What Is  Impact Factors & Article Citations

    The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scient metric index that reflects the yearly average number of citations that articles published in the last two years in each journal received. It is frequently used as a proxy for the relative importance of a journal within its field; journals with higher impact factors are often deemed to be more important than those with lower ones.

History of Journals Data Base In Research

    The impact factor was devised by Eugene Garfield, the founder of the Institute for Scientific Information (ISI). Impact factors are calculated yearly starting from 1975 for journals listed in the Journal Citation Reports (JCR). 

    ISI was acquired by Thomson Scientific & Healthcare in 1992 and became known as Thomson ISI. In 2018, Thomson ISI was sold to Onex Corporation and Baring Private Equity Asia. They founded a new corporation, Clarivate, which is now the publisher of JCR.

    The value of impact factor depends on how to define “citations” and “publications”; the latter are often referred to as “citable items”. In current practice, both “citations” and “publications” are defined exclusively by ISI as follows. “Publications” are items that are classed as “article”, “review” or “proceedings paper” in the Web of Science (WoS) database; other items like editorials, corrections, notes, retractions, and discussions are excluded. 

    WoS is accessible to all registered users, who can independently verify the number of citable items for a given journal. In contrast, the number of citations is extracted not from the WoS database, but from a dedicated JCR database, which is not accessible to general readers. Hence, the commonly used “JCR Impact Factor” is a proprietary value, which is defined and calculated by ISI and cannot be verified by external users.

    New journals, which are indexed from their first published issue, will receive an impact factor after two years of indexing; in this case, the citations to the year prior to Volume 1, and the number of articles published in the year prior to Volume 1, are known zero values.

How is Impact Factor Calculated?

    The calculation is based on a two-year period and involves dividing the number of times articles were cited by the number of articles that are citable.

Calculation of 2010 IF of a Journal

A = the number of times articles published in 2008 and 2009 were cited by indexed journals during 2010.

B = the total number of “citable items” published in 2008 and 2009.

A/B = 2010 impact factor

What are Scientific Journals & HEC Journal Categorization? W, X, Y & Z Category.

    HEC has developed a mechanism in which they have categorized all the national and international journals into 4 categories. The journals are classified into W, X, Y, and Z category. The following are details of each category.

W Category

    Journals listed in Journal Citation Report (JCR) of ISI having an Impact Factor are categorized into W category. These are the most valued journals.

X Category

    Expert groups certify that they are top, recognized journals in the subject of archival quality. Journals not having an Impact Factor but verified by HEC that they meet all HEC Journal Criteria and have paper reviewed by at least one expert from an Industrially/Academically advanced country in the respective discipline.

Y Category

    Expert groups certify that they are top, recognized journals in the subject of archival quality. Journals not having an Impact Factor. They meet all HEC Journal Criteria except review of each paper by at least one expert from an Industrially/Academically advanced country in the respective discipline.

Z Category

    Expert groups certify that they are good, recognized journals in the subject of archival quality. Journals not having an Impact Factor. They meet all HEC Journal Criteria except Review of each paper by at least one expert from an Industrially/Academically advanced country in the respective Discipline and not Abstracted/Indexed internationally by a recognized Agency.

Utilization of Categories

W Category: Acceptable for Tenure Track System

X Category: Acceptable for BPS appointments/ promotions, HEC Approved Supervisor and Publication of research of PhD work until 30th June 2016. The Candidates enrolled in PhD after January 10, 2010 are required to publish their research paper in HEC recognized “W or X” category journals for award of PhD degree.

Y Category: Acceptable for BPS appointments and Publication of research of PhD work until June 30th, 2016. The candidates enrolled in PhD before January 11, 2010 can publish the research paper in HEC Recognized “Y” category journal for award of PhD degree

    The International Social Science Journals included in Journal Citation Report (JCR) of Institute for Scientific Information (ISI) would be considered as “W” category journals. Journals included in ISI Master List would be considered as “X” category journals. Journals abstracted/ indexed by the agencies mentioned in the Ulrich Periodical Directory would be considered as “Y” category journals. The International Science Journals having an impact factor and are listed in Journal Citation Report (JCR:
