Research on the Internet

The ranking consists of a list of repositories which mainly house research projects, classified according to an indicator composed by a combination of data on internet impact and presence, obtained through the main search engines. It takes into account the number of page results offered by Google and the archives of specific downloaded formats, the quality of external links and articles published in recent years.

The Cybermetrics Lab, located at the Human and Social Sciences Centre of the Spanish National Research Council (CSIC), is dedicated to the quantitative analysis of internet contents, especially those related to scientific knowledge. It designs cybermetric indicators and techniques with the aim of studying the presence of research on the internet.
