概要	VOSviewer-assisted citation analysis combines established citation analysis methodology with the visual mapping capabilities of VOSviewer, a free bibliometric software developed at Leiden University. Researchers export bibliographic records from databases such as Web of Science or Scopus, import them into VOSviewer, and generate citation networks that reveal which documents, authors, or journals are most influential and how intellectual influence flows across a field.	Co-citation analysis is a method that identifies the intellectual structure of a research domain by examining how frequently pairs of documents are cited together in other publications. When two papers are frequently cited together in the literature, they are considered co-cited, indicating they are conceptually related or influential within the same research community. Developed by Henry Small in 1973, co-citation analysis maps the 'invisible colleges' of science—networks of researchers working on related problems—and reveals how knowledge domains evolve over time.
