Mapping OECD’s Revised Field of Science and Technology (FOS) Classification to Scopus' All Science Journal Classification Codes (ASJC)

The OECD Category schema corresponds to the Revised Field of Science and Technology (FOS) Classification of the Frascati Manual. It consists of 40 subcategories of 6 major fields, namely Natural Sciences, Engineering and Technology, Medical and Health Sciences, Agricultural Sciences, Social Sciences and Humanities. The All Science Journal Classification (ASJC) system in Scopus categorizes journals and articles into subject areas to facilitate research and discovery. The ASJC includes a broad range of disciplines, divided into four main areas: Life Sciences, Physical Sciences, Health Sciences, Social Sciences and Humanities. These subject areas are further divided into more specific sub-categories to provide detailed classification for scholarly content. Mapping process was conducted in January 2023, utilizing the then-current versions of the classifications.
