Abstract

The invention discloses a webpage text content extracting method and device. The method comprises the following steps of: acquiring two webpages which belong to a catalogue at the same hierarchy below the same site; for each acquired webpage, respectively executing the following steps of: dividing the webpage into content blocks; determining label density and / or link density of each content block; selecting the content block the label density and / or link density of which meets corresponding preset conditions; extracting the content block with the text content of being not consistent with the text contexts of the content blocks selected from another webpage; and determining the extracted content block as the text content of the webpage. By adopting the technical scheme of the invention, the problem that accuracy is lower when the text content of the webpage is extracted in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of Internet information processing, in particular to a method and device for extracting webpage text content. Background technique [0002] With the rapid development of Internet technology, the information on the webpage is becoming more and more abundant. In order to better use the information on the webpage, people are constantly pursuing technologies that can effectively organize and utilize online information. However, the webpage is not as neat as the traditional text , clean, which contains a lot of noise content, such as scripts added to enhance user interaction, navigation links added to facilitate user browsing, and advertising links added for commercial considerations, etc. The above noise content not only affects The efficiency of webpage information retrieval also leads to low retrieval accuracy. The accurate extraction of webpage content can not only filter the interference of navigation inform...
