Scholar Metrics: el impacto de las revistas según Google, ¿un divertimento o un producto científico aceptable?
This paper reviews the most significant features of Google Scholar Metrics, pointing out their strengths and weaknesses, and discusses the possibilities of adoption for evaluating journals
Las revistas españolas de Ciencias Sociales y Jurídicas en Google Scholar Metrics ¿están todas las que son?
New paper of EC3 about Google Scholar Metrics. The coverage of Spanish relevant journals in Social Sciences and Law is assessed. We conclude that Google Scholar Metrics shouldn't be used to evaluate national journals in these areas because of its limitations
Google Scholar Metrics: una herramienta poco fiable para la evaluación de revistas científicas
We introduce Google Scholar Metrics (GSM), a new bibliometric product of Google that aims at providing the H-index for scientific journals and other information sources. We conduct a critical review of GSM showing its main characteristics and possibilities as a tool for scientific evaluation. We discuss its coverage along with the inclusion of repositories, bibliographic control, and its options for browsing and searching. We conclude that, despite Google Scholar’s value as a source for scien- tific assessment, GSM is an immature product with many shortcomings, and therefore we advise against its use for evalu- ation purposes. However, the improvement of these shortcomings would place GSM as a serious competitor to the other existing products for evaluating scientific journals.Se presenta Google Scholar Metrics (GSM), el nuevo producto bibliométrico de Google, que computa el índice h de revistas y otras fuentes de información científica. Se exponen las principales características de GSM, y se realiza una revisión crítica de sus posibilidades como herramienta para la evaluación de revistas científicas. Se estudia, entre otros aspectos, su cobertura, la inclusión de repositorios junto a las revistas científicas, el control bibliográfico de la información, y las posibilidades de consulta y visualización de resultados. Se concluye que, pese a las potencialidades de Google Scholar como fuente para la evaluación científica, GSM es un producto inmaduro y con múltiples limitaciones por lo que no se aconseja su uso con fines evaluativos. Igualmente se plantea que la mejora de sus prestaciones, posicionaría a GSM como una seria competencia para los productos de evaluación de revistas existentes en el mercado de la información científica
Tracking the performance of an R&D programme in the biomedical sciences
Pre-refereed version of manuscript accepted for publication in Research EvaluatioN: arXiv:1602.04049This article aims at offering an evaluation framework of an R&D programme in the biomedical sciences. It showcases the Spanish Biomedical Research Networking Centres (CIBER) initiative as an example of the effect of research policy management on performance. For this, it focuses on three specific aspects: its role on the national research output in the biomedical sciences, its effect on promoting translational research through internal collaboration between research groups, and the perception of researchers on the programme as defined by their inclusion of their CIBER centres in the address field. Research output derived from this programme represents around 25% of the country’s publications in the biomedical fields. After analysing a 7-year period, the programme has enhanced collaborations between its members, but they do not seem to be sufficiently strong. 54.5% of the publications mentioned this programme in their address; however, an increase in the share of papers mention is observed 2 years after it was launched. We suggest that by finding the point at which the share of mentions stabilizes may be a good strategy to identify the complete fulfilment of these types of R&D policies.This work was supported by the Spanish Fondo de Investigacion Sanitaria (FIS) [PI10/01122].Peer reviewe
Productividad e impacto de los investigadores españoles: umbrales de referencia por áreas científicas
Reference thresholds for the scientifi c production and impact of internationally
visible Spanish research within the areas defi ned by the Spanish National Agency for
Evaluation and Prospective (ANEP) are presented. These percentile reference tables
are constructed from the population of researchers who applied for a project within
Spain’s National R & D Plan 2007 (n = 3.356) and are to serve as benchmarks, permitting
comparisons between researchers’ bibliometric behavior and mean performance in
their respective scientifi c disciplines. Data relating to mean production, impact and
visibility for each ANEP area are also presented. The internationalization of these areas
between 2000 and 2006 is discussed, with special emphasis on the Social Sciences.
Finally, we suggest funding agencies and research institutions use these reference
thresholds as assessment tools in their selection processes.Se presentan umbrales de referencia de producción e impacto científi co de la
investigación española con visibilidad internacional para las áreas defi nidas por la
Agencia Nacional de Evaluación y Prospectiva (ANEP) en sus convocatorias. Tomando
como población los solicitantes de proyectos del Plan Nacional de I + D 2007 (n = 3.356)
se construyen tablas de referencia por percentiles que funcionan a modo de benchmarks,
permitiendo efectuar comparaciones entre el comportamiento bibliométrico de un
investigador y los registros de referencia en su área científi ca. Igualmente se ofrecen
los datos de producción, impacto y visibilidad promedios para las áreas ANEP, y se
discute el proceso de internacionalización de dichas áreas en el período 2000-2006
Altmetrics: not everything that can be counted, counts
En 2012 se multiplicaron las propuestas sobre nuevos indicadores asociados a aplicaciones de la web social, denominados altmetrics (o métricas alternativas) y se presentan como una alternativa a la evaluación de la actividad científica. Sin embargo, pese a las múltiples propuestas, dicho campo aún está en fase embrionaria. Se presentan algunas posibles limitaciones de los nuevos indicadores:
1) gran número de fuentes de información e indicadores que hacen difícil establecer su clasificación y relevancia; 2) muchos no tienen demasiada validez estadística por los pobres resultados que generan; 3) es difícil determinar cuál es el significado de las nuevas medidas ya que no sabemos si se mide exactamente impacto social o científico; y 4) carácter evanescente y efímero.In 2012 there were many proposals for new indicators associated with social web tools. These indicators have been termed as altmetrics (or alternative metrics) and are presented as an alternative to the evaluation of scientific activity. In this paper some possible limitations of the new indicators are presented. More specifically these shortcomings are: 1) a large number of information sources and indicators that make it difficult to establish their classification and relevance; 2) some indicators that have no statistical validity because they generate poor results; 3) the difficulty of determining the meaning of the new metrics –what are we assessing, scientific or social impact?; and 4) the evanescent and ephemeral nature of these new sources and indicators
Indicators for usage and participation in scientific journals 2.0: the case of PLoS One
The new publishing and scientific communication environments have led to the emergence of new Web indicators. Along with usage metrics such as downloads there are many measures that are generated from Science 2.0. Journals published by the Public Library of Science systematically collect many of these new metrics. The objective of this paper is to present some of these new indicators and analyze them quantitatively through the case study of 8945 papers published in the journal PLoS One. The selected indicators were; comments, ratings, number of bookmarks, links from scientific weblogs, downloads views and citations. Basic descriptive statistics indicators and correlations have been calculated for all of them. The results show the low participation of scientists in Web 2.0 and how most of these indicators, except for downloads and visits, are poorly consolidated metrics
Tools for evaluating science in universities and R&D centres: descriptions and usage
Indicators have become essential to Spanish universities. Some of the major funding calls for proposals (Campus of international excellence, Severo Ochoa centres of excellence, etc.) rely heavily on R&D indicators. We review some of the tools that universities have to generate indicators, apart from the traditional citation indexes: 1) scientific information systems, 2) bibliometric suites from commercial companies, and 3) university rankings. The use of these tools and the need for librarians to manage them are discussed
Google scholar citations and the emergence of new actors in research evaluation
Google scholar citations, a system aimed at researchers, attempts to outline researchers’ bibliometric profile, providing citation indicators and the h-index. We review other tools designed to measure visibility and academic impact on the web, such as Microsoft academic search and the new initiatives grouped under the label altmetrics or alternative indicators. Finally, we discuss how the appearance of Google scholar citations and other products may affect the two major sources of bibliometric data, ISI Web of science and Scopus, and how this can influence the evaluation of scientific research
