Embodiment Construction

[0068] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0069] like figure 1 As shown, the automatic generation algorithm of microblog user tags based on biclustering is based on Wikipedia, using biclustering algorithm to construct semantic ontology, locating the corresponding words of text words in microblog, and disambiguating the ambiguous words. Accurately correspond to categories for words and generate high-accuracy labels for users.

[0070] The present invention mainly comprises the following steps:

[0071] 1) On the basis of Wikipedia, a semantic ontology is constructed using a bi-clustering algorithm;

[0072] 2) Obtain the microblog information of microblog users and perform preprocessing to obtain the bag of words model;

[0073] 3) U...

Abstract

The invention discloses an automatic generating algorithm of a microblog user label based on biclustering. The automatic generating algorithm is characterized by comprising the following steps: a semantic ontology is constructed by adopting a biclustering algorithm on the basis of Wikipedia; microblog information of a microblog user is obtained and preprocessed, so as to obtain a bag-of-words model; words are extracted from the bag-of-words model by utilizing the semantic ontology, and disambiguation is performed on ambiguous words; the words subjected to disambiguation are mapped to corresponding category nodes in the Wikipedia, so as to construct a category subtree; the user label is collected by aiming at the microblog content of the user; finally, the user label is generated by adopting a voting strategy. According to the automatic generating algorithm, the semantic ontology is constructed by adopting the biclustering algorithm on the basis of the Wikipedia, equivalents of text words in microblog are positioned, the disambiguation is performed on the ambiguous words, categories accurately correspond to the words, and the label with high accuracy is generated for the user.

Description

technical field [0001] The invention relates to the technical field of social search, in particular to an algorithm for automatically generating microblog user tags based on double clustering, which is suitable for social search. Background technique [0002] With the development of network technology, the information resources accumulated by the Internet in various application fields have increased rapidly, and users have gradually become the main body of information. interactive. People use various terminals to access social networks anytime and anywhere for entertainment, to publish their own living conditions, to comment on some news, etc. Social networks have penetrated into all aspects of people's life, study, and work. [0003] "Weibo" is the abbreviation of Microblog. It is an information sharing, dissemination and acquisition platform based on user relationships. Users can form personal communities through WEB, WAP and various clients, and update information with t...
