Uncited articles and the dispersion of citations in the scientific literature

Map of co-citation prepared by the authors with the VOSviewer software.

Questioning Bradford’s law, whose interpretation in bibliometrics states that most citations are concentrated in a few journals and articles, a recent study highlights the importance of uncited articles and their influence on citation concentration. For the authors, uncited articles should be included in the analysis to provide a more comprehensive understanding of citation patterns across time, disciplines, and geographic regions. Read More →

Mapping output in content analysis in SciELO Brazil indicates a technique that is caught in a time warp

On the right, a woman sitting at a table with a notebook. On the screen, different types of graphics. In the background, geometric graphic elements and leaf shape. Shades of salmon and purple.

A scientometric review on the use of content analysis in SciELO Brasil showed a notable concentration of citations from Laurence Bardin’s manual, whose use continues to grow. As the work has not had updates in the last two decades, we can say that the use of the technique may be caught in a time warp. Read More →

Open Access and Closed Research. Who benefits from the APC?

Recent research published in Scientometrics raises questions about unforeseen consequences of the spread of Open Access scientific publishing that have to do with the growth of total expenditures and who would be the economic beneficiaries of this paradigm shift. Read More →

Research assessment should go beyond comparing impact metrics

The assessment of research results that mainly relies on citation-based metrics has limitations that lead to distortions in the management of human and financial resources in research institutions around the world. The innovative Agreement on Reforming Research Assessment, created by the initiative of the European Commission and organizations from this continent with the support of 350 public and private organizations from more than 40 countries, has just been published, and establishes criteria that value qualitative assessment and limit the use of quantitative indicators.

How altmetrics are used to evaluate scientific output in Latin America

Altmetrics are a group of alternative metrics that capture mentions made to scientific papers on social networks, news sites and blogs; policies and patents; Wikipedia, and other sources to assess the impact of publications on the social web. A study using journals and articles from the SciELO network in Latin America was carried out to qualify the web presence of Latin American research results and explore the potential of altmetrics.

Presence in Mega Indexes Project proposes to create more visibility to the journals in the SciELO Brazil Collection

Seeking out to increase international presence, facilitate access to information, and improve the generation of quality indicators of the SciELO journals, a project with the support of the Scopus Brazil team to maximize the indexing of the SciELO’s journals starting with the Brazil collection is currently in progress. The process that embraces about 75 journals started with a pre-analysis followed by a webinar, the sending of collected data to Scopus and update of the journal’s informative pages in the SciELO site. Text available only in Portuguese. Read More →

Bibliometrics: a new threat to zoological taxonomy?

One of the backbones of the life sciences, taxonomy —the science of biodiversity—suffers from multiples impediments, including the use of bibliometric indexes by organizations. These days such indexes play a big role in the scientific decisions. However, what for-profit companies, which own these bibliometric platforms, have to do with science? Read More →

JCR, Kafka, and MAI!

For the second time, the Anais da Academia Brasileira de Ciências was surprised to find out that about one quarter of the papers of an issue were gone missing from the Jornal Citation Reports platform, a problem that should come to the attention of the publishing and evaluation industry. Some objective ways to appraise the performance of specific volumes or areas of a journal are presented. Read More →

The Coronavirus (COVID-19) outbreak highlights serious deficiencies in scholarly communication [Originally published in the LSE Impact blog in March/2020]

As research and government responses to the COVID-19 outbreak escalate in the face of a global public health crisis, Vincent Larivière, Fei Shu and Cassidy R. Sugimoto reflect on efforts to make research on this subject more widely available. Arguing that a narrow focus on research published in high ranking journals predominantly in English has impeded research efforts, they suggest that the renewed emphasis on carrying out open research on the virus presents an opportunity to reassess how research and scholarly communication systems serve the public good.

Posting preprints before peer review is associated with increased visibility and citation of published articles

The communication of research results through preprints has been increasing significantly, as by the increasing number of manuscripts deposited on bioRxiv, the preprint server for biology and life sciences. However, only a small fraction of the research papers indexed in PubMed started as preprints in bioRxiv. But what would undecided authors about preprints say if they knew that articles that have associated preprints have a 49% higher Altmetric index and 36% more citations? This is what shows a recent study published in eLife. Read More →

Working to the rule – How bibliometric targets distorted Italian research [Originally published in LSE Impact of Social Sciences blog in November/2019]

As Goodhart’s law states: “when a measure becomes a target, it ceases to be a good measure”. Using bibliometrics to measure and assess researchers has become increasingly common, but does implementing these policies therefore devalue the metrics they are based on? In this post Alberto Baccini, Giuseppe De Nicolao and Eugenio Petrovich, present evidence from a study of Italian researchers revealing how the introduction of bibliometric targets into the Italian academy has changed the way Italian academics cite and use the work of their colleagues.

Google Scholar, Web of Science or Scopus, which gives us better indexing coverage?

Recent analysis of the indexing coverage of the Google Scholar, Web of Science, and Scopus databases shows that higher values do not always mean higher quality or better indexing, as the inclusion of more lower-quality or lower-impact documents may reflect in other aspects of the analysis and, depending on the type of assessment, it should be necessary to eliminate certain types of documents from the citation count.

The 2019 Workshop on Open Scientometric Data Infrastructures at Leiden University [Originally published in the CWTS blog in August/2019]

The Open Scientometric Data Infrastructures Workshop took place at CWTS on 28 February and 1 March 2019. Over the course of two days, 14 researchers from CWTS and other research institutes and universities came together to discuss current projects and initiatives regarding open scientometric data infrastructures. This blog post provides a summary on the presentations and discussions held at the event. Read More →

Registry of [Open] Scientometric Data Sources – a collaborative directory of scientometric data sources [Originally published in the TIB Blog in May/2019]

This post introduces the development of an open accessible registry of data sources for scientometric information envisaging to get feedback and collaboration of the information science communities towards a global coverage. Read More →

Web presence and social media metrics from articles shared on Twitter – Interview with Stefanie Haustein

Knowing how and by whom articles are shared on social media can help the challenging task of qualifying alternative metrics indicators. In this interview, Stefanie Haustein, assistant professor at the University of Ottawa’s School of Information Studies in Canada and co-director of the ScholCommLab, addresses the role of social networks such as Twitter as a data source for altmetrics. She also looks at the role journals play in the dissemination of their articles on Twitter and investigates how scholarly articles from Brazil and Brazilian Twitter users tweet about scholarly outputs.
