数据描述
The SCImago Institutions Rankings (SIR) is a classification of academic and research-related institutions ranked by a composite indicator that combines three different sets of indicators based on research performance, innovation outputs and societal impact measured by their web visibility.
The aim of SIR is to provide a useful metric tool for institutions, policymakers and research managers for the analysis, evaluation and improvement of their activities, outputs and outcomes.
>💬Also have a look at 💡 [ COUNTRIES Research & Science Dataset - SCImagoJR ] (https://www.kaggle.com/datasets/alijalali4ai/scimago-country-info-and-rank) 💡 [ Scientific JOURNALS Indicators & Info - SCImagoJR ] (https://www.kaggle.com/datasets/alijalali4ai/scimagojr-scientific-journals-dataset)
For the ranking purposes, the calculation is generated each year from the results obtained over a period of five year ending two years before the edition of the ranking. For instance, if the selected year of publication is 2024, the results used are those from the five year period 2018-2022. The only exception is the case of web indicators which have been calculated once the last year.
>☢️❓The entire dataset is obtained from public and open-access data of ScimagoIR ( SCImago Institutions Rankings) ScimagoIR ScimagoIR Ranking Methodology
- Document types: all documents types in SCOPUS are considered except Retracted, Erratum and Preprint.
- Multiple affiliations: in Higher Education sector we use fractional counting to calculate research indicators when authors have more than one institutional affiliation. In these cases we distribute the weight of a document among the institutions of the authors who present multiple affiliations.
- Multinational institutions (MUL) which cannot be attributed to any country have also been included.
- The institutions marked with an asterisk consist of a group of sub-institutions, identified by with the abbreviated name of the parent institution. The parent institutions show the results of all of their sub-institutions.
- The inclusion criterions are:
- The institutions had published at least 100 works included in the SCOPUS database during the last year of the selected time period.
- Citable documents (Article, Chapter, Conference Paper, Review and Short Survey) must represent at least 75% of total documents published by the institution.
- The SIR includes both, size-dependent and size-independent indicators; that is indicators influenced and not influenced by the size of the institutions. The source of information used for the indicators for innovation is PATSTAT database. The sources of information used for the indicators for web visibility are Google and Semrush. Unpaywall database is used to identify Open Access documents. Altmetrics from PlumX metrics and Mendeley are used for Societal Factor. The Overton database is used to identify documents cited in policy documents.
Indicators are divided into three groups:
1. Research (50%)
| Indicator | Weight | Description |
|---|---|---|
| Normalized Impact (NI) | 13 % | The values (in decimal numbers) show the relationship between an institution's average scientific impact and the world average set to a score of 1 - Size-independent |
| Excellence with Leadership (EwL) | 8% | amount of documents in Excellence in which the institution is the main contributor - Size-dependent |
| Output (O) | 8% | total number of documents published in scholarly journals indexed in Scopus- Size-dependent |
| Scientific Leadership (L) | 5% | amount of an institution’s output as main contributor, that is, the amount of papers in which the corresponding author belongs to the institution- Size-dependent |
| Not Own Journals (NotOJ) | 3% | number of documents not published in own journals (published by the institution) - Size-dependent |
| Own Journals (OJ) | 3% | number of journals published by the institution (publishing services) - Size-dependent |
| Excellence (Exc) | 2% | amount of an institution’s scientific output that is included in the top 10% of the most cited papers in their respective scientific fields - Size-dependent |
| High Quality Publications (Q1) | 2% | 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) indicator - Size-dependent |
| International Collaboration (IC) | 2% | Institution's output produced in collaboration with foreign institutions. computed by institution's output whose affiliations include more than one country address - Size-dependent |
| Open Access (OA) | 2% | percentage of documents published in Open Access journals or indexed in Unpaywall database - Size-independent |
| Scientific Talent Pool (STP) | 2% | number of different authors from an institution in the total publication output of that institution during a particular period of time - Size-dependent |
2. Innovation (30%)
| Indicator | Weight | Description |
|---|---|---|
| Innovative Knowledge (IK) | 10% | scientific publication output from an institution cited in patents. Based on PATSTAT - Size-dependent |
| Patents (PT) | 10% | percentage of the scientific publication output cited in patents - Size-dependent |
| Technological Impact (TI) | 10% | number of patent applications (simple families). Based on PATSTAT - Size-independent |
3. Societal (20%)
| Indicator | Weight | Description |
|---|---|---|
| (AM) | 3% | PlumX Metrics (weigth: 70%): number of documents that have at least one mention in PlumX Metrics (https://plumanalytics.com). We consider mentions in Twitter, Facebook, blogs, news and comments (Reddit, Slideshare, Vimeo or YouTube) Mendeley (weigth: 30%): number of documents that have at least one reader in Mendeley (https://www.mendeley.com). - Size-dependent |
