Link Analysis plays an important role in Web Information Retrieval. Most of the existing link analysis algorithms use link as the main factor to determine the importance of a Web page, which can not reflect complicated relationships among Web pages. In this paper, we propose G-HITS (Gravitation-Based HITS), which condenses useful information associate to a Web as its "mass ", and reflects relationship between two Web pages as "attractive force" inspired by Newton's theory of gravitation, thus giving a physical interpretation for link analysis. Experimental results show that G-HITS is more reasonable to interpret link analysis problems and it can identify higher quality authorities on given topics.
