Abstract

The present invention provides an aggregated text density based webpage body text extraction method and apparatus. In the method, webpage text content is segmented by a method of separating a webpage HTML according to a tag, so as to effectively separate various types of texts in the content. A special website extraction rule does not need to be customized, so that the method is high in generality; a complex text mining means is not required, so that the method is simple and efficient and accurate for extraction of various types of webpage body texts.

Description

technical field [0001] The present invention relates to the technical field of webpage reptiles, in particular to a method and device for extracting webpage text based on aggregated text density. Background technique [0002] With the rapid development of social informatization, the Internet has become an important source of information for people. Netizens usually use browsers to directly view the content of web pages. In addition, there are many Internet-based information processing tasks (such as information retrieval, data mining, machine translation, etc.) that are also based on the information content of web pages. The body of the web page is processed. But besides useful information (such as body content), most web pages also contain a lot of noise information, such as website navigation information, related links and advertisements, copyright information, and some scripting languages. How to extract the text information of web pages accurately and efficiently, so a...
