Relationship among research collaboration, number of documents and number of citations. A case study in Spanish computer science production in 2000-2009.

This paper analyzes the relationship among research collaboration, number of documents and number of citations of computer science research activity. It analyzes the number of documents and citations and how they vary by number of authors. They are also analyzed (according to author set cardinality) under different circumstances, that is, when documents are written in different types of collaboration, when documents are published in different document types, when documents are published in different computer science subdisciplines, and, finally, when documents are published by journals with different impact factor quartiles. To investigate the above relationships, this paper analyzes the publications listed in the Web of Science and produced by active Spanish university professors between 2000 and 2009, working in the computer science field. Analyzing all documents, we show that the highest percentage of documents are published by three authors, whereas single-authored documents account for the lowest percentage. By number of citations, there is no positive association between the author cardinality and citation impact. Statistical tests show that documents written by two authors receive more citations per document and year than documents published by more authors. In contrast, results do not show statistically significant differences between documents published by two authors and one author. The research findings suggest that international collaboration results on average in publications with higher citation rates than national and institutional collaborations. We also find differences regarding citation rates between journals and conferences, across different computer science subdisciplines and journal quartiles as expected. Finally, our impression is that the collaborative level (number of authors per document) will increase in the coming years, and documents published by three or four authors will be the trend in computer science literature

Impact of open access on citation of scholarly publications in the field of civil engineering

The development of science is accompanied by growth of scholarly publications, primarily in the form of articles in peer-reviewed journals. Scientific work is often evaluated through the number of scientific publications in international journals and their citations. This article discusses the impact of open access (OA) on the number of citations for an institution from the field of civil engineering. We analyzed articles, published in 2007 in 14 international journals with impact factor, which are included in the Journal Citation Reports subject category “Civil Engineering”. The influence of open access on the number of citations was analyzed. The aim of our research was to determine if open access articles from the field of civil engineering receive more citations than non-open access articles. Based on the value of impact factor and ranking in quartiles, we also looked at the influence of the rank of journals on the number of citations, separately for OA and Non OA articles, in databases Web of Science (WOS), Scopus and Google Scholar. For 2,026 studied articles we found out that 22 % of them were published as OA articles. They received 29 % of all citations in the observed period. We can conclude by the significance level 5 % or less that in the databases WOS and Scopus the articles from top ranked journals (first quartile) achieved more citations than Non OA articles. This argument can be confirmed for some other journals from second quartile as well, while for the journals ranked into the third quartile it can’t be confirmed. This could be confirmed only partly for journals from the second quartile, and would not be confirmed for journals ranked into the third quartile. This shows that open access is not a sufficient condition for citation, but increases the number of citations for articles published in journals with high impact

Indicadores bibliométricos para el análisis de la actividad de una institución multidisciplinar: el CSIC

An overview is provided of CSIC’s research performance in the context of Spain, through a study of its scholarly production in the Web of Science database, complemented with ICYT and ISOC, during the period 2004-2009. The eight scientific and technical areas in which CSIC’s centers are organised differ as to their national or international research orientation, their basic or applied nature, the degree of their collaboration and the size of their research teams; all of which influences each area’s publication and citation practices as well as its WoS-based productivity. The specific features of the different areas must be thoroughly understood in order to expound on and interpret properly the results of studies dealing with research evaluation.Este artículo ofrece una visión general de la actividad investigadora del CSIC en el contexto de España a través del estudio de su producción científica en la base de datos Web of Science, complementada con ICYT e ISOC, durante el período 2004-2009. Las ocho áreas científico-técnicas en las que se organizan los centros del CSIC difieren en la orientación nacional o internacional de su investigación, su carácter básico o aplicado, la incidencia de la colaboración, y el tamaño de los grupos de investigación; todo lo cual influye sobre las prácticas de publicación y citación imperantes en cada área, y sobre su productividad derivada de WoS. Se señala la importancia de conocer las especificidades de las distintas áreas para plantear e interpretar adecuadamente los resultados de los estudios de evaluación de la actividad científica

Early-career factors largely determine the future impact of prominent researchers: evidence across eight scientific fields

Abstract Can we help predict the future impact of researchers using early-career factors? We analyze early-career factors of the world’s 100 most prominent researchers across 8 scientific fields and identify four key drivers in researchers’ initial career: working at a top 25 ranked university, publishing a paper in a top 5 ranked journal, publishing most papers in top quartile (high-impact) journals and co-authoring with other prominent researchers in their field. We find that over 95% of prominent researchers across multiple fields had at least one of these four features in the first 5 years of their career. We find that the most prominent scientists who had an early career advantage in terms of citations and h-index are more likely to have had all four features, and that this advantage persists throughout their career after 10, 15 and 20 years. Our findings show that these few early-career factors help predict researchers’ impact later in their careers. Our research thus points to the need to enhance fairness and career mobility among scientists who have not had a jump start early on

A Survey of Retracted Articles from Three OIC Member Countries (Iran, Turkey, & Egypt) in the Web of Science (WoS)

The present study examines the retracted articles from three OIC member countries (Iran, Turkey, and Egypt) in the Web of Science (WoS). All articles from Iran, Turkey, and Egypt, published in the journals indexed in the WoS and retracted due to scientific misconduct, consisted of the research population. This analytical survey examined the retracted articles regarding research areas, periods, cumulative citations, and names of collaborating authors and countries by country, discipline, and field via scientometrics. With 38%, Iran has the most retracted articles in various fields and scientific fields. Most of the retracted articles are related to basic sciences, medicine, and engineering, respectively. In the analysis of statistics, the publisher of retracted articles, in Iran, Turkey, and Egypt, we can name two countries, the United States and the United Kingdom, which are among the publishers with many publishing activities in all countries. Considering that the number of retracted articles globally has increased significantly, informing researchers and those involved in scientific journals and regular monitoring of citation performance of journals can prevent similar events in the future.https://dorl.net/dor/20.1001.1.20088302.2022.20.1.16.
