In any given year, the impact factor of a journal is the average number of citations received per paper published in that journal during the two preceding years. For example, if a journal has an impact factor of 3 in 2008, then its papers published in 2006 and 2007 received 3 citations each on average in 2008. The 2008 impact factor of a journal would be calculated as follows:
2008 impact factor =A/B.
A = the number of times that all items published in that journal in 2006 and 2007 were cited by indexed publications during 2008.
B = the total number of "citable items" published by that journal in 2006 and 2007. ("Citable items" for this calculation are usually articles, reviews, proceedings, or notes; not editorials or letters to the editor).
(Note that 2008 impact factors are actually published in 2009; they cannot be calculated until all of the 2008 publications have been processed .)
New journals, which are indexed from their first published issue, will receive an impact factor after one year 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. Journals that are indexed starting with a volume other than the first volume will not get an impact factor until they have been indexed for three years. Occasionally, Thomson Routers assigns an impact factor to new journals with less than two years of indexing, based on partial citation data. Annuals and other irregular publications sometimes publish no items in a particular year, affecting the count. The impact factor relates to a specific time period; it is possible to calculate it for any desired period, and the Journal Citation Reports (JCR) also includes a five-year
The below quality factors are evaluated:
Originality Contribution (OC): 50%
Scientific Quality of Publication Contribution(SQC):20%
Manuscript Presentational Quality Contribution (RPC):20%
Regularity and stability Contribution(RSC):5%
Technical Editing Quality Contribution(TEQC):5%
There are many ways to produce new knowledge: observations, experiments, new approaches to solving existing problems, etc. An original research article is the one based on original research, and here it is needed to define what original research is all about which means that if the knowledge is used properly, it leads to innovation of new ideas or further enhancements, while on the other side when such knowledge is used repetitively in a reformulated fashion it would result in plagiarism of research articles pulling out the quality of research. In a few words, the research produces new knowledge instead of summarizing what is already known in a new form.
Article Originality : It is the important factor for getting Impact Factor. If Plagairism is detected in articles then the impact factor will be reduced.
Citation Counts : The no. of articles cited for respective year of that journal.
Journal Discipline : Discipline of the journal.
Journals Estimated Importance and Relevance of the Research Field.
The journal's presence in various indexing services, directories and listings.
The main and important factor is journal publishing regularity.
Management bodies for the journal governance - such as Editorial Board, Advisory Board, Executive Board, Article Review Team etc.
The International representation of research fellows in the Editorial Board boosts the score of the journal, and it creates a chance to further the journal's development.
Printing quality of journal Cover page [i.e. all the items should appear clearly: title, ISSN No. (Print / Online), frequency of the journal, current volume/issue/part number, month/year etc.]. And In case of print version, a hard copy should be sent for reviewing.
Journal website design. i.e. ease of use, ease of access, online submission, payment methods. In case of print only then quality of printed version of journal, regularity of article publishing, back issue viewing.
Using punctuation consistently.
Ensuring that there are no duplicate tables and figure titles
Checking hyperlinks to references.
Reviewing sentences for spelling and grammatical mistakes.
Checking style, size, and typeface for headings, titles, bullets etc.
Checking lists, paragraphs, figures, etc., numbered or lettered consecutively.
Choosing correct size and layout of pages.
Checking of Insertion of appropriate page breaks
Ensuring consistent justification for text, callouts, cautions, warnings etc.
Correct page numbers and spelling in the document.
Checking text and page numbers in table of contents.
Checking and Ensuring tables, figures, references, etc. cited in text
Ensuring consistent use of capitalization and spelling.
Applying proper numbering mechanics in the article.
Checking format for bibliographic references, i.e. according to any of Citation Style.
Degree of acceptance and presence of journal in the International and National market.
The important factor of editorial quality is the standard composition of presented article manuscripts and adherence to the journal's instructions for its authors. For example, the summary should count 200-250 words and have a structured form, i.e. standard structure of an article (background, material and methods used, results, conclusion).
References and Indices should be presented in proper sequencing order (as they are cited in the text). The first five authors should be presented.
The language of publication: English is preferred.
Online Internet publication and its constant maintenance.
The journal should include detailed editorial and author guidelines information regarding manuscript preparation.
The journal editorial data ought to embrace a listing of Editorial Board members, editorial correspondence addresses, the name and address of the publisher, ISSN and frequency of article publishing (monthly, quarterly, bi annual, annual etc).
Regularity is an important aspect . Each indexed journal should be publish regularly according to time frame of individual Journal . For Ex :- Monthly , Quarterly , Annually etc.
If the articles have the plagiarism issue and have been copied from the original article and for irregular/late publishing of the issues may lead negative scores also which will affect the TECF. The evaluation will be based on the decisions of the reviewers.
