Scientometrics are an approach to measure and analyse different aspects of science. While the term ‘scientometrics’ is often used interchangeably with ‘citation analysis’, other methods to evaluate science and its impact have been developed. Below, you will find some of the most commonly used traditional and non-traditional scientometrics.
ISI Web of Science
ISI Web of Science provides quick, powerful access to the world's leading citation databases. The multidisciplinary content covers over 12,000 of the highest impact journals worldwide, including Open Access journals and over 150,000 conference proceedings.
Google Scholar provides a simple way to broadly search for scholarly literature. From one place, you can search across many disciplines and sources: articles, theses, books, abstracts and court opinions, from academic publishers, professional societies, online repositories, universities and other web sites. Google Scholar helps you find relevant work across the world of scholarly research.
Scopus is the largest abstract and citation database of peer-reviewed literature: scientific journals, books and conference proceedings.
A platform for researchers that can be used to share research, discover and request others’ research and to get in touch with other researchers. All researchers registered on ResearchGate (RG) receive a RG Score, a metric for scientific reputation. The RG Score is based on how fellow researchers evaluate your contributions, and on their reputation.
Harzing's Publish or Perish
The website provides resources to assist with academic publishing and the assessment of research and journal quality, as well as software to conduct citation analysis.
An interactive platform independent browser extension that provides a smart interface for Google Scholar, which empowers non-experts to submit complex queries and maintains their history, allowing filtering, sorting, deleting and live search to compute error free impact measures.
Thomson Reuters Journal Citation Reports
Thomson Reuters Journal Citation Reports offers a systematic, objective means to critically evaluate the world's leading journals, with quantifiable, statistical information based on citation data. By compiling articles' cited references, JCR Web helps to measure research influence and impact at the journal and category levels, and shows the relationship between citing and cited journals.
Thomson Reuters Impact Factor was originally published in 1994.
Altmetrics are non-traditional metrics, that are complementary to the traditional citiation-based metrics. Examples of altmetrics are the number of blogs, news outlets or tweeters that mention a paper, or the number of readers on Mendeley. They are meant to reflect attention, dissemination, influence and impact of research. Ideally, altmetrics would capture a more diverse impact compared to traditional metrics. However, altmetrics also have several limitations. They are meant as a complement, not a replacement, of traditional metrics.
The Eigenfactor score is a measure of a journal’s total importance to the scientific community. The algorithms behind the Eigenfactor score rate the importance of a journal by using the structure of the entire research network (formed by citations and references between all journals), and not just the citations received to articles published in a journal. Other differences compared to the impact factor are the time period (5-year) and the ability for the Eigenfactor algorithms to adjust for citation differences across disciplines. For ease of use, a normalized score (Normalized Eigenfactor) is also reported; Normalized Eigenfactor scores above 1 reflect above-average influence. The Eigenfactorizer is a free plugin for the Google Chrome browser that color-codes PubMed search results according to Eigenfactor score.
Toolkit for the impact of Digitised Scholarly Resources
This toolkit was originally developed by the Oxford Internet Institute in 2008 to explore the questions: are digital resources succeeding at reaching their intended users? Are they having an impact on their community of users? How can impact be measured?
