College and university rankings in the context of "Ondokuz Mayıs University"

The QS World University Rankings is a portfolio of comparative college and university rankings compiled by Quacquarelli Symonds, a higher education analytics firm. Its first and earliest edition was published in collaboration with Times Higher Education (THE) magazine as Times Higher Education–QS World University Rankings, inaugurated in 2004 to provide an independent source of comparative data about university performance. In 2009, the two organizations parted ways to produce independent university rankings, the QS World University Rankings and THE World University Rankings.

QS's rankings portfolio has since been expanded to consist of the QS World University Rankings, the QS World University Rankings by Subject, four regional rankings tables (including Asia, Latin America and the Caribbean, Europe, and the Arab Region), several MBA rankings, and the QS Best Student Cities rankings. In 2022, QS launched the QS World University Rankings: Sustainability, and in 2023, it launched the QS World University Rankings: Europe. The rankings are intended to reflect and articulate university performance for the next academic year. Therefore, they are usually named for the year following that in which they are produced. The rankings are regarded as one of the most-widely read university rankings in the world, along with Academic Ranking of World Universities and Times Higher Education World University Rankings. According to Alexa Internet, it is the most widely viewed university ranking worldwide in 2020.

The Academic Ranking of World Universities (ARWU), also known as the Shanghai Ranking, is one of the annual publications of world university rankings. The league table was originally compiled and issued by Shanghai Jiao Tong University in 2003, making it the first global university ranking with multifarious indicators.

Since 2009, ARWU has been published and copyrighted annually by Shanghai Ranking Consultancy, an organization focusing on higher education that is not legally subordinated to any universities or government agencies. In 2011, a board of international advisory consisting of scholars and policy researchers was established to provide suggestions. The publication currently includes global league tables for institutions as a whole and for a selection of individual subjects, alongside independent regional Greater China Ranking and Macedonian HEIs Ranking.

Citation impact or citation rate is a measure of how many times an academic journal article or book or author is cited by other articles, books or authors.Citation counts are interpreted as measures of the impact or influence of academic work and have given rise to the field of bibliometrics or scientometrics, specializing in the study of patterns of academic impact through citation analysis. The importance of journals can be measured by the average citation rate,the ratio of number of citations to number articles published within a given time period and in a given index, such as the journal impact factor or the citescore. It is used by academic institutions in decisions about academic tenure, promotion and hiring, and hence also used by authors in deciding which journal to publish in. Citation-like measures are also used in other fields that do ranking, such as Google's PageRank algorithm, software metrics, college and university rankings, and business performance indicators.
