The General Impact Factor (GIF) and Universal Digital Object Information was founded by renowned scientist in 2012. A group of 65 scientist from various countries in different disciplines are started UDOI and GIF with specific objective of providing quality information to the researcher. General Impact Factor offering academic database services to researcher. Its mainly: citation indexing, analysis, and maintains citation databases covering thousands of academic journals, books, proceedings and any approved documents. All of these are available via UDOI's Web of Journal Knowledge database service. This database allows a researcher to identify which articles have been cited most frequently, who has cited them and find out the General Impact Factor (GIF). UDOI also publishes the annual Journal Reference Report which list an journal impact factor for each of the journals that it tracks. Within the scientific community, journal impact factors play a large but controversial role in determining journal impact factor to a published research record A list of over 100 journals is maintained by the GIF. The list includes engineering, management and science journals. Listing is based on published selection criteria and is an important indicator of journal quality and impact
The General Impact Factor is a measure of the frequency with which the "average article" in a journal has been cited in a given period of time. The Universal Impact Factor is calculated by several scientific methods. Authors and research scholars normally want to obtain quantitative measures of journals' quality and to know how different journals compared related to these measures.
The General Imfact Factor, a number calculated annually for each scientific journal based on the average number of times its articles have been referenced in other articles, in not intended to be used to evaluate individual scientists, but rather as a measure of journal quality. The impact factor is used to compare different journals within a certain field. The impact factor is highly discipline-dependent, due to the speed with which papers get cited in a field.
