The Webometrics Ranking of World Universities, also known as Ranking Web of Universities, is a ranking system for the world’s universities based on a composite indicator that takes into account both the volume of the Web content (number of web pages and files) and the visibility and impact of these web publications according to the number of external inlinks (site citations) they received. The ranking is published by the Cybermetrics Lab, a research group of the Spanish National Research Council (CSIC) located in Madrid.
The aim of the Ranking is to improve the presence of the academic and research institutions on the Web and to promote the open access publication of scientific results. The ranking started in 2004 and is updated every January and July. As of 2021 it provides Web indicators for more than 31,000 universities worldwide.
In Webometrics 2021 country ranking, Institut Teknologi Sepuluh Nopember (ITS) has been listed in number 3. ITS ranking increased from the 6th position to the 3rd position in the country level. The world ranking increased significantly from 1840 to 1089. The Webometrics Ranking is published twice a year. The announcement is made in January and July. Webometrics uses both webometric and bibliometric indicators because it aims to rank universities, not the website of universities.
The current methodology used three indicators to evaluate the university performance, i.e., visibility, transparency (openness), and excellence. The indicator of presence has been discontinued. Visibility, transparency, and excellence are weighted 50%, 10%, and 40% respectively. The visibility indicator represents the number of external networks (subnets) linking to the institution’s webpages (normalized and then the maximum value is chosen). Transparency (openness) is evaluated through the number of citations from the Top 210 authors (excl. top 20 outliers). The third indicator, excellence, represents the number of papers amongst the top 10% most cited in each one of the all 27 disciplines of the full database, using a five-year period.
