Abstract

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.

Abstract

Institutional offices for the communication and dissemination of science are gaining in importance at Spanish universities, and their activities can contribute to increasing the visibility and reputation of researchers. The objective of this study is to analyze the relations between the institutional communication of research results to the public and the impact and academic visibility of scientific papers. For this purpose, science communication and dissemination undertaken through press releases on R+D+i results from the Science Culture and Innovation Unit (SCIU) at Universidad Carlos III de Madrid (UC3M) were selected as a case study. This SCIU was chosen because it has published yearly reports for more than a decade on the impact in the media of its press releases. Press dossiers of the last five years available (2014-2018) were examined, and a database was created of the citations received by texts published in scientific journals indexed in the Web of Science as well as their mentions on social networks through the company Altmetric.com. After that, this information was statistically analyzed. The main results show that the journal impact index is important for obtaining academic citations or appearing in Twitter conversations. However, the influence of the journal impact factor turns out to be lower when it comes to popularizing scientific publications in the media. Furthermore, the statistical evidence points to the fact that scientific publications disseminated through the SCIU receive proportionally more citations than research that has not been disseminated through the institutional channel.
