9. Research - Ⅱ. Comparisons of Publication Quantity and Quality

Note

  1. FWCI（Field-Weighted Citation Impact) is the number of citations received by the publication, divided by the world average for the same type of publications in the same field and same publication year. An FWCI of 1 or higher indicates that the publication's impact exceeds or equals the world average.
  2. Types of publications included: articles and reviews. Self-citations: included.
  3. RU11 (Research University 11) is a consortium that aims to develop academia via eleven universities: Hokkaido University, Tohoku University, University of Tsukuba, The University of Tokyo, Waseda University, Keio University, Tokyo Institute of Technology, Nagoya University, Kyoto University, Osaka University, and Kyushu University. RU11 is composed of both national and private universities.
  4. The number and percentage of publications carried in journals in top percentiles, based on citation counts. It indicates the number of publications in the top 1%, 5%, 10% or 25% of journals based on the number and percentage of citations in Elsevier’s Scopus each year.
  5. Types of publications included: articles and reviews. Top journals by CiteScore percentile.
  6. Percentage of Outputs in Top 10% Citation Percentiles: This metric represents the percentage of publications that fall within the top 10% of annual citation counts in Elsevier's Scopus database, based on citation performance within their respective fields and publication years. 
  7. Types of publications included: articles and reviews. Self-citations: included. Field-weighted: yes.
  8. The 27 subject areas and 334 fields is based on the Scopus ASJC categorization (ASJC: All Science Journal Classification). Translation assistance: NIAD-QE, the National Institution for Academic Degrees and Quality Enhancement of Higher Education (the major field categories are Elsevier translations).
  9. A higher number of publications combined with a higher FWCI indicates robust research capacity (a university's strength). Conversely, a smaller number of publications with a high FWCI often reflects the presence of highly productive individual faculty members. Notably, when individual researchers are affiliated with large research communities, both publication volume and FWCI metrics tend to rise significantly.
  10. Multidisciplinary field is one in which publications are carried in general scientific magazines such as Nature and Science.
  11. In 157 out of 318 fields, the FWCI exceeds the global average of 1.0. Fields with a high FWCI but low publication volume may indicate the presence of highly productive individual faculty members. Conversely, fields with both a high FWCI and substantial publication output demonstrate robust research capacity—a key institutional strength.
  12. ASJC field "Engineering (miscellaneous)" refers to topics besides the following: Aerospace Engineering; Automotive Engineering; Biomedical Engineering; Civil and Structural Engineering; Computational Mechanics; Control and Systems Engineering; Electrical and Electronic Engineering; Industrial and Manufacturing Engineering; Mechanical Engineering; Mechanics of Materials; Ocean Engineering; Safety, Risk, Reliability, and Quality; Media Technology; Building and Construction; Architecture.
