Disciplinary Categories in Scopus
Scopus Categories used in VQR 2011-2014
The journals categorized in Scopus are accessible entering the platform Scimago Journal Ranking, where it is possible to select both general classes and subclasses.
The portal has the same name as the correspondent bibliometric indicator and allows to check all journals indexed in Scopus, pinpointing the disciplinary categories they belong to, as well as the correlated indicators and the quartiles.
The quartile of a journal is calculated taking into account the journal's ranking in its disciplinary category (Category Ranking). It is considered as a position indicator, the position given by the values of the indicators themselves, i.e. IF for WoS and SJR for Scopus.
If the same journal is indexed in more than one disciplinary category, different quartiles may be assigned.
The parameters for the classification in the two databases are not completely converging. For instance, it is possible that a journal is not indexed in one of them or that the degree assigned is different between the two, changing the number and the typology of the disciplinary categories assigned.
