Check Impact Index of thousands of worldwide Journals
It is proposed by the founder of the Institute for Scientific Information, Eugene Eli Garfield and is being regularly calculated beginning from 1975 for all the journals registered in the
Journal Citation Reports (JCR).
For a given year, the Journal's IF is computed as the number of cites, received in that throughout the year, of the scientific articles or papers published in that particular journal during the two previous years,
dividing it by the number of articles published in that journal in the previous two years.years.
It helps to measure the relative importance of journals within particular areas and to compare the journals within the same areas. The higher the JIF, the better it is ranked. Typically, journals with more review articles or papers are able to achieve higher JIF.
The calculation of IF is based on a period of two years and computes as dividing the number of times articles published in that journal were cited by the total number of articles which are citable.
$IF_x = \frac{Citations_{x-1} + Citations_{x-2}}{Publications_{x-1} + Publications_{x-2}}$
For an example, to find the impact factor of a "ABC" journal for the year 2019, we would compute:
For example, if the Journal have the following citations and publications value:
Citations2018 = 80
Citations2017 = 60
Publications2018 = 30
Publications2017 = 40
IF2016= (80 + 60) / (30 + 40) = 2
This value of IF indicates that, on an average, the articles of "ABC" Journal published in the years 2017 and 2018 have approximately received 2 (two) citations each in the year of 2019.
It is important to note here that the 2018's IF is published in the year 2019. It cannot be computed until all publications in the previous year of 2018 are processed by the indexing agency.
To search the impact factor of any Journal or Conference, you can query by its title or ISSN. You can also query using the publisher name or by subject category in the search box and can select the required journal.
You can also check in detail analysis (like five years average, highest impact in the last five years, etc.) of a particular item, by clicking on the same.
Impact factor gives the approximate idea about how prestigious a particular journal is in its field.
The higher the IF of the journal, the better it is ranked. By using this metric you can basically evaluate and compare the journals in similar subject categories to identify their importance.
We perform various analysis on the data produced by SCImago.
The SCImago Journal & Country Rank is an openly accessible portal which covers the journals and scientific indicators generated from the data present in the Scopus® database (Elsevier B.V.).
Scopus database includes the information of more than 15,000 journals from different fields from around 4,000 publishers and also covers around 1000 open access journals
We perform statistical impact analysis for various journals and conference to evaluate their impact trends. You can find here the average impact index for the last three and five years. We also present here the highest (best) and lowest (worst) impact for the last few years. To show the variation of impact data over years, we compute and show the standard deviation.
The above metrics help you to better correlate and judge the impact of any particular journal/conference. We perform all the analysis on Cites/Doc. (2 Year) metric. Also known as impact index.
We cover the impact and detailed analysis of almost all the major areas and disciplines. We covered the following categories:
Endocrinology, Diabetes and Metabolism Environmental Chemistry Geology Otorhinolaryngology Small Animals Oncology (nursing) Pharmacy Pediatrics Ecology, Evolution, Behavior and Systematics Neuropsychology and Physiological Psychology Management of Technology and Innovation Pulmonary and Respiratory Medicine Mathematics (miscellaneous) Emergency Nursing Public Administration Complementary and Manual Therapy Computer Vision and Pattern Recognition Pharmaceutical Science Gerontology Health Professions (miscellaneous)
So far, we have covered our impact factor analysis for the years 2018, 2017, 2016, 2015, 2014, and 2013. However, we will update soon all our analysis for the year 2019 also, once the data is available.
We also provide the expert suggestions for top journals and conferences which are in related fields or in same categories. This will help you to find out other top journals and conference opportunities where you can submit your research paper or article to showcase the quality of your work.
It is always advised to submit your articles into a journal with high impact factor in your field. This is to show the credibility and worthiness of your research articles and your work.
It is observed that most of the reviewers judge the quality of your articles based on the referenced journal articles. Therefore, it is always recommended to cite or refer the articles from the top journals (Which are basically the one having high impact factor)
