User identity association method and device

Abstract

The embodiment of the invention provides a user identity association method and device, and the method comprises the steps: carrying out the polling of an API of a first platform through employing a plurality of APP identities according to the seed ID of a first preset number of first platforms, and obtaining a second preset number of user IDs and a polling record; starting crawler operation of the second platform, scanning the polling record to obtain a corresponding URL, and obtaining an association ID of the URL pointing to the second platform and a non-association ID of the URL not pointing to the second platform in the polling record; extracting features of the association ID and the non-association ID to obtain a first feature vector for training a binary classification model; and obtaining the first platform user ID and the second platform user ID, obtaining a feature vector after feature extraction, and inputting the feature vector into the binary classification model to obtainan identity association result. According to the user identity association method and device provided by the embodiment of the invention, the effective features are extracted from the personal data of the user, the user identity association in the multi-source social network is realized, and the computing resources are saved under the condition of ensuring higher accuracy.

Description

technical field [0001] The invention relates to the technical field of data acquisition and social network, in particular to a method and device for associating user identities. Background technique [0002] Internet technology is changing with each passing day, and the major changes it has caused have given new and meaningful definitions to production and life, and at the same time are promoting more and more people to devote themselves to Internet construction.

Problems solved by technology

[0005] However, in the field of user identity association in multi-source social networks, the acquisition of real user data is the first difficulty. However, the existing methods for user identity association in multi-source social networks often use relatively rich user data, which is difficult for data collection and Handling is very unfriendly, making it difficult to put into practical use
