The field of Communication in Spain is analyzed, contextualizing Spanish output at a global and local level between the years 2000 and 2020. Based on a descriptive bibliometric analysis of the Communication category of the Social Sciences Citation Index database, part of Web of Science, the impact of the main countries is identified. The weight of the output in the Emerging Sources Citation Index (ESCI) database between 2015 and 2020 is also studied. An analysis of the output by universities in Spain for the period 2010–2020 is also carried out, comparing it with the impact and the works in the first quartile. The results reveal that Spain has been the fourth country in terms of output in Communication in the last decade and that Austria stands out as the country whose works have the greatest impact. It is also observed that 67% of Spain’s works in Communication are published in journals that are indexed in ESCI. The impact of Spanish universities is very close to the world average. The Universitat Pompeu Fabra stands out, publishing the most articles and, furthermore, being the Spanish university with most papers in the first quartile of the JCR in Communication between 2010 and 2020. The study of the Shanghai Ranking by area includes eight Spanish universities, only three of which have output in Communication that comes mainly from professors in this area. The role of the Spanish journals Comunicar and Profesional de la información is notable, as they publish a large fraction of the output by Spanish universities in the Communication field. Finally, this paper presents the challenges of research in Communication, as well as those related to its bibliometric analysis, and a reflection on the problems that affect scientific production and research in this subject area.

Within the current panorama of science evaluation, the limitations of citation indexes to study the social sciences and humanities have been the subject of wide debate. To resolve this situation, different products have been created for use in national contexts, since they cover certain aspects not contained in more international indices. An example is the In-RECS family, where an indicator such as the impact factor of Eugene Garfield is defined, but its contribution lies in the ability to evaluate research in Spain by obtaining citation indicators. This paper thus highlights the need to create new products for research evaluation in general, but particularly in the social sciences and humanities. The context in which different alternatives arise and are developed to evaluate existing journals is presented, along with Dialnet Metrics, a citation index developed by the Dialnet Foundation in collaboration with the EC3 Group and dozens of Spanish universities. Based on an analysis of the citations of source journals from different subject areas, Dialnet Metrics provides indicators to evaluate the research impact at different levels. This bibliometric product enables contextualized analysis at the micro (researchers), meso (journals), and macro (areas and universities) levels. Finally, the content, data volumes, and structure of this citation index are described quantitatively. [ABSTRACT FROM AUTHOR]

The news media's citations of journals, authors, and papers have been used avant la letre to study the impact of science in the lay press and some characteristics of scientific journalism. In this paper, the concepts of press citation and media impact are outlined by analogy to those of scientific citation and scientific impact, establishing their similarities and differences. Some possibilities of study using press citations counts are also outlined, as well as the development of new bibliometric indicators to measure the media impact of science. The analysis of press citations has advantages over alternative metrics (altmetrics) because the press is the main news producer and offers a more consolidated product with a professional filter. However, press citations also have some limitations, mainly the lack of a database of press citations from scientific journals in the international lay press. [ABSTRACT FROM AUTHOR]

The evaluation of scientific journals with bibliometric indicators has been dominated by the Impact factor since the 70s. However Thomson has recently included in the Journal Citation Reports the Eigen factor and the Article influence score. On the other hand Elsevier has included in Scopus the Source normalized impact per paper (SNIP) and the SCImago journal rank (SJR). In this paper we introduce and describe these indicators. Secondly, to study the similarities we analyze correlations of the traditional indicators and the new ones, detailing the results across 27 scientific fields. It was noted that some couples of indicators such as Eigen- Citations, Impact factor-ArticleScore, Impact factor-SJR and SJR-ArticleScore do correlate in many areas. Correlations showed different trends in Science and Social science; therefore, in the last section we discuss the need to take into account the scientific area when selecting an indicator.

A bibliometric analysis of research production in scientific journals, of the Scopus subject category Food Science, between 2003 and 2013, from seventy-one Spanish institutions with at least fifty works published, is presented. Statistical z tests are used for an evaluation of the degree to which an observed number of top-cited papers (top-10%) for an institution differs from the number expected, on the basis of randomness in the selection of papers. A map has been generated that displays inter-institutional collaboration networks; activity and impact values are displayed. The results show the most active institutions, located primarily in Madrid, Cataluña, Valencia, and Murcia, belong to the Spanish National Research Council (CSIC) and Catalonian research institutions.

This paper analyzes the Web applications to manage literature in Biomedical Sciences. We identified, examined and described 28 academic utilities that perform automated analysis. They are user-friendly, and altogether provide better search, retrieval, management and metaanalysis (bibliometrics, network analyses and text mining) of PubMed literature in an efficient, automated, updated and systematized manner that facilitates the simultaneous handling of large quantities of paper records, making it possible for the user to choose the most relevant. All of these initiatives address the needs and challenges of biomedical research in our time. [ABSTRACT FROM AUTHOR]

Zipf's law is a theory based on mathematics and linguistics that analyzes and quantifies how words are distributed within a text. It is possible to represent by graphs and statistical analyzes which are the terms that are repeated over so that a ranking of keywords is created. This research found, through the Zipf's law, variations and uniformities of written academic papers and they presented orally. The oral presentations were inserted in video form on YouTube, it was possible to recover automatically the transcript of the audio. Using a Bash script, texts and transcribed presentations were quantified and organized, thereby creating tag clouds and tables with rankings, facilitating the analysis of the contents. It was possible to identify the spheres of content, identifying common words or not and, mathematically, analyze and compare what was written with what was presented in oral discourse.

Google Scholar is a search engine that specializes in scientific information and in the identification of the citations that academic papers receive, making it a strong competitor for other citations indexes. For this reason, several studies have attempted to evaluate its capacity as a bibliometric tool. Due to this interest, we present an introduction to its use and the advantages and disadvantages versus Scopus and Web of Science. First, its way of collecting information and features of its interface are analyzed. The following section describes the results that Google Scholar generates. Thirdly, we analyze the coverage of information sources and the different document types to be found, showing how this coverage universe offers different citations versus other products. Finally, we specify the standardization problems of Google Scholar and offer a number of precautions that must be taken into account when using Google Scholar as an evaluation tool.

In this paper we show that the aggregation of bibliometric indices is an appropriate way to evaluate scientific production of researchers because it allows us to develop much more precise new bibliometric indices that combine the advantages of each index that is aggregated. [ABSTRACT FROM AUTHOR]
