Abstract

The invention discloses a short-text expanding method based on similar-label relation. The short-text expanding method includes introducing similar-label information in a short-text data set into an expanding mechanism, selecting different auxiliary data sets according to different short-text data, expanding short texts based on the similar-label relation and effectively classifying the short texts. The short-text expanding method has the advantages that the problem of short-text classification is solved, noise generated by a conventional characteristic expansion method is lowered and classification accuracy of the short texts is improved; a conventional expansion method based on external corpus information is innovated and improved; the short-text expanding method can be combined with different classifiers, and applicability is high; the short-text expanding method can be applied in the short-text classification problem and is applicable to multi-label classification related to the short texts.

Description

technical field [0001] The invention belongs to the technical field of computer text processing, and relates to a short text expansion technology based on feature expansion. Background technique [0002] With the rapid development of the Internet, a large amount of electronic text information emerges as the times require. Among them, people generate a large amount of short text information by visiting online forums, question-and-answer platforms and social networking sites. Short text refers to text with less content, short text, and indistinct features. Although short texts are short in length, they can truly reflect the behavior of users in the process of using the Internet. By classifying short texts, operators can more effectively analyze short texts generated in network services in order to discover user interests and Provide recommended services to users. Therefore, the problem of short text classification is a hot issue at present. Most of the short text classific...
