Abstract

The invention discloses a method and a device for extracting webpage text content. The method includes steps of dividing a webpage with requirement on text content extraction into different content blocks; executing operations, including determining link text length and non-link text length of the content blocks, to the different divided content blocks respectively; determining the link text density of the corresponding content block according to the determined link text length and non-link text length; and determining that the content blocks are the text content of the webpage when the link text density is not higher than a first specified threshold value. By the method and the device for extracting webpage text content, the problem of low accuracy in webpage text content extraction in the prior art is solved.

Description

Technical field [0001] The present invention relates to the field of Internet information processing technology, and in particular to a method and device for extracting webpage body content. Background technique [0002] With the rapid development of Internet technology, the information on web pages is becoming more and more abundant.
