What is the meaning of CiteScore?
CiteScore is the number of citations received by a journal in one year to documents published in the three previous years, divided by the number of documents indexed in Scopus published in those same three years.
What is a good Eigenfactor?
A score greater than 1.00 indicates that each article in the journal has above-average influence. A score less than 1.00 indicates that each article in the journal has below-average influence. Article Influence uses Thomson Reuters Web of Science citation data.
How do you calculate Eigenfactor?
The Eigenfactor calculation is based on the number of times articles from the journal published in the past five years have been cited in the JCR year, but it also considers which journals have contributed these citations so that highly cited journals will influence the network more than lesser cited journals.
What is normalized Eigenfactor?
The Normalized Eigenfactor Score is the Eigenfactor score normalized, by rescaling the total number of journals in the JCR each year, so that the average journal has a score of 1. Journals can then be compared and influence measured by their score relative to 1.
What is Scopus score?
Scopus is citation database that gives quality measure for each title while impact factor reflects the yearly average number of citation of articles published in the last two years in a given journal. Impact factor is calculated based on the number of papers published and cited.
What is Scopus CiteScore?
CiteScore is another metric for measuring journal impact in Scopus. The calculation of CiteScore for the current year is based on the number of citations received by a journal in the latest 4 years (including the calculation year), divided by the number of documents published in the journal in those four years.
What is i10 index in Google Scholar?
i10-Index = the number of publications with at least 10 citations. This very simple measure is only used by Google Scholar, and is another way to help gauge the productivity of a scholar.
How do you find the Eigenfactor of a journal?
To find a journal’s Eigenfactor, Article Influence, or Normalized Eigenfactor score, go to the Journal Ranking Search page on the Eigenfactor website. From the Journal Ranking search page, you can search for a journal name, ISSN, publisher, year, ISI category or exact journal name.
What is snip of a journal?
Source-normalized Impact per Paper (SNIP) is a field normalised assessment of journal impact. SNIP scores are the ratio of a source’s average citation count and ‘citation potential’. A journal with a SNIP of 1.0 has the median (not mean) number of citations for journals in that field.
What is JCR database?
Journal Citation Reports (or JCR) is a product of ISI Web of Knowledge and is an authoratative resource for impact factor data. This database provides impact factors and rankings of many journals in the social and life sciences based on millions of citations.
What is a high impact paper?
High impact journals seek high quality manuscripts that not only contribute to the knowledge of the reader but also clearly communicate the results and impact of the research.
Is Scopus a good journal?
Scopus is the largest abstract and citation database of peer-reviewed research literature, introduced by Elsevier in the year 2004. Several research scholars consider it as a high quality source for contemporary data analyses as it includes almost all the science journals covered under WOS.
What do you need to know about the Eigenfactor score?
Eigenfactor. The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to…
How is the Eigenfactor of a journal calculated?
Although the calculation is complicated, a journal eigenfactor is basically a measure of how many people read a journal and think its contents are important. Since this cannot be directly calculated, it is measured by counting the total number of citations a journal receives over a five-year period.
Which is more robust impact factor or Eigenfactor?
The Article Influence score measures the average influence of articles in the journal, and is therefore comparable to the traditional impact factor . The Eigenfactor approach is thought to be more robust than the impact factor metric, which purely counts incoming citations without considering the significance of those citations.
How are eigenvalues and eigenvectors related to each other?
Eigenvalues and eigenvectors give rise to many closely related mathematical concepts, and the prefix eigen- is applied liberally when naming them: The set of all eigenvectors of a linear transformation, each paired with its corresponding eigenvalue, is called the eigensystem of that transformation.
