  • A global map of science according to a topic model of EU grants

    Open AccessAdrià Plazas, Nicandro Bovenzi et al.ARTICLEQuantitative Science Studies2026

    Since their appearance in the 1980s, global maps of science have proved useful to locate the relative position of topics and organisations in large scientific landscapes, providing strategic information for portfolio analyses in science policy. At this global level (global meaning here 'all disciplines'), these maps have been based on publications and have mostly used citations to build the relationship between scientific fields. Here, we present…

  • Towards multiple ontologies in science mapping. A tribute to Loet Leydesdorff

    Open AccessIsmael RàfolsARTICLEScientometrics2025

    This article reviews Loet Leydesdorff’s contributions to science mapping. It explains how over the years, his mapping techniques evolved from journal mapping to global maps of science and finally towards interactive interfaces portraying multiple classifications and ontologies. It then critically reviews the challenges faced by current approaches to science mapping, which implicitly assume a ‘natural’ epistemic structure, with examples from two r…

  • Cross-disease spillover from research funding

    Open AccessJordan Coburn, Ohid Yaqub et al.ARTICLESocial Science & Medicine2024Citada por: 1Referências: 30

    There is widespread appreciation for the role of research in addressing health problems. However, there is limited evidence on the extent to which research can be targeted to specific diseases. Analyses highlighting a concentration of research funding towards certain diseases have prompted growing scrutiny over the allocation of research funding. In this paper, we show that research funding targeted to a disease often results in publications rela…

  • Latmétricas

    Open AccessGabriel Vélez Cuartas, Germana Fernandes Barata et al.ARTICLEQuantitative Science Studies2023

    This special issue presents a small selection of contributions from Latmétricas 2021, among those submitted by authors. This Conference brought together more than 500 practitioners and researchers from every corner of Latin America and the Caribbean. There were sessions on new metrics, measuring open access effects on productivity and impact, the relationship between gender and scientific assessment, STI policies and assessment in regional govern…

  • Medidas insuficientes para un cambio en la evalua-ción de la investigación en España

    Open AccessEmilio Delgado López‐Cózar, Ismael Ràfols et al.ARTICLERecerca2021

    En una carta publicada hace seis meses (Delgado-López-Cózar, et al., 2021), pocas semanas después de que la Agencia Española de Evaluación se adhiriera a la declaración dora (dora, 2012), hacíamos un llamamiento a las autoridades científicas españolas para que abandonaran las políticas de evaluación de la investigación basadas en un uso excesivo e indiscriminado de los indicadores bibliométricos —especialmente el Journal Impact Factor (jif)—, par…

  • Letter

    Open AccessEmilio Delgado López‐Cózar, Ismael Ràfols et al.ARTICLEEl Profesional de la Informacion2021

    This letter is a call to the Spanish scientific authorities to abandon current research evaluation policies, which are based on an excessive and indiscriminate use of bibliometric indicators for nearly all areas of scientific activity. This narrow evaluation focus is especially applied to assess the individual performance of researchers. To this end, we first describe the contexts in which the journal impact factor (JIF) and other bibliometric in…

  • Five ways to ensure that models serve society

    Open AccessAndrea Saltelli, Gabriele Bammer et al.ARTICLENature2020

  • Bridging the divide between qualitative and quantitative science studies

    Open AccessL Leydesdorff, Ismael Ràfols et al.ARTICLEQuantitative Science Studies2020

    In January 2019, the Editorial Board of the Journal of Informetrics decided to resign following a series of disagreements with Elsevier. In collaboration with the International Society for Scientometrics and Informetrics (ISSI) and MIT Press, the Editorial Board thereupon launched this journal: Quantitative Science Studies (QSS). The launch of QSS offers an opportunity to rethink the contents and research agenda of the journal, and marks a turn f…

  • Does Interdisciplinary Research Lead to Higher Citation Impact? The Different Effect of Proximal and Distal Interdisciplinarity

    Open AccessAlfredo Yegros, Alfredo Yegros-Yegros et al.ARTICLEPLoS ONE2015

    This article analyses the effect of degree of interdisciplinarity on the citation impact of individual publications for four different scientific fields. We operationalise interdisciplinarity as disciplinary diversity in the references of a publication, and rather than treating interdisciplinarity as a monodimensional property, we investigate the separate effect of different aspects of diversity on citation impact: i.e. variety, balance and dispa…

  • A global map of science based on the ISI subject categories

    Open AccessL Leydesdorff, Ismael RàfolsARTICLEJournal of the Association for…2009

    The decomposition of scientific literature into disciplinary and subdisciplinary structures is one of the core goals of scientometrics. How can we achieve a good decomposition? The ISI subject categories classify journals included in the Science Citation Index (SCI). The aggregated journal‐journal citation matrix contained in the Journal Citation Reports can be aggregated on the basis of these categories. This leads to an asymmetrical matrix (cit…

  • Strategies for Knowledge Acquisition in Bionanotechnology

    Ismael RàfolsARTICLEInnovation The European Journal…2007Citada por: 5Referências: 1

    Discourses on convergent technologies claim that fields such as bionanotechnology are interdisciplinary and, therefore, require specific organizational forms, such as laboratories with researchers from many different disciplinary backgrounds. However, empirical investigations challenge the intrinsic interdisciplinarity of these emergent fields, and some analysts criticize the discourses as prescriptive. In order to investigate actual laboratory p…
