"Prevalence and Citation Advantage of Gold Open Access n the Subject Areas of the Scopus Database"

Posted in Open Access, Publishing, Scholarly Journals, Scholarly Metrics on August 23rd, 2017

Pablo Dorta-González and Yolanda Santana-Jiménez have self-archived "Prevalence and Citation Advantage of Gold Open Access n the Subject Areas of the Scopus Database."

Here's an excerpt:

In the present paper, an analysis of gold OA from across all areas of research -the 27 subject areas of the Scopus database- is realized. As a novel contribution, this paper takes a journal-level approach to assessing the OA citation advantage, whereas many others take a paper-level approach. Data were obtained from Scimago Lab, sorted using Scopus database, and tagged as OA/non-OA using the DOAJ list. Jointly with the OA citation advantage, the OA prevalence as well as the differences between access types (OA vs. non-OA) in production and referencing are tested. A total of 3,737 OA journals (16.8%) and 18,485 non-OA journals (83.2%) published in 2015 are considered. As the main conclusion, there is no generalizable gold OA citation advantage at journal level.

"DataCite as a Novel Bibliometric Source: Coverage, Strengths and Limitations"

Posted in Data Curation, Open Data, and Research Data Management, Scholarly Metrics on July 21st, 2017

Nicolas Robinson-Garcia et al. have self-archived "DataCite as a Novel Bibliometric Source: Coverage, Strengths and Limitations."

Here's an excerpt:

This paper explores the characteristics of DataCite to determine its possibilities and potential as a new bibliometric data source to analyze the scholarly production of open data. Open science and the increasing data sharing requirements from governments, funding bodies, institutions and scientific journals has led to a pressing demand for the development of data metrics. As a very first step towards reliable data metrics, we need to better comprehend the limitations and caveats of the information provided by sources of open data. In this paper, we critically examine records downloaded from the DataCite's OAI API and elaborate a series of recommendations regarding the use of this source for bibliometric analyses of open data. We highlight issues related to metadata incompleteness, lack of standardization, and ambiguous definitions of several fields. Despite these limitations, we emphasize DataCite's value and potential to become one of the main sources for data metrics development.

"A Century of Science: Globalization of Scientific Collaborations, Citations, and Innovations"

Posted in Publishing, Scholarly Communication, Scholarly Journals, Scholarly Metrics on April 22nd, 2017

Yuxiao Dong, Hao Ma, Zhihong Shen, and Kuansan Wang have self-archived "A Century of Science: Globalization of Scientific Collaborations, Citations, and Innovations."

Here's an excerpt:

In this work, we study the evolution of scientific development over the past century by presenting an anatomy of 89 million digitalized papers published between 1900 and 2015. We find that science has benefited from the shift from individual work to collaborative effort, with over 90% of the world-leading innovations generated by collaborations in this century, nearly four times higher than they were in the 1900s. We discover that rather than the frequent myopic- and self-referencing that was common in the early 20th century, modern scientists instead tend to look for literature further back and farther around. Finally, we also observe the globalization of scientific development from 1900 to 2015, including 25-fold and 7-fold increases in international collaborations and citations, respectively, as well as a dramatic decline in the dominant accumulation of citations by the US, the UK, and Germany, from 95% to 50% over the same period.

"Transitioning from a Conventional to a’‘Mega’ Journal: A Bibliometric Case Study of the Journal Medicine"

Posted in Open Access, Publishing, Scholarly Metrics on April 10th, 2017

Simon Wakeling et al. have published "Transitioning from a Conventional to a'‘Mega' Journal: A Bibliometric Case Study of the Journal Medicine" in Publications.

Here's an excerpt:

This study compares the bibliometric profile of the journal Medicine before and after its transition to the OAMJ model. Three standard modes of bibliometric analysis are employed, based on data from Web of Science: journal output volume, author characteristics, and citation analysis. The journal’s article output is seen to have grown hugely since its conversion to an OAMJ, a rise driven in large part by authors from China. Articles published since 2015 have fewer citations, and are cited by lower impact journals than articles published before the OAMJ transition.

"What Makes Papers Visible on Social Media? An Analysis of Various Document Characteristics"

Posted in Publishing, Scholarly Journals, Scholarly Metrics on March 21st, 2017

Zohreh Zahedi et al. have self-archived "What Makes Papers Visible on Social Media? An Analysis of Various Document Characteristics."

Here's an excerpt:

In this study we have investigated the relationship between different document characteristics and the number of Mendeley readership counts, tweets, Facebook posts, mentions in blogs and mainstream media for 1.3 million papers published in journals covered by the Web of Science (WoS). It aims to demonstrate that how factors affecting various social media-based indicators differ from those influencing citations and which document types are more popular across different platforms. Our results highlight the heterogeneous nature of altmetrics, which encompasses different types of uses and user groups engaging with research on social media.

"The Coverage of Microsoft Academic: Analyzing the Publication Output of a University"

Posted in Google and Other Search Engines, Publishing, Scholarly Journals, Scholarly Metrics on March 21st, 2017

Sven E. Hug and Martin P. Braendle have self-archived "The Coverage of Microsoft Academic: Analyzing the Publication Output of a University."

Here's an excerpt:

This is the first in-depth study on the coverage of Microsoft Academic (MA). The coverage of a verified publication list of a university was analyzed on the level of individual publications in MA, Scopus, and Web of Science (WoS). Citation counts were analyzed and issues related to data retrieval and data quality were examined. . . . MA surpasses Scopus and WoS clearly with respect to book-related document types and conference items but falls slightly behind Scopus with regard to journal articles. MA shows the same biases as Scopus and WoS with regard to the coverage of the social sciences and humanities, non-English publications, and open-access publications. Rank correlations of citation counts are high between MA and the benchmark databases. . . .Given the fast and ongoing development of MA, we conclude that MA is on the verge of becoming a bibliometric superpower. However, comprehensive studies on the quality of MA data are still lacking.

"A Data Citation Roadmap for Scientific Publishers"

Posted in Data Curation, Open Data, and Research Data Management, Publishing, Scholarly Journals, Scholarly Metrics on January 26th, 2017

Helena Cousijn et al. have self-archived "A Data Citation Roadmap for Scientific Publishers."

Here's an excerpt:

This article presents a practical roadmap for scholarly publishers to implement data citation in accordance with the Joint Declaration of Data Citation Principles (JDDCP), a synopsis and harmonization of the recommendations of major science policy bodies. It was developed by the Publishers Early Adopters Expert Group as part of the Data Citation Implementation Pilot (DCIP) project, an initiative of FORCE11.org and the NIH BioCADDIE program. The structure of the roadmap presented here follows the 'life of a paper' workflow and includes the categories Pre-submission, Submission, Production, and Publication. The roadmap is intended to be publisher-agnostic so that all publishers can use this as a starting point when implementing JDDCP-compliant data citation.

"CiteScore—Flawed but Still A Game Changer"

Posted in Scholarly Metrics on December 13th, 2016

Phil Davis has published "CiteScore—Flawed but Still A Game Change" in The Scholarly Kitchen.

Here's an excerpt:

The CiteScore metric is controversial because of its overt biases against journals that publish a lot of front-matter. Nevertheless, for most academic journals, CiteScore will provide rankings that are similar to the Impact Factor.

"Does Evaluative Scientometrics Lose Its Main Focus on Scientific Quality by the New Orientation towards Societal Impact?"

Posted in Publishing, Scholarly Journals, Scholarly Metrics on December 9th, 2016

Lutz Bornmann and Robin Haunschild have published "Does Evaluative Scientometrics Lose Its Main Focus on Scientific Quality by the New Orientation towards Societal Impact?" in Scientometrics.

Here's an excerpt:

In this Short Communication, we have outlined that the current revolution in scientometrics does not only imply a broadening of the impact perspective, but also the devaluation of quality considerations in evaluative contexts. Impact might no longer be seen as a proxy for quality, but in its original sense: the simple resonance in some sectors of society. This is an alarming development, because fraudulent research is definitely of low quality, but is expected to have great resonance if measured in terms of altmetrics.

"Altmetrics and Grey Literature: Perspectives and Challenges"

Posted in E-Prints, Open Access, Scholarly Metrics, Self-Archiving on December 2nd, 2016

Joachim Schöpfel and Hêlêne Prost have self-archived "Altmetrics and Grey Literature: Perspectives and Challenges."

Here's an excerpt:

The topic of our paper is the connection between altmetrics and grey literature. Do altmetrics offer new opportunities for the development and impact of grey literature? In particular, the paper explores how altmetrics could add value to grey literature, in particular how reference managers, repositories, academic search engines and social networks can produce altmetrics of dissertations, reports, conference papers etc. We explore, too, how new altmetric tools incorporate grey literature as source for impact assessment, and if they do. The discussion analyses the potential but also the limits of the actual application of altmetrics to grey literatures and highlights the importance of unique identifiers, above all the DOI.

"Undercounting File Downloads from Institutional Repositories"

Posted in Digital Repositories, Institutional Repositories, Open Access, Scholarly Metrics, Self-Archiving on October 13th, 2016

Patrick Obrien et al. have published "Undercounting File Downloads from Institutional Repositories" in the Journal of Library Administration.

Here's an excerpt:

A primary impact metric for institutional repositories (IR) is the number of file downloads, which are commonly measured through third-party Web analytics software. Google Analytics, a free service used by most academic libraries, relies on HTML page tagging to log visitor activity on Google's servers. However, Web aggregators such as Google Scholar link directly to high value content (usually PDF files), bypassing the HTML page and failing to register these direct access events. This article presents evidence of a study of four institutions demonstrating that the majority of IR activity is not counted by page tagging Web analytics software, and proposes a practical solution for significantly improving the reporting relevancy and accuracy of IR performance metrics using Google Analytics.
