The impact factor of a journal represents the influence of a journal based on its number of citations. It is used as a metric to show the relative significance of a journal with respect to its field. If the impact factor of a journal is high, it implies the relevance of the journal when compared to other ones. It was stated first by Eugene Garfield and now it is considered as a major factor to judge a journal.
Journals within an explicit authority are often judged according to their popularity and depth. The ranking technique often depends on the citation data and it is analyzed very carefully for accurate measures. It is actually considered as a relative measure and not considered as an individual value.
The factor is calculated based on a specific time period. Hence it is obvious that the impact factor 2012 will be actually calculated and published in 2013. To calculate the impact factor of 2012, first consider the number of proceedings or articles published during the period 2012-2011. That is,
Impact factor 2012 = Number of times the published articles of previous year were cited in journals during this year / The total number of articles published last year
It is used to classify journals according to its quality and impact. If the journals are cited often by other popular and influential journals, it is considered to be authoritative in that particular field.
Using the “author impact factor”, we can understand the scientific value of a given author or researcher. The actual impact and productivity of an author is defined in terms of the “h-index” value.

The Journal Citation Reports (JCR) is considered as a reliable measure in this field. It is published by Thomson Reuters and journals are thoroughly examined to check its quality and influence in its respective areas. It outlines the relationship between the journals that are cited as well as the citing journals so that the leading journals can be evaluated effectively.
