Problems solved by technology

[0006] However, to determine the credibility of a user should be considered comprehensively from various factors. In the prior art, only the characteristics of the user's network information are used for analysis and processing, which inevitably leads to a low accuracy rate of the calculated credibility.

Embodiment Construction

[0079] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0080] Since the existing technology only analyzes and processes one aspect of user network information characteristics when calculating the user credibility, the accuracy of the calculated user credibility is low. Therefore, the inventors of the present application explored quasi-microblogging platforms to find other features that can be used to characterize user credibility.

[0081] During the related research conducted by the inventor of the present application, it was found tha...

Abstract

The application provides a user credibility computation method and device. The user credibility computation method comprises the following steps that feature information of a user to be detected is input into a preset credibility model, wherein the preset credibility model is obtained after training by use of the feature information with calibrated credibility level and takes the feature information as input and the credibility level as output, and the feature information comprises personal information features and network information features; and after computation of the preset credibility model, the credibility level of the user to be detected is outputted. According to the application, the credibility model can comprehensively consider two factors. Compared with the prior art that only one factor is considered, the user credibility computation method has the advantages that as the analysis and treatment factors are increased, the preset credibility model can represent the relationship between the feature information and a classification label more accurately. Therefore, the user credibility computed by the preset credibility model is more accurate.

Description

technical field [0001] The present application relates to the field of network technologies, and in particular to a method and device for calculating user credibility. Background technique [0002] With the gradual development of social networks, there are more and more social platforms, such as Weibo, Instagram, Facebook, Twitter, etc. Since these social platforms have similar functions to microblog platforms, such social platforms are collectively referred to as microblog-like platforms. On quasi-microblog platforms, users can pay attention to each other, leave messages to each other, check their published information and other functions, so such microblog platforms are widely used by users. [0003] As the number of users of quasi-microblog platforms gradually increases, some undesirable phenomena appear on quasi-microblog platforms; for example, some users will post spam or rumor information on quasi-microblog platforms. These undesirable phenomena will lead to disorde...
