Embodiment Construction

[0036] There are three key points in the implementation of the present invention: blog text content feature extraction, blog page link feature extraction and blog text time distribution feature extraction. After obtaining the blog page data, the present invention obtains the feature vector through text content analysis, blog page link analysis and blog text time attribute analysis, and uses an automatic text classification algorithm to realize accurate classification of spam blogs.

[0037] 1. Feature extraction of blog text content:

[0038] As far as a single article is concerned, a blog article (including the article title) is used as the object, and the feature item is represented by the binary method. Binary representation, that is, one of {0, 1} is selected, and the keyword that appears is represented by 1, and the keyword that does not appear is represented by 0. In the standardized word frequency representation method, it is necessary to make appropriate improvements ...

Abstract

The invention discloses a method for detecting a garbage blog. The method is designed as follows: through analyzing a cheating technology of network garbage, the method aims at an essential attribute of the garbage blog, adopts a technology of text classification in binary classification and surrounds three angles of the content characteristic of a blog text, the link character of a blog page and the time distribution character of the blog text, The method is built on the basis of the comprehensive analysis of the content of a blog webpage and carries out optimization on the operation of character extraction of the blog, thereby ensuring the higher accuracy rate of classifying the garbage blog.

Description

technical field [0001] The invention relates to blogs and text classification technology, in particular to a method for detecting spam blogs. Background technique [0002] In recent years, the blog, a new thing, has developed vigorously, resulting in a large amount of blog information. However, as a by-product of blogs, spam blogs also emerge as the times require. Their existence greatly wastes network bandwidth and storage resources, increases the difficulty for people to obtain high-quality information, and also reduces network users' satisfaction with blog search experience. [0003] A normal blog has two characteristics: one is composed of short and frequently updated articles; the other is that the posted articles are arranged in reverse chronological order. In addition to the above characteristics, spam blogs also have the characteristics of link factories and advertising blogs. The link factory feature means that the spam blog pages pile up a large number of popular...
