  • “Altmetrics” Using Google Scholar, Twitter, Mendeley, Facebook
    Pre-Print Version Altmetrics of “altmetrics” using Google Scholar, Twitter, Mendeley, Facebook, Google-plus, CiteULike, Blogs and Wiki Saeed-Ul Hassan, Uzair Ahmed Gillani [email protected] Information Technology University, 346-B Ferozepur Road, Lahore (Pakistan) Abstract: We measure the impact of “altmetrics” field by deploying altmetrics indicators using the data from Google Scholar, Twitter, Mendeley, Facebook, Google- plus, CiteULike, Blogs and Wiki during 2010- 2014. To capture the social impact of scientific publications, we propose an index called alt-index, analogues to h-index. Across the deployed indices, our results have shown high correlation among the indicators that capture social impact. While we observe medium Pearson’s correlation (ρ= .247) among the alt-index and h-index, a relatively high correlation is observed between social citations and scholarly citations (ρ= .646). Interestingly, we find high turnover of social citations in the field compared with the traditional scholarly citations, i.e. social citations are 42.2% more than traditional citations. The social mediums such as Twitter and Mendeley appear to be the most effective channels of social impact followed by Facebook and Google-plus. Overall, altmetrics appears to be working well in the field of “altmetrics”. Keywords: Altmetrics, Social Media, Usage Indicators, Alt-index Pre-Print Version Introduction In scholarly world, altmetrics are getting popularity as to support and/or alternative to traditional citation-based evaluation metrics such as impact factor, h-index etc. (Priem et. al., 2010). The concept of altmetrics was initially proposed in 2010 as a generalization of article level metrics and has its roots in the #altmetrics hashtag (McIntyre et al, 2011).

Horbach*,1,2 [email protected] +31243652730 ORCID: 0000-0003-0406-6261 *Corresponding author 1 Radboud University Nijmegen, Faculty of Science, Institute for Science in Society, P.O. box 9010, 6500 GL Nijmegen, The Netherlands 2 Centre for Science and Technology Studies (CWTS), Faculty of Social Sciences, Leiden University, Wassenaarseweg 62A, 2333 AL Leiden, The Netherlands Abstract In times of public crises, including the current Covid-19 pandemic, rapid dissemination of relevant scientific knowledge is of paramount importance. The duration of scholarly journals’ publication process is one of the main factors hindering quick delivery of new information. While proper editorial assessment and peer review obviously require some time, turnaround times for medical journals can be up to several months, which is undesirable in the era of a crisis. Following initiatives of medical journals and scholarly publishers to accelerate their publication process, this study assesses whether medical journals have indeed managed to speed up their publication process for Covid-19 related articles. It studies the duration of 14 medical journals’ publication process both during and prior to the current pandemic. Assessing a total of 669 articles, the study concludes that medical journals have indeed drastically accelerated the publication process for Covid-19 related articles since the outbreak of the pandemic.

  • How Comprehensive Is the Pubmed Central Open Access Full-Text Database? ⋆
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Illinois Digital Environment for Access to Learning and Scholarship Repository How comprehensive is the PubMed Central Open Access full-text database? ⋆ Jiangen He1[0000−0002−3950−6098] and Kai Li1[0000−0002−7264−365X] Department of Information Science, Drexel University, Philadelphia PA, 19104, USA. [email protected], [email protected] Abstract. The comprehensiveness of database is a prerequisite for the quality of scientific works established on this increasingly significant infrastructure. This is especially so for large-scale text-mining analy- ses of scientific publications facilitated by open-access full-text scientific databases. Given the lack of research concerning the comprehensiveness of this type of academic resource, we conducted a project to analyze the coverage of materials in the PubMed Central Open Access Subset (PMCOAS), a popular source for open-access scientific publications, in terms of the PubMed database. The preliminary results show that the PMCOAS coverage is in a rapid increase in recent years, despite the vast difference by MeSH descriptor. Keywords: Database coverage · PubMed Central Open Access· PubMed. 1 Introduction Database has become a central piece of scientific infrastructure in our contem- porary data-driven mode of scientific practice. The increasing volumes of data stored in structured formats gradually became an indispensable source for scien- tific discoveries in nearly every knowledge domain. However, one question that often shrouds this source is how comprehensive the database is as compared to the reality the database is claimed to represent. A large number of studies in the field of quantitative studies of science have been devoted to this question since the end of the 20th century: they have compared various parameters, especially the number of documents, references, and journals covered, among databases such as Web of Science, Scopus, and Google Scholar [2, 3, 5, 8, 6, 7].

  • A Scientometric Study of Pubmed-Indexed Endodontic Articles: a Comparison Between Iran and Other Regional Countries
    EDITORIAL 1 2 3 Mohammad Jafar Eghbal DDS, MS, Negar Davari Ardakani MSc, PhD, Saeed Asgary DDS, MS A Scientometric Study of PubMed-Indexed Endodontic Articles: A Comparison between Iran and Other Regional Countries 1. Dental Research Center, Iranian Center for Endodontic Research, Dental School, Shahid Beheshti University of Medical Sciences, Tehran, Iran 2. Linguistics Department, Literature Faculty, Shahid Beheshti University of Medical Sciences, Tehran, Iran 3. Iranian Center for Endodontic Research, Dental Research Center, Dental School, Shahid Beheshti University of Medical Sciences, Tehran, Iran Introduction: Based on Iran’s 20-year prospective national vision document, Iran may be seen as the most developed country in science and technology in the region by 2025. In this report, bibliometric indicators are used to compare the research productivity in endodontics between Iran and 28 selected Asian countries. Materials and Methods: Medical Subject Headings keyword-searching of PubMed up to 2012 was conducted to compare the scientific publications in Iran and neighboring countries (Middle East, Middle Asia, Caucasus and EMRO countries). Highest 5 PubMed-indexed endodontic journals were also searched to retrieve the number of published articles of the top five countries. Data were extracted, tabulated and compared to identify the ranks as well as trends. Results: The results confirm that there are many differences in scientific endodontic publications between the studied countries; Iran ranked second in endodontic research productivity compared to Turkey in 2011. However, Iran attained first place in 2010 as well as the most positive publication trend in PubMed-indexed endodontic journals. Conclusion: Although Iran was in second rank in the region last year, the positive trend in published endodontic research papers is considered a sign of future success in acquiring Iran’s vision.

  • An Initiative to Track Sentiments in Altmetrics
    Halevi, G., & Schimming, L. (2018). An Initiative to Track Sentiments in Altmetrics. Journal of Altmetrics, 1(1): 2. DOI: https://doi.org/10.29024/joa.1 PERSPECTIVE An Initiative to Track Sentiments in Altmetrics Gali Halevi and Laura Schimming Icahn School of Medicine at Mount Sinai, US Corresponding author: Gali Halevi ([email protected]) A recent survey from Pew Research Center (NW, Washington & Inquiries 2018) found that over 44 million people receive science-related information from social media channels to which they subscribe. These include a variety of topics such as new discoveries in health sciences as well as “news you can use” information with practical tips (p. 3). Social and news media attention to scientific publications has been tracked for almost a decade by several platforms which aggregate all public mentions of and interactions with scientific publications. Since the amount of comments, shares, and discussions of scientific publications can reach an audience of thousands, understanding the overall “sentiment” towards the published research is a mammoth task and typically involves merely reading as many posts, shares, and comments as possible. This paper describes an initiative to track and provide sentiment analysis to large social and news media mentions and label them as “positive”, “negative” or “neutral”. Such labels will enable an overall understanding of the content that lies within these social and news media mentions of scientific publications. Keywords: sentiment analysis; opinion mining; scholarly output Background Traditionally, the impact of research has been measured through citations (Cronin 1984; Garfield 1964; Halevi & Moed 2015; Moed 2006, 2015; Seglen 1997). The number of citations a paper receives over time has been directly correlated to the perceived impact of the article.

Louis Houle McGill University Canada [email protected] Abstract Since its debut I November 2004, librarians have raised several criticisms at Google Scholar (GS) such as its inconsistency of coverage and its currency and scope of coverage. It may have been true in the early years of Google Scholar but is this still through twelve years after? Is this sufficient to ignore it totally either in our information literacy programs or evaluate its value against the values of subscription-based abstracts and indexes? In this era of severe budget constraints that libraries are facing, can we imagine of substituting most or all of our subject databases with the free access of Google Scholar for discoverability? How much overlap between our databases and Google Scholar? How reliable is Google Scholar? How stable is its content over time? Open Access is getting to be the predominant form of getting access to peer reviewed articles. Many new non-traditional tools (institutional repositories, social media and peer to peer sites) are available out there to retrieve the full-text of peer reviewed articles.

Romero-Ortiz This article was originally published as: Machin-Mastromatteo, J.D., Uribe-Tirado, A., and Romero-Ortiz, M. E. (2016). Piracy of scientific papers in Latin America: An analysis of Sci-Hub usage data. Information Development, 32(5), 1806–1814. http://dx.doi.org/10.1177/0266666916671080 Abstract Sci-Hub hosts pirated copies of 51 million scientific papers from commercial publishers. This article presents the site’s characteristics, it criticizes that it might be perceived as a de-facto component of the Open Access movement, it replicates an analysis published in Science using its available usage data, but limiting it to Latin America, and presents implications caused by this site for information professionals, universities and libraries. Keywords: Sci-Hub, piracy, open access, scientific articles, academic databases, serials crisis Scientific articles are vital for students, professors and researchers in universities, research centers and other knowledge institutions worldwide. When academic publishing started, academies, institutions and professional associations gathered articles, assessed their quality, collected them in journals, printed and distributed its copies; with the added difficulty of not having digital technologies. Producing journals became unsustainable for some professional societies, so commercial scientific publishers started appearing and assumed printing, sales and distribution on their behalf, while academics retained the intellectual tasks. Elsevier, among the first publishers, emerged to cover operations costs and profit from sales, now it is part of an industry that grew from the process of scientific communication; a 10 billion US dollar business (Murphy, 2016).

Dubey Librarian R.S Mundle Dharampeth Arts and Commerce College, Nagpur, India [email protected] Abstract To understand the global research trend of the scientific publication on coronavirus, this scientometric study was carried out for the period 2002 to 2019 based on scientometric indicators such as growth of publication, productive authors and institutions, collaboration among authors and institutions, the hotspot of research area and the citation pattern. A total of 8541 records downloaded from PubMed formed the dataset for the study and were analysed using Bibexcel and VOSviewer. The findings reveal that the research on coronavirus was noticeable but it was not significant. A correlation between the number of publications and emergence of SARS in 2002 and MERS in 2012 was also visible. The trend of publication was found to be fluctuating during the period of study. The findings demonstrate that collaboration among institutions was not very strong.

  • Do You Speak Open Science? Resources and Tips to Learn the Language
    Do You Speak Open Science? Resources and Tips to Learn the Language. Paola Masuzzo1, 2 - ORCID: 0000-0003-3699-1195, Lennart Martens1,2 - ORCID: 0000- 0003-4277-658X Author Affiliation 1 Medical Biotechnology Center, VIB, Ghent, Belgium 2 Department of Biochemistry, Ghent University, Ghent, Belgium Abstract The internet era, large-scale computing and storage resources, mobile devices, social media, and their high uptake among different groups of people, have all deeply changed the way knowledge is created, communicated, and further deployed. These advances have enabled a radical transformation of the practice of science, which is now more open, more global and collaborative, and closer to society than ever. Open science has therefore become an increasingly important topic. Moreover, as open science is actively pursued by several high-profile funders and institutions, it has fast become a crucial matter to all researchers. However, because this widespread interest in open science has emerged relatively recently, its definition and implementation are constantly shifting and evolving, sometimes leaving researchers in doubt about how to adopt open science, and which are the best practices to follow. This article therefore aims to be a field guide for scientists who want to perform science in the open, offering resources and tips to make open science happen in the four key areas of data, code, publications and peer-review. The Rationale for Open Science: Standing on the Shoulders of Giants One of the most widely used definitions of open science originates from Michael Nielsen [1]: “Open science is the idea that scientific knowledge of all kinds should be openly shared as early as is practical in the discovery process”.
