Embodiment Construction

[0055] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0056] Information extraction based on microblog classification is convenient for users to internally filter classified data. An information extraction method based on microblog classification in the present invention is divided into four stages.

[0057] In the first stage, through research, the labels required for each category are obtained.

[0058] In the second stage, various dictionaries are organized according to the target tags. Different categories and target tags require different dictionaries.

[0059] In the third stage, label extraction is performed on the blog post loop according to the classification and the target label.

[0060] In the fourth stage, the extracted tags are filtered and disambiguated. According to the classification and target tags, the final tag selection methods are different. See the...

Abstract

The invention relates to an information extraction method based on classification of microblogs. The method comprises the steps of (1) obtaining classification labels, (2) clearing up target labels, (3) carrying out label extraction by circulating a blog article according to the classification and the target labels and (4) carrying out filtration and disambiguation on extracted labels. The information extraction method based on classification of the microblogs is used for extracting secondary filtered labels in classified microblogs, all the labels can be found rapidly and comprehensively, filtration and screening are carried out, and accurate target labels are obtained.
