Which are the best performing regions in information science in terms of highly cited papers? Some improvements of our previous mapping approaches

Bornmann and Leydesdorff (2011) proposed methods based on Web of Science data to identify field-specific excellence in cities where highly cited papers were published more frequently than can be expected. Top performers in output are cities in which authors are located who publish a number of highly cited papers that is statistically significantly higher than can be expected for these cities. Using papers published between 1989 and 2009 in information science improvements to the methods of Bornmann and Leydesdorff (2011) are presented and an alternative mapping approach based on the Integrated Impact Indicator (I3) is introduced here. The I3 indicator was developed by Leydesdorff and Bornmann (2011b).
