Gómez-Núñez AJ, Vargas-Quesada B, de Moya-Anegón F et al. Improving SCImago Journal & Country Rank (SJR) subject classification through reference analysis. Scientometrics 2011;89:741-758
This work introduces a proposal to improve the categorization of Scopus database journals included at the SCImago Journal & Country Rank (SJR) portal using reference analyisis of citing journals. This method represents a consistent and congruent new disciplinary structure, showing a solid performance in grouping journals at a higher level than categories - that is, aggregating journals into subject areas. It should be supplemented with additional techniques.
