Abstract

The invention provides an identifier classification method, and belongs to the technical field of internet content recognition and classification. The method comprises the steps of obtaining a labeledsample set, the labeled sample set having vectors of known class digital content of known class objects and vectors of known class identifiers of different hierarchies of the known class digital content; and obtaining a target class sample set and a target set with identifiers to be classified, and identifying the identifiers to be classified in the target set as target classes the same as the target class sample set according to a transfer learning method in combination with the labeled sample set.

Description

technical field

[0001] The present invention relates to the technical field of Internet content identification and classification, in particular to an identifier classification method, an identifier application method, an identifier classification system, a classification device and a computer-readable storage medium. Background technique

[0002] With the popularization and rapid development of the Internet, users are constantly looking for practical, practical and affordable information on the Internet. Users have more and more extensive demands for Internet information and hope that the information will become more and more abundant. Traditional web search is being upgraded to content search. The first generation of large and comprehensive horizontal websites (also known as comprehensive websites) can no longer fully meet the needs of users, and focus on specific areas or vertical resources that provide specific services. As a new bright spot of the Internet, it is attrac...

Examples

Embodiment 1

[0106] An embodiment of the present invention provides a method for classifying identifiers, the method comprising:

[0107] Firstly, obtain a labeled sample set, wherein the labeled sample set has a vector of known class digital content of known class objects and a vector of known class identifiers of different levels of the known class digital content; secondly, obtain The target class sample set and the target set with the identifier to be classified are obtained, and the identifier to be classified in the target set is identified as the same target class as the target class sample set according to the transfer learning method in combination with the labeled sample set.

[0108] The method also specifically includes:

[0109] S1) Obtain a labeled sample set, wherein the labeled sample set has a vector of known digital content of known type objects and a vector of known class identifiers of different levels of the known digital content;

[0110] An object can have many digi...
