维基百科对HITS算法的定义:
Hyperlink-Induced Topic Search (HITS) (also known as Hubs and authorities) is a link analysis algorithm that rates Web pages, developed by Jon Kleinberg. It determines two values for a page: its authority(权威值、权威度), which estimates the value of the content of the page, and its hub(中心值、中心度) value, which estimates the value of its links to other pages.
