Data provided by Thomson Reuters from its Essential Science Indicators, January 1999-June 2009

The data above were extracted from the Essential Science Indicators database of Thomson Reuters. This database, currently covering the period January 1999 to June 2009, surveys only journal articles (original research reports and review articles) indexed by Thomson Reuters. Articles are assigned to a category based on the journals in which they were published and the Thomson Reuters journal-to-category field-definition scheme. Both articles tabulated and citation counts to those articles are for the period indicated. Here, our ranking is by citations per paper among nations that collected 5,000 or more citations during the period to reveal weighted impact. For articles with multiple authors from different nations, each nation receives full, not fractional, citation credit. Essential Science Indicators lists nations ranked in the top 50 per cent for a field over a given period, based on total citations. In computer sciences, 79 nations are listed, meaning 158 were surveyed. Twenty-seven nations collected at least 5,000 citations in this field during the period covered.

只知道带颜色的两个是师徒关系，不知道还有其他什么故事那？
