There are international rankings that do not require self-reported data provided by institutions and are based on data derived only from the Internet, e.g. information from websites or bibliometric data from well-known sources such as the Web of Science databases, Scopus, or Google Scholar. These include University Ranking by Academic Performance (URAP), CWTS Leiden Ranking, the Center for World University Rankings (CWUR), or the Ranking Web of Universities (Webometrics), etc.
University Ranking by Academic Performance (URAP)
URAP ranking is based on six academic performance indicators that measure research quality, quantity, impact, and productivity and international scientific collaboration: Article (21%), Citation (21%), Total Document (10%), Article Impact Total (18%), Citation Impact (15%), International Collaboration (15%). The ranking is published by the Informatics Institute at Middle East Technical University in Ankara. In the 2022/2023 edition, 3000 HEIs have been ranked, including 55 Polish universities. Lodz University of Technology was classified at the 18th place in Poland, and 1051st place in the world.
TUL was also classified in the field-based URAP rankings: Chemical Sciences (541st place), Electrical & Electronics Engineering (700th place), Engineering (606th place), Mathematical Sciences (700th place), Physical Sciences (775th place), Technology (678th place), Materials Engineering (464th place), Biological Sciences (1066th place), Chemical Engineering (495th place), Energy & Fuels (490th place), Food Engineering (411th place), Mechanical Engineering (509th place), Medical and Health Sciences (1748th place), Molecular Biology & Genetics (692nd place), Polymer Science (199th place).
CWTS Leiden Ranking
The Leiden Ranking stands for a multidimensional perspective on university performance and presents a variety of indicators to explore the performance of universities from different angles. It provides indicators of scientific impact, collaboration, open access publishing, and gender diversity. It is up to users to select the indicator that they wish to use to rank universities. Compared with other university rankings, the CWTS Leiden Ranking offers more advanced bibliometric indicators. In its most recent edition 1318 universities were ranked, including Lodz University of Technology and 31 other Polish universities.
The Center for World University Rankings (CWUR)
The Center for World University Rankings (CWUR) is a leading consulting organization providing policy advice, strategic insights, and consulting services to governments and universities to improve educational and research outcomes. The ranking was published in 2012 for the first time. In its last edition TOP 2000 universities in the world have been classified including 40 HEIs from Poland. Lodz University of Technology was classified at 1374th place.
CWUR methodology uses 7 indicators grouped in 4 areas: quality of education (25%), alumni employment (25%), quality of faculty (10%) and research performance (40%).
Ranking Web of Universities (Webometrics)
It was established in 2004. It is the world's largest ranking, with all universities, not just the best ones, classified in it. It takes into account the presence and recognition of universities in the web. The aim is to promote open access to information (including scientific publications) and to encourage universities and researchers to ensure that their online presence reflects what they actually do. In the most recent edition TUL has been ranked 13th in Poland and 994th in the world (comparing to 26th and 1769th in the previous edition).
The ranking methodology considers three indicators: visiblity/impact (number of external networks/subnets linking to the institution's webpages), transparency/openness (number of citations from university Top210 authors, excluding the first 20) and excellence (number of papers amongst the top 10% most cited).
The Webometrics Ranking of World Universities is an initiative of the Cybermetrics Lab, a research group belonging to the Consejo Superior de Investigaciones Científicas (CSIC), the largest public research body in Spain. It is attached to the Ministry of Education and its main objective is to promote scientific research.
The rankings 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 (50%), innovation outputs (30%) and societal impact measured by their web visibility (20%). In the 2022 edition, 4364 HEIs were ranked, including 70 universities from Poland. Lodz University of Technology was classified at 614th place in the world and at 22nd place in Poland. In 2021, by subject rankings were included in the SCImago ranking for the first time. TUL was classified in 14 of them.
