Abstract

The invention provides a method and a device for mining key pages of a website. The method includes: extracting a navigation link list from each page of the website, splitting each extracted navigation link list into link pairs, wherein each link pair is composed of two links at adjacent positions in the navigation link list; determining key link pairs from all the link pairs, and taking the pages corresponding to the key link pairs as the key pages in the website. By the means, recall rate and accuracy rate when the key pages of the website are mined can be increased.

Description

【Technical field】 [0001] The invention relates to data mining processing technology, in particular to a method and device for mining key pages of a website. 【Background technique】 [0002] Web page authority is an important reference factor for search engines to rank results. When calculating the authority of a webpage, all the webpages participating in the calculation are regarded as a set, and the authority of the webpage is iteratively calculated through the link relationship between the webpages in the set. However, with the development of the Internet, there are more and more webpages on the Internet. If all webpages on the Internet are used as webpages participating in authoritative calculations, the requirements for the architecture of the computing system are very high, so usually only the websites and external websites are selected. Web pages with links are used as web pages participating in the authoritative calculation, but this method of the existing technology ...
