The SCImago Institutions Rankings (SIR) is a classification of academic and research-related institutions ranked by a composite indicator that combines three different groups of indicators based on research performance, innovation output and societal impact measured by their web visibility. In each group the following indicators are included:
Normalized Impact (Leadership Output) (13%) - Normalized Impact is computed over the institution's leadership output using the methodology established by the Karolinska Institutet in Sweden where it is named "Item oriented field normalized citation score average". The normalization of the citation values is done on an individual article level.
Excellence with Leadership (8%) - Excellence with Leadership indicates the amount of documents in Excellence in which the institution is the main contributor.
Output (8%) - Total number of documents published in scholarly journals indexed in Scopus.
Scientific Leadership (5%) - Leadership indicates the amount of an institution’s output as main contributor, that is, the amount of papers in which the corresponding author belongs to the institution.
Not Own Journals Output (3%) - Number of documents not published in own journals (published by the institution).
Own Journals (3%) - Number of journals published by the institution (publishing services).
Excellence (2%) - Excellence indicates the amount of an institution’s scientific output that is included in the top 10% of the most cited papers in their respective scientific fields.
High Quality Publications (2%) - The number of publications that an institution publishes in the most influential scholarly journals of the world. These are those ranked in the first quartile (25%) in their categories as ordered by SCImago Journal Rank (SJRII) indicato.
International Collaboration (2%) - Institution's output produced in collaboration with foreign institutions. The values are computed by analyzing an institution's output whose affiliations include more than one country address.
Open Access (2%) - Percentage of documents published in Open Access journals or indexed in Unpaywall database.
Scientific Talent Pool (2%) - Total number of different authors from an institution in the total publication output of that institution during a particular period of time.
Innovative Knowledge (10%) - Scientific publication output from an institution cited in patents. Based on PATSTAT (http://www.epo.org)
Patents (10%) - Number of patent applications (simple families). Based on PATSTAT (http://www.epo.org).
Technological Impact (10%) - Percentage of the scientific publication output cited in patents. Based on PATSTAT (http://www.epo.org)
SOCIETAL IMPACT (20%)
Altmetrics (10%) - Altmetrics indicator has been calculated over the 10% documents of the institutions (best documents regarding the normalized impact value). This indicator has two components:
Number of Backlinks (5%) - Number of networks(subnets) from which inbound links to the institution website came from. Data extracted from ahrefs database (https://ahrefs.com).
Web size (5%) - Number of pages associated to the institution’s URL according to Google (https://www.google.com)
