U.S. News Global Universities Subject Ranking

U.S. News ranks the top Universities in 22 scientific fields, using different criteria and variable weights in each field. These criteria are:

• Global research reputation: This indicator reflects the aggregation of the most recent five years of results of the Academic Reputation Survey for the best universities globally for research.

• Regional research reputation: This indicator reflects the aggregation of the most recent five years of results of the Academic Reputation Survey for the best universities for research in the region; regions were determined based on the United Nations definition.

• Publications: This is a measure of the overall research productivity of a university, based on the total number of scholarly papers – reviews, articles and notes – that contain affiliations to a university and are published in high-quality, impactful journals. This indicator is closely linked to the size of the university. It is also influenced by the discipline focus of the university, since some disciplines, particularly medicine, publish more than others.

• Normalized citation impact: The total number of citations per paper represents the overall impact of the research of the university and is independent of the size or age of the university; the value is normalized to overcome differences in research area, the publication year of the paper and publication type.

• Total citations: This indicator measures how influential the university has been on the global research community. Total citations have been normalized to overcome differences in research area, publication year of the paper and publication type.

• Number of publications that are among the 10 percent most cited: This indicator reflects the number of papers that have been assigned as being in the top 10 percent of the most highly cited papers in the world for their respective fields.

• Percentage of total publications that are among the 10 percent most cited: This indicator is the percentage of a university's total papers that are in the top 10 percent of the most highly cited papers in the world – per field and publication year. It is a measure of the amount of excellent research the university produces and is independent of the university's size.

• Number of highly cited papers that are among the most cited top 1% in their respective field

• Percentage of total publications that are among the most cited top 1%

• Percentage of total publications with international collaboration

• Percentage of total publications that are among the top 1 percent most highly cited papers: This percent of highly cited papers shows the number of highly cited papers for a university divided by the total number of documents it produces, represented as a percentage.

• Books: Books are an important medium of publication for scholarly research, particularly in the social sciences, arts and humanities.

• Conferences: Academic conferences are an important venue for scholarly communication, particularly in disciplines tied to engineering and computer science.

All data for the above criteria are derived from the Web of Science database and cover the last 5 years.
