Submit your Journal to get IARC-JCRR Indexing and Impact Factor

Impact Factor calculated by IARC on the basis of Journal Citation Reference (JCR) Report.


Evaluation Methodology

IARC was established by a group of renowned researchers, scientists, engineers and academicians having multi geographical representations with an objective of providing quality metrics and journal analytics to the researcher. Impact factors are calculated yearly for those journals that are indexed in 'International Accreditation and Research Council' 'Journal Citation Reference Reports' (JCRR). JCRR provides quantitative tools for evaluating, categorizing and comparing journals. The IF is a measure of average number of citations and reference to the articles published in arts, agriculture and forestry sciences, animal, veterinary and fishery sciences, biological sciences, chemical sciences, computer and information technology sciences, earth sciences, engineering sciences (civil, cybernetics electrical, electronics, mechanical, textile), environmental sciences, forensic sciences, family, community and consumer sciences, home sciences, humanity sciences, library sciences, material sciences mathematical and statistical sciences, medical sciences, military sciences, pharmaceutical sciences, physical sciences, physical education sciences, educational sciences: for school students, women, village and society, commerce, law and management related with sciences, anthropological and behavioral sciences: sociology, social sciences: researches in the field of economics, political science, geography, drawing, music, dance, philosophy, history and languages concerning with science, journalism and role of media in science, role of NGOs in the protection of environment journals.

IARC-IF is a measure reflecting the average number of citations to articles published in journals, books, patent document, thesis, project reports, newspapers, conference/ seminar proceedings, documents published in internet, notes and any other approved document. It is a measure of the frequency with which the average article in a journal has been cited in a given period of time. The annual JCRR impact factor is a ratio between citations, reference and recent citable items published. The impact factor for a journal is calculated on the basis of a three-year period and can be considered to be the average number of times published papers are cited and its articles have been referenced in other articles up-to two years after publication. Also IARC calculated based on governance and commercial quality, scientific quality, editorial quality, international presence and Infrastructure, Stability, Standards, Contextual citation. In general high impact factor journals are recognized as the most influential as compared to the other journals published in the same field. The IF is used to compare different journals within a certain field. The 'International Accreditation and Research Council' indexes many Arts, Agriculture, Science, Computer Science, Engineering, Information Technology, Commerce, Management, Economics Sociology and Social Science journals. Those journals are indexed in Journal Citation Reference Reports (JCRR).
Evaluation Methodology
A) Calculation of yearly impact factor based on three year period.
  1. 1. X=Total cites in 2009
  2. 2. Y= 2009 cites to articles published in 2007-08 (This is subset of X)
  3. 3. Z= Number of articles published in 2007-08
  4. 4. IF=Y/Z=2009 impact factor
Actual Calculation of impact factor in 2009
    Cites in 2009 to articles published in:
    2008 = 456
    2007 = 468
    Total = 924

Number of articles published in:
    2008 = 80
    2007 = 74
    Total = 154
Impact factor = cites to recent articles/number of recent articles = 924/154=6.0

B) Calculation of five year impact factor
  1. 1. X= Citations in 2011 over the 2006-2010
  2. 2. Y= Articles published over the years 2006-2010
  3. 3. Z= X/Y = Five year impact factor (Source: Web of Knowledge)
The impact factor is useful in clarifying the significance of absolute citation frequencies. It eliminates some of the bias of such counts which favor large journals over small ones, or frequently issued journals over less frequently issued ones, and of older journals over newer ones. Particularly in the latter case such journals have a larger citable body of literature than smaller or younger journals. All things being equal, the larger the number of previously published articles, the more often a journal will be cited.

There have been many innovative applications of journal impact factors.
1. It is important for market research for publishers and others.
2. This is an important tool for librarians, researchers and for the librarians.
3. It is also an important tool for researcher to select a reputed journal and publish in elderly and reputed journals.
4. The impact factor can be used to provide a gross approximation about the prestige of a journal. 5. It is also a tool for sensible use and quote of data with proper care in the journals.
In general authors should keep in mind that
1. Impact factor can be calculated after completing the minimum of 3 years of publication.
2. Journal Impact Factor will be a quotient factor only and will not be a quality factor.
3. Journal Impact Factor will not be related to quality of content and quality of peer review.
4. Journal which publishes more review articles will get highest impact factors.
5. The impact factor is highly discipline dependent.
6. The impact factor could not be reproduced in an independent audit.
7. The impact factor refers to the average number of citations per paper.
8. Counting citations may be independent of the real 'impact' of the work among investigators and scientific communities.
9. Self-citations and purposeful addition of the same journal article with the favorable editorial policies may cause the journals or publishers to be not considered for the evaluation of the impact factor.
10. The IF may be incorrectly applied to evaluate the significance of an individual publication or to evaluate an individual researcher.
11. A title change affects the impact factor for two years after a change is made. The old and new titles are not unified unless the titles are in the same position alphabetically.

Advantages of Impact Factor (IARC)
There are many advantages of journal citation impact factors. The most common one involves market research for publishers and others. But, primarily, IARC provides librarians, scientists and researchers with a tool for the management of library journal collections. In market research, the impact factor provides quantitative evidence for editors and publishers for positioning their journals in relation to the competition especially others in the same subject category, in a vertical rather than a horizontal or interdisciplinary comparison. As a tool for management of library journal collections, the impact factor supplies the library administrator with information about journals already in the collection and journals under consideration for acquisition. These data must also be combined with cost and circulation data to make rational decisions about purchases of journals. Perhaps the most important and recent use of impact factor is in the process of academic evaluation. The impact factor can be used to provide a gross approximation of the prestige of journals in which individuals have been published. This is best done in consideration with other considerations such as peer review, productivity, and subject specialty citation rates. The impact factor can be useful in all of these applications, provided the data are used sensibly. It is important to note that qualitative methods can be used in evaluating journals such as interviews, questionnaires, schedules etc. In general, there is good agreement on the relative value of journals in the appropriate categories. However, the IARC makes possible the realization that many journals do not fit easily into established categories.

IARC does not recommend the 'IARC Impact Factor' as the only important metrics for assessing the usefulness of a journal. Rather IARC does not depend on the impact factor alone in assessing the usefulness of a journal. The impact factor should not be used without careful attention to the many phenomena that influence citation rates, as the average number of references cited in the average article. In the case of academic evaluation for tenure it is sometimes inappropriate to use the impact of the source journal to estimate the expected frequency of a recently published article. Again, the impact factor should be used with informed peer review. Citation frequencies for individual articles are quite varied.
