Abstract

The invention discloses a method and device for updating, discovering and counting webpage information, which belongs to the field of computer applications and solves the problem that traditional RSS subscription news cannot obtain new news sources and track and count news sources. Concrete steps are as follows: (1) grab the step of URL module to grab webpage link; (2) news link module judges whether webpage link is the step of news link, if then go to step (3), otherwise go to step (1 ); (3) the news source module determines whether the web page link is the step of the news source, if it is then proceeds to step (4), otherwise proceeds to step (1); (4) the statistical news information module obtains the update time of the web page, calculates Steps in the update cycle of the newsfeed. The invention can dynamically capture and analyze the obtained news sources.

Description

technical field [0001] A method and device for discovering and counting webpage information updates, used for dynamically grabbing and analyzing obtained news sources, belonging to the field of computer applications. Background technique [0002] A web crawler is a program that automatically extracts web pages. It downloads web pages from the World Wide Web for search engines and is an important component of search engines. Traditional crawlers start from the URL of one or several initial webpages, obtain the URLs on the initial webpage, and continuously extract new URLs from the current page and put them into the queue during the process of crawling webpages until a certain stop condition of the system is met. The work flow of the focused crawler is relatively complicated. It needs to filter links that have nothing to do with the topic according to a certain webpage analysis algorithm, keep useful links and put them into the URL queue waiting to be crawled. Then, it will s...
