PageRank

Authority measurement as graph-centrality computation, introduced by Page, Brin, Motwani, and Winograd (1998). A page’s authority is a function of the authorities of the pages that link to it, computed iteratively across the web’s link graph. The foundational model on which modern web search infrastructure was built. Difference from AVO: calibrated for the link-and-list discovery surface; does not measure the conditions that determine citation in synthesised AI answers.
