Abstract

The invention provides a webpage crawling cycle adjusting method and a device. The method comprises the steps of acquiring a link assembly included in a target webpage crawled by a web crawler currently and information pages pointed by links in the link assembly; determining new-generated links in the link assembly and belonging to the target webpage, and taking links, belonging to websites which are the same as a first website, in the new-generated links, as links to be analysed, wherein webpage addresses in crumb navigation of information pages pointed by the links to be analysed are the same as a first webpage addresses; and adjusting crawling cycles of target webpages according to the links to be analysed existing in the target webpages crawled at different crawling moments within an appointed time. The webpage crawling cycle adjusting method is capable of improving accuracy of the determined crawling cycle of a webpage and reducing resource waste.

Description

technical field [0001] The present application relates to the technical field of network information processing, and in particular, to a method and device for adjusting a webpage crawling period. Background technique [0002] A web crawler is a program that automatically extracts web pages and is an important part of search engines. The webpage information of the webpage is crawled by the web crawler, and the crawled webpage information is analyzed to determine whether a new link is generated in the webpage to determine whether a new content page (that is, the actual page pointed to by the link) is generated in the webpage. content), so that changes to web pages can be monitored. [0003] Under normal circumstances, the web crawler crawls the webpage information of the target webpage at fixed time intervals according to the crawling cycle of the target webpage, but if the crawling frequency of the target webpage is too low, it is likely to miss the target webpage. Correspo...
