having an association relationship in the ID atlas to be processed belong to the same user, and second distance information between every two user ID vertexes; determining third distance information based on the first distance information and the second distance information; determining second center vertex serial number information between every two user ID vertexes; performing information screening on the third distance information to obtain fourth distance information; based on the fourth distance information and the second center vertex serial number information, performing information updating on the first data set to obtain a second data set; and if all the user ID vertexes in the second data set meet the target condition, performing user identifier identification based on the second data set to obtain a user identifier identification result. According to the invention, the user identifier identification accuracy can be improved.
