Hacia las unidades de bibliometría en las universidades: modelo y funciones
Torres-Salinas, Daniel,Jiménez-Contreras, Evaristo
Revista Espa?ola de Documentación Científica , 2012,
Abstract: In recent years, bibliometric indicators have been firmly established as a tool for research management and decision-making in the context of scientific policy. Spanish universities represent one sector that has seen signifi cant growth in the use of indicators. These institutions now find themselves in an ever more competitive environment and therefore have a greater need to have knowledge of the performance of their researchers. Against this background, this paper presents a proposal for the creation of Bibliometric Units in Spanish universities and attempts specifically to illustrate both the model and functions of these units based on three pillars: control of information sources related to research, preparing reports, and advice/training. In addition to the theoretical proposal we present different examples from the universities of Navarra and Granada. The text concludes that such units could represent an important opportunity for jobs in the fi eld of Information Science. En los últimos a os la bibliometría evaluativa se han consolidado firmemente como herramienta en la gestión de la investigación y toma de decisiones en el ámbito de la política científica. Una de las instituciones donde más está creciendo este uso es en las universidades espa olas que cada vez se encuentran en un entorno más competitivo y tienen una mayor necesidad de conocer el rendimiento de sus investigadores. Teniendo en cuenta este contexto en el presente trabajo se expone una propuesta para la creación de unidades de bibliometría en las universidades espa olas. El objetivo específico es, por tanto, ilustrar el modelo y funciones de dichas unidades que han de basarse en tres pilares fundamentales: control de las fuentes de la información, realización de informes y asesoramiento y formación. Además de la propuesta teórica se presentan diferentes ejemplos llevados a cabo en las Universidades de Navarra y Granada. El texto concluye subrayando la oportunidad laboral que supondría en el ámbito de la documentación este tipo de unidades.

Torres-Salinas, Daniel,Delgado López-Cózar, Emilio,Jiménez-Contreras, Evaristo
Revista Espa?ola de Documentación Científica , 2009,
Abstract: The aim of this study is to make an analysis of the citation networks between the Spanish Social Science journals using the citations index IN-RECS. Different maps were generated representing the overall structure of Social Sciences and a specific analysis of Library and Information Science was conducted. The indicator betweeness was used as a measure of interdisciplinarity. The results reveal the existence of two main clusters, one formed by the Psychology and the Education and other with a prominent location of the Economics and the Political Science; Sociology is the main connexion between the two clusters. The journals with the highest rate of betweeness were Revista de Educación and Papeles de Economía. The Library and Information Science appears in a marginal side of the different maps. Revista Espa ola de Documentación Científica is the most relevant journal with the largest betweeness rate due to its significant relationships with international journals. The results show that IN-RECS is a useful tool for the structural study of the Spanish Social Sciences. El objetivo de este estudio es realizar un análisis de las redes de citación entre revistas espa olas de ciencias sociales empleando el índice de citas IN-RECS. Se han generado diferentes mapas representando la estructura general de las ciencias sociales y se llevó a cabo un análisis específico del área de Biblioteconomía y Documentación (ByD). Asimismo se empleó el indicador de Intermediación como medida de interdisciplinariedad. Los resultados revelan la existencia de dos clusters. Uno dominado por la Psicología y la Educación y otro donde dominan, principalmente, la Economía y la Ciencia Política, entre ambos clusters actúa de interfaz la Sociología. Las revistas con mayor índice de intermediación son la y Papeles de Economía. La ByD aparece en un lugar marginal de los grafos, dentro de esta especialidad destaca la Revista Espa ola de Documentación Científica con la mayor intermediación debido a sus relaciones con revistas internacionales. Los resultados ponen de manifiesto la utilidad de IN-RECS como fuente de información para el estudio estructural de las ciencias sociales espa olas.
Análisis de la producción de la Universidad de Navarra en revistas de Ciencias Sociales y Humanidades empleando rankings de revistas espa olas y la Web of Science
Torres-Salinas, Daniel,Delgado López-Cózar, Emilio,Jiménez-Contreras, Evaristo
Revista Espa?ola de Documentación Científica , 2009,
Abstract: This paper reports a bibliometric analysis of the output of the Faculties of Social Sciences and Humanities of the University of Navarra, as recorded by publications in scholarly journals over the period 1999-2005. Information for the analysis was gathered from Journal Citation Reports (JCR) and from the Spanish índice de Impacto de las Revistas Espa olas de Ciencias Sociales (IN-RECS), índice de Impacto de las Revistas Espa olas de Ciencias Jurídicas (IN-REJS) and Revistas Espa olas de Ciencias Sociales y Humanidades (RESH). The aim of this work was to determine the adequacy of these ranking systems as bibliometric tools for describing the output in Spanish journals of a university. The results show the University of Navarra published 7281 documents during the studied period, 1908 (26 %) of which were articles in journals. Just over 39 % of the latter were published in Spanish scientific journals, and 12 % in Web of Science journals. The coverage of the ranking systems varies per faculty: the IN-RECJ best covered articles published by the Law faculty; IN-RECS best represented production from Communication and Economics faculties; and RESH best covered production from Humanities faculties. Some 43 % of the studied articles recorded by IN-RECS were published in the first quartile of journals covered by the index; this figure was 42 % with respect to RESH, and 12 % with respect to JCR. Spanish national ranking systems are therefore useful as a complement to bibliometric information provided via the Web of Science and JCR. Se realiza un análisis bibliométrico de la producción en revistas de las facultades de Ciencias Sociales y Humanidades de la Universidad de Navarra durante el período 1999-2005. Se emplean junto al Journal Citation Reports diferentes rankings de revistas espa olas: el índice de Impacto de las Revistas Espa olas de Ciencias Sociales (IN-RECS), índice de Impacto de las Revistas Espa olas de Ciencias Jurídicas (IN-REJS) y Revistas Espa olas de Ciencias Sociales y Humanidades (RESH). El objetivo es estudiar la idoneidad de estos índices como herramienta bibliométrica a la hora de describir la producción en revistas espa olas de una universidad. Respecto a los resultados la Universidad de Navarra publicó un total 7.281 documentos de los cuales 1908 eran trabajos en revistas, es decir, el 26 % de la producción. Del conjunto anterior solo el 39 % fueron en revistas científicas espa olas, y 12 % de la Web of Science. La cobertura de los rankings varía según las facultades, IN-RECJ es óptimo para la Facultad de Derecho, IN-RECS para Comunicación

Revista Espa?ola de Documentación Científica , 2011,
Abstract: This paper presents a bibliometric study analyzing the productivity and citations of female researchers in the fields of social sciences and law in Spain, within the context of Spanish scientific journals. The study was based on the rankings of researchers included in the índice de Impacto de las Revistas Espa olas de Ciencias Sociales (INRECS) and índice de Impacto de las Revistas Espa olas de Ciencias Jurídicas (INRECJ). Eleven different scientific disciplines were analyzed and the final sample consisted of 3,370 researchers, of whom 30 % were women. To study gender differences four variables were selected and analyzed: number of papers, number of citations, number of international citations and citation average. The results show that women in the 11 areas studied have both a lower productivity and a lower number of citations. On the other hand, in some areas women do receive a greater number of international citations and in almost all areas achieve higher citation averages. However the presence of women in the rankings and among the Spanish research elite is still small. Se presenta un estudio bibliométrico cuyo objetivo es analizar la productividad y la citación de las investigadoras en las Ciencias Sociales y Jurídicas en Espa a en el marco de las revistas científi cas nacionales. Como fuente de información se han empleado los rankings de investigadores/as presentes en el índice de Impacto de las Revistas Espa olas de Ciencias Sociales (INRECS) y el índice de Impacto de las Revistas Espa olas de Ciencias Jurídicas (INRECJ). El estudio analiza 11 disciplinas científicas diferentes y la muestra final de investigadores/as extraídos de dichos rankings ha sido de 3.370 de las que el 30 % eran mujeres. Para estudiar las diferencias de géneros se han seleccionado y analizado cuatro variables: el número de trabajos publicados, el número de citas obtenidas, número de citas internacionales y el promedio de citas. Los resultados muestran como las mujeres en las 11 áreas analizadas tienen una menor productividad así como un menor número de citas bruto. Por otro lado las mujeres en diversas áreas sí obtienen un mayor número de citas internacionales y en casi todas alcanzan promedios de citas mayores. Sin embargo aún es escasa la presencia de las mujeres en los rankings y en la élite científica espa ola.
Manipulating Google Scholar Citations and Google Scholar Metrics: simple, easy and tempting
Emilio Delgado Lopez-Cozar,Nicolas Robinson-Garcia,Daniel Torres-Salinas
Computer Science , 2012,
Abstract: The launch of Google Scholar Citations and Google Scholar Metrics may provoke a revolution in the research evaluation field as it places within every researchers reach tools that allow bibliometric measuring. In order to alert the research community over how easily one can manipulate the data and bibliometric indicators offered by Google s products we present an experiment in which we manipulate the Google Citations profiles of a research group through the creation of false documents that cite their documents, and consequently, the journals in which they have published modifying their H index. For this purpose we created six documents authored by a faked author and we uploaded them to a researcher s personal website under the University of Granadas domain. The result of the experiment meant an increase of 774 citations in 129 papers (six citations per paper) increasing the authors and journals H index. We analyse the malicious effect this type of practices can cause to Google Scholar Citations and Google Scholar Metrics. Finally, we conclude with several deliberations over the effects these malpractices may have and the lack of control tools these tools offer

Computer Science , 2014, DOI: 10.3145/epi.2014.jul.03
Abstract: This paper analyzes Altmetric.com, one of the most important altmetric data providers currently used. We have analyzed a set of publications with DOI number indexed in the Web of Science during the period 2011-2013 and collected their data with the Altmetric API. 19% of the original set of papers was retrieved from Altmetric.com including some altmetric data. We identified 16 different social media sources from which Altmetric.com retrieves data. However five of them cover 95.5% of the total set. Twitter (87.1%) and Mendeley (64.8%) have the highest coverage. We conclude that Altmetric.com is a transparent, rich and accurate tool for altmetric data. Nevertheless, there are still potential limitations on its exhaustiveness as well as on the selection of social media sources that need further research.
Altmetrics: New Indicators for Scientific Communication in Web 2.0
Daniel Torres-Salinas,Alvaro Cabezas-Clavijo,Evaristo Jimenez-Contreras
Computer Science , 2013, DOI: 10.3916/C41-2013-05
Abstract: In this paper we review the socalled altmetrics or alternative metrics. This concept raises from the development of new indicators based on Web 2.0, for the evaluation of the research and academic activity. The basic assumption is that variables such as mentions in blogs, number of twits or of researchers bookmarking a research paper for instance, may be legitimate indicators for measuring the use and impact of scientific publications. In this sense, these indicators are currently the focus of the bibliometric community and are being discussed and debated. We describe the main platforms and indicators and we analyze as a sample the Spanish research output in Communication Studies. Comparing traditional indicators such as citations with these new indicators. The results show that the most cited papers are also the ones with a highest impact according to the altmetrics. We conclude pointing out the main shortcomings these metrics present and the role they may play when measuring the research impact through 2.0 platforms.

Abstract: In the past years, the movement of data sharing has been enjoying great popularity. Within this context, Thomson Reuters launched at the end of 2012 a new product inside the Web of Knowledge family: the Data Citation Index. The aim of this tool is to enable discovery and access, from a single place, to data from a variety of data repositories from different subject areas and from around the world. In this short note we present some preliminary results from the analysis of the Data Citation Index. Specifically, we address the following issues: discipline coverage, data types present in the database, and repositories that were included at the time of the study
Towards a Book Publishers Citation Reports. First approach using the Book Citation Index
Daniel Torres-Salinas,Nicolas Robinson-Garcia,Emilio Delgado Lopez-Cozar
Computer Science , 2012,
Abstract: The absence of books and book chapters in the Web of Science Citation Indexes (SCI, SSCI and A&HCI) has always been considered an important flaw but the Thomson Reuters 'Book Citation Index' database was finally available in October of 2010 indexing 29,618 books and 379,082 book chapters. The Book Citation Index opens a new window of opportunities for analyzing these fields from a bibliometric point of view. The main objective of this article is to analyze different impact indicators referred to the scientific publishers included in the Book Citation Index for the Social Sciences and Humanities fields during 2006-2011. This way we construct what we have called the 'Book Publishers Citation Reports'. For this, we present a total of 19 rankings according to the different disciplines in Humanities & Arts and Social Sciences & Law with six indicators for scientific publishers
