Embodiment 1

[0056] Embodiment 1 discloses a cross-platform user identification method, refer to figure 1 , the method may include the following steps:

[0057] S101: Obtain the first message segment of the first user account on the first platform, and acquire the second message segment of the second user account on the second platform, wherein the first message segment is published by the first user account A message segment composed of all messages within the first preset time period, and the second message segment is a message segment composed of all messages published within the first preset time period in the second user account.

[0058] In this embodiment, the method of the present invention is described by taking the identification of whether the Sina Weibo account and the Tencent Weibo account belong to the same user as an example.

[0059] Specifically, the API (Application Programming Interface, Application Programming Interface) specially provided by Sina Weibo can be used to ...

Embodiment 2

[0093] In the second embodiment, refer to figure 2 , the cross-platform user method may also include the following steps between steps S102 and S103:

[0094] S106: Perform filtering processing on the first message segment in the participle form and the second message segment in the participle form respectively.

[0095] Among them, this step includes:

[0096] performing stop word removal and low frequency word removal processing on the first message segment in the word segmentation form; and performing stop word removal and low frequency word removal processing on the second message segment in the word segment form.

[0097] Specifically, social platform users often publish more messages and frequent times, for example, Weibo users publish more Weibo messages, etc., resulting in too large message texts collected. In this embodiment, in order to improve cross-platform user Recognition speed, remove stop words and remove low-frequency words (for example, filter out word seg...

Embodiment 3

[0099] In the third embodiment, refer to image 3 , the cross-platform user identification method may also include:

[0100] S107: Utilize the set number of message segment sample pairs in advance, and perform cross-platform user identification training on the maximum entropy classification method based on the feature similarity of each message segment sample pair to obtain a maximum entropy classifier, so as to realize the adoption of the maximum entropy classifier. The entropy classifier identifies whether the first user account on the first platform and the second user account on the second platform belong to the same user.

[0101] Wherein, the two message segments contained in the message segment sample pair respectively belong to two accounts of different platforms, and the two accounts are accounts of the same user or accounts of different users, and the message segments contained in the message segment sample pair The publishing time of is within the second preset tim...

Abstract

The invention discloses a cross-platform user identification method and a cross-platform user identification system, which take the importance of use messages in social platforms into full consideration and identify whether a user is the same user according to the similarity of personalized information, such as user knowledge, interests, preferences, writing styles and wording habits, reflected by the user messages in two accounts of different platforms within a corresponding period of time. Specifically, the method comprises the steps that obtains message contents, which are released within a preset period of time, in the two accounts of the different platforms are obtained, word segmentation and feature extraction treatment are carried out on the message contents of the two accounts, and on the basis, by utilizing the similarity between the segmented word features of the messages of the two accounts, whether the two accounts of the different platforms belong to the same user is identified. Thus, the cross-platform user identification method and the cross-platform user identification system solve the problem of how to identify the same user on different social platforms, and further provide support for the analysis of cross-platform data of the same user.

Description

technical field [0001] The invention belongs to the fields of natural language processing technology and social network, and in particular relates to a cross-platform user identification method and system. Background technique [0002] In recent years, with the rapid development of social networks, various types of Micro-blogs, such as Sina Weibo, Tencent Weibo, Twitter, Facebook, etc., are increasingly favored by users. [0003] Because Weibo has both media communication characteristics and social network characteristics, it has attracted many researchers to analyze and study Weibo data. At present, more and more users have Weibo accounts on different platforms at the same time. For example, users have Sina accounts and Tencent accounts at the same time. It is conducive to comprehensive analysis and in-depth mining of user interests and preferences, which is more conducive to enterprises to formulate personalized marketing strategies and carry out accurate advertising; at ...
