PageRank Algorithm
Save
PageRank is a link analysis algorithm that assigns a numerical weight to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of "measuring" its relative importance within the set.
How PageRank Works
PageRank is calculated by iteratively passing a hypothetical "random surfer" through a network of documents or web pages. The random surfer starts on a random page and then randomly clicks on a link to another page. The probability of the surfer clicking on a particular link is proportional to the number of links from the current page to the other page. The surfer continues to click on links randomly until it reaches a "sink" page, which is a page with no outgoing links. The PageRank of a page is the probability that the random surfer will land on that page.
Applications of PageRank
PageRank is used by search engines to rank web pages in their search results. The higher the PageRank of a page, the more likely it is to appear near the top of the search results. PageRank can also be used to identify influential pages within a network, to track the spread of information through a network, and to recommend pages to users.
Benefits of Learning PageRank
