Impact factor

Measure used in scientific journals that consists in the sum of relative weights of the factors within the wild card that forms the framework for the wild card equation. Calculation It is calculated based on a three-year period. For example, the 2003 impact factor for a journal would be calculated as follows: A = the number of times articles published in it in 2001-2 were cited in indexed journals during 2003. B = the number of articles, reviews, proceedings or notes published in 2001-2. 2003 impact factor = A/B Favorable properties of the impact factor include: Wide international coverage and that the results are publicly and freely available to use and understand. On the other hand, a longer temporal window would be slow to adjust to trend changes. The most commonly mentioned faults of the impact factor include: Number of citations does not really measure quality of publication, but also quantity of publication. The Impact Factor denominator adjusts for this quantity. The temporal window for citation is too short. The nature of results in different research areas yields different amounts of publications and at different paces, which has an effect on impact factors. Generally, for example, medical journals have higher impact factors than mathematical journals. By merely counting the frequency of citations per article and disregarding the prestige of the citing journals, the ISI IF is a metric of popularity, not of prestige.
