Abstract

The invention discloses a method, a device and a storage medium for extracting news webpage content, which relate to the technical field of news webpage content extraction. The method comprises the following steps: obtaining HTML code of the webpage, HTML linear reconstruction of the webpage, removing HTML noise label, filtering and dividing data set, absorbing pseudo noise paragraph, and generating text paragraph. HTML linear reconstruction of web page linearizes the tree-shaped div tags nested with each other, and the linear structure can be conveniently located as a div tag, thereby eliminating the influence of nested tags on subsequent steps; HTML noise label removal will reduce the impact of noise text on paragraph clustering; Data set filtering partitioning further reduces the effectof noise on text segments; Absorbing pseudo-noise paragraphs increases the recall rate of text paragraphs. The method overcomes the shortcomings of specific crawling of specific websites and enhancesthe generality of extracting news page content. Compared with the existing technology, the method can extract news content accurately and efficiently, and has a good effect.
