The document presents a new algorithm called PAC (Page Access Coefficient) to calculate the rank of web pages for information filtering in social networks. The PAC algorithm aims to reduce computational calculations and time complexity compared to existing PageRank and Weighted PageRank algorithms. The PAC value for a web page is calculated based on the number of incoming links to the page, outgoing links from the page, and total number of pages. This value is used to rank pages when retrieving information, with the goal of presenting users the most relevant results first using less computations than other algorithms.
