All new: January 2017 Edition

        The annual 2017 edition is compiled with data from about 8 000 research centers worldwide collected during January 2017. To calculate the composite index (World Ranking) we have combined normalized values, the ranks are showed for informative purposes. The indicators used and their weighting are described below. Due to our limited resources we decided to update the Ranking Web (Webometrics) of Research Centers only one time a year (in late January).
