Abstract

The invention discloses a webpage screening method and a webpage screening device. The method comprises that preset seed webpage is captured; uniform resource locator (URL) information included by the seed webpage is captured; webpage mass fraction corresponding to the URL information is calculated; the URL information is divided into corresponding candidate gather according to preset network address information; the URL information which is not greater than the preset pressure quota is screened out from each candidate gather, the URL information which is screened out and corresponding to the webpage mass fraction which is not lower than the webpage mass fraction and corresponding to arbitrary residual URL information in the relative candidate gather is screened out. The captured pressure value corresponding to the network address is ensured based on the preset pressure quota. The webpage corresponding to the URL information which is screened out is regarded as the target captured webpage. The method lowers the risk of the capturing webpage failure or the risk of banning site so that the goal of improving the success rate of capturing the webpage is achieved.

Description

technical field [0001] The invention relates to the technical field of information retrieval, in particular to a webpage screening method and device suitable for a web crawler system. Background technique [0002] A web crawler, an important component of a search engine, is a program that automatically extracts web pages, and it downloads web pages from the Internet for search engines. In order to meet the needs of search engines to quickly and comprehensively cover valuable information on the Internet, crawlers need to crawl a large number of web pages every day. [0003] Because there is a large amount of webpage information in the Internet, and the crawling ability of the web crawler is limited, therefore, in order to screen out webpages with higher webpage quality, the existing webpage screening method comprises: after the web crawler grabs one or several seed webpages, Extract the URL information on the seed webpage, calculate the webpage quality score corresponding to...
