Features and implications of Emerging Sources Citation Index (Thomson Reuters): Journals in a transitional status

With the launch of the Emerging Sources Citation Index (ESCI), Thomson Reuters has created a set of expectations. The Web of Science has become the most comprehensive research platform of journal evaluation. ESCI acts as the waiting room before Thomson technicians check whether journals meet the quality requirements to be indexed in the Science Citation Index (SCI), Social SCI, and Arts & Humanities Citation Index databases. ESCI is characterized by its multidisciplinary coverage and its increase in geographic coverage, now reaching non Anglo-Saxon countries. ESCI increases Thomas Reuters range without sacrificing the quality of its reference products. In addition, it contributes to the transparency of the evaluation and selection process

STEM Abstracting and Indexing (A&I) Tool Overlap Analysis in 2020: An Open Science Informed Approach Amid Pandemic Budgets

Objectives: Compare journal coverage of abstract and indexing tools commonly used within academic science and engineering research. Methods: Title lists of Compendex, Inspec, Reaxys, SciFinder, and Web of Science were provided by their respective publishers. These lists were imported into Excel and the overlap of the ISSN/EISSNs and journal titles was determined using the VLOOKUP command, which determines if the value in one cell can be found in a column of other cells. Results: There is substantial overlap between the Web of Science’s Science Citation Index Expanded and the Emerging Sources Citation Index, the largest database with 17,014 titles, and Compendex (63.6%), Inspec (71.0%), Reaxys (67.0%), and SciFinder (75.8%). SciFinder also overlaps heavily with Reaxys (75.9%). Web of Science and Compendex combined contain 77.6% of the titles within Inspec. Conclusion: Flat or decreasing library budgets combined with increasing journal prices result in an unsustainable system that will require a calculated allocation of resources at many institutions. The overlap of commonly indexed journals among abstracting and indexing tools could serve as one way to determine how these resources should be allocated

COVID-19 publications: Database coverage, citations, readers, tweets, news, Facebook walls, Reddit posts

The published version can be accessed at the following link on the publisher’s website: https://doi.org/10.1162/qss_a_00066The COVID-19 pandemic requires a fast response from researchers to help address biological, medical and public health issues to minimize its impact. In this rapidly evolving context, scholars, professionals and the public may need to quickly identify important new studies. In response, this paper assesses the coverage of scholarly databases and impact indicators during 21 March to 18 April 2020. The rapidly increasing volume of research, is particularly accessible through Dimensions, and less through Scopus, the Web of Science, and PubMed. Google Scholar’s results included many false matches. A few COVID-19 papers from the 21,395 in Dimensions were already highly cited, with substantial news and social media attention. For this topic, in contrast to previous studies, there seems to be a high degree of convergence between articles shared in the social web and citation counts, at least in the short term. In particular, articles that are extensively tweeted on the day first indexed are likely to be highly read and relatively highly cited three weeks later. Researchers needing wide scope literature searches (rather than health focused PubMed or medRxiv searches) should start with Dimensions (or Google Scholar) and can use tweet and Mendeley reader counts as indicators of likely importance

Software tools for conducting bibliometric analysis in science: An up-to-date review

Bibliometrics has become an essential tool for assessing and analyzing the output of scientists, cooperation between universities, the effect of state-owned science funding on national research and development performance and educational efficiency, among other applications. Therefore, professionals and scientists need a range of theoretical and practical tools to measure experimental data. This review aims to provide an up-to-date review of the various tools available for conducting bibliometric and scientometric analyses, including the sources of data acquisition, performance analysis and visualization tools. The included tools were divided into three categories: general bibliometric and performance analysis, science mapping analysis, and libraries; a description of all of them is provided. A comparative analysis of the database sources support, pre-processing capabilities, analysis and visualization options were also provided in order to facilitate its understanding. Although there are numerous bibliometric databases to obtain data for bibliometric and scientometric analysis, they have been developed for a different purpose. The number of exportable records is between 500 and 50,000 and the coverage of the different science fields is unequal in each database. Concerning the analyzed tools, Bibliometrix contains the more extensive set of techniques and suitable for practitioners through Biblioshiny. VOSviewer has a fantastic visualization and is capable of loading and exporting information from many sources. SciMAT is the tool with a powerful pre-processing and export capability. In views of the variability of features, the users need to decide the desired analysis output and chose the option that better fits into their aims

The structural role of the core literature in history

The intellectual landscapes of the humanities are mostly uncharted territory. Little is known on the ways published research of humanist scholars defines areas of intellectual activity. An open question relates to the structural role of core literature: highly cited sources, naturally playing a disproportionate role in the definition of intellectual landscapes. We introduce four indicators in order to map the structural role played by core sources into connecting different areas of the intellectual landscape of citing publications (i.e. communities in the bibliographic coupling network). All indicators factor out the influence of degree distributions by internalizing a null configuration model. By considering several datasets focused on history, we show that two distinct structural actions are performed by the core literature: a global one, by connecting otherwise separated communities in the landscape, or a local one, by rising connectivity within communities. In our study, the global action is mainly performed by small sets of scholarly monographs, reference works and primary sources, while the rest of the core, and especially most journal articles, acts mostly locally

Benchmarking some Portuguese S&T system research units: 2nd Edition

The increasing use of productivity and impact metrics for evaluation and comparison, not only of individual researchers but also of institutions, universities and even countries, has prompted the development of bibliometrics. Currently, metrics are becoming widely accepted as an easy and balanced way to assist the peer review and evaluation of scientists and/or research units, provided they have adequate precision and recall. This paper presents a benchmarking study of a selected list of representative Portuguese research units, based on a fairly complete set of parameters: bibliometric parameters, number of competitive projects and number of PhDs produced. The study aimed at collecting productivity and impact data from the selected research units in comparable conditions i.e., using objective metrics based on public information, retrievable on-line and/or from official sources and thus verifiable and repeatable. The study has thus focused on the activity of the 2003-06 period, where such data was available from the latest official evaluation. The main advantage of our study was the application of automatic tools, achieving relevant results at a reduced cost. Moreover, the results over the selected units suggest that this kind of analyses will be very useful to benchmark scientific productivity and impact, and assist peer review.Comment: 26 pages, 20 figures F.
