Thomson Scientific in the United States, which provides information of academic documents, announced the world ranking of the highest number of theses cited by each research institution. Tokyo University and Tohoku University placed 1st in Physics and Materials Science, respectively, for 3 years in a row, from 2002 to 2004. Max Planck, which strategically combined 80 research institutions in order to place at the top, was given 1st place in 2005 and 2006. Yet, it may be considered that Tokyo University and Tohoku University have been the leading schools for research for 5 years in a row.
In April 2004, Thomson Scientific Co. in the United States announced the world rankings of research institutions by judging the number of theses which they cited. For three years in a row, first place was awarded to Tokyo University for Physics and Tohoku University for Materials Science. Theses published in the 11-year period from 1993 to 2003 were considered. Kyoto University for Chemistry was in second place, while Tokyo University for Biology and Biochemistry took fifth place. For the 10-year period, twenty-four institutions in Japan ranked in the top 1%.
Many research institutions made use of this ranking in their organizational strategy. Max Planck institutions in Germany amalgamated institutions of their subsidiaries under the name of “Max Planck Society”. As a result, these institutions ranked in the top 1% in the world, in 21 out of 22 fields of “Essential Science Indicators”. Regarding these results, Thomson Scientific Co. comments every year: In three fields, Chemistry, Materials Science and Physics, Max Planck institutions have been ranked No.1 since 2005. However, this is a result of Max Planck Society having united all the names of more than 80 research institutions which belong to that Society. Tohoku University for Materials Science and Tokyo University for Physics should not be ranked any lower, given that they have consistently been in first place (until 2004).
Materials Science academic papers of Tohoku University and Physics papers from Tokyo University were virtually number one in the world, although the schools’ performances were ranked second in the world in 2005 and 2006. They were unbeaten until Max Planck Society was created.
In 2005 Kyoto University for Chemistry came in 3rd place, while Tokyo University for Biology and Biochemistry was in fifth place. In 2006 Kyoto University for Chemistry was in 3rd place. Overall, the number of citations tends to increase with the number of theses, and academic dispatching to the world from top Japanese research institutions is becoming more active.
