A methodology for Institution-Field ranking based on a bidimensional analysis: The IFQ2A-index Torres Salinas, Daniel García-Moreno, José Delgado López-Cózar, Emilio Herrera Triguero, Francisco Rankings Universities Higher Education Bibliometrics Shanghai ranking Bidimensional analysis Evaluation models Research performance assessment H index The problem of comparing academic institutions in terms of their research production is nowadays a priority issue. This paper proposes a relative bidimensional index that takes into account both the net production and the quality of it, as an attempt to provide a comprehensive and objective way to compare the research output of di erent institutions in a specfic field, using journal contributions and citations. The proposed index is then applied, as a case study, to rank the top Spanish universities in the felds of Chemistry and Computer Science in the period ranging from 2000 until 2009. A comparison with the top 50 universities in the ARWU rankings is also made, showing the proposed ranking is better suited to distinguish among non-elite universities 2011-11-28T07:44:40Z 2011-11-28T07:44:40Z 2011 info:eu-repo/semantics/article 0138-9130 1588-2861 http://hdl.handle.net/10481/18681 eng http://creativecommons.org/licenses/by-nc-nd/3.0/ info:eu-repo/semantics/openAccess Creative Commons Attribution-NonCommercial-NoDerivs 3.0 License Scientometrics
