Embodiment Construction
[0025] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0026] figure 1 It is a flowchart of a public identification classification method provided by the embodiment of the present invention. see figure 1 , the method flow provided by the embodiment of the present invention includes:
[0027] 101. Determine multiple public identities associated with user behaviors to obtain a list of public identities.
[0028] 102. According to the feature vector of each public identifier, cluster all the public identifiers in the public identifier list to obtain multiple clustering results.
[0029] 103. Based on the description information of each public identifier, determine among the plurality of clustering results a clustering result of the first type whose clustering purity is greater than a prese...

The invention discloses a public sign classification method and device, and belongs to the technical field of networks. The public sign classification method includes: determining a plurality of public signs associated with a user behavior, and acquiring a public sign list; clustering all the public signs in the public sign list according to a feature vector of each public sign to obtain a plurality of clustering results; determining first type clustering results having the clustering purity degree greater than a preset threshold in the plurality of clustering results on the basis of description information of each public sign; and re-classifying public signs in second type clustering results according to the first type clustering results, wherein the clustering purity degree greater of the second type clustering results is less than the preset threshold. The public signs are automatically classified on the basis of the user behavior and the description information of the public signs without manual operation, lots of labors can be saved, and the classification effect of the public signs is good.
Description
technical field [0001] The present invention relates to the field of network technology, in particular to a public identification classification method and device. Background technique [0002] As an application program that provides information interaction services such as voice, video, pictures, and text for smart terminals, Internet applications are widely used by users due to their advantages of sending voice, video, pictures, and text across communication operators and operating system platforms. of favor. With the improvement of Internet application functions, developers or merchants apply for a public logo on the Internet application platform. Through this public logo, developers or merchants can implement text, pictures, audio, video, etc. on the Internet application platform. Push information to the majority of users in an all-round way, communicate or interact with the majority of users, etc. Under normal circumstances, the industry category to which the public l...
