Google’s Page Rank as a Citation Index

Google unearths physics gems. ‘Google could be a good way of measuring the “impact” of a particular scientific paper and might even be used to replace traditional citation indices, according to a new statistical analysis by physicists in the US. The researchers have found that the Google PageRank algorithm, which measures the relative importance of Web pages, can provide a systematic way to find important papers. The technique also uncovers scientific “gems” – top papers overlooked by conventional searches.’

Finding Scientific Gems with Google, P. Chen, H. Xie, S. Maslov, S. Redner, arXiv:physics/0604130v1 [physics.data-an]. Abstract: We apply the Google PageRank algorithm to assess the relative importance of all publications in the Physical Review family of journals from 1893–2003. While the Google number and the number of citations for each publication are positively correlated, outliers from this linear relation identify some exceptional papers or “gems” that are universally familiar to physicists.
