The Impact Factor is a measure of the frequency in which the "average article" from a particular journal has been cited in a given period of time. It is one way scholars measure the relative importance of a journal within its field.
Use InCites Journal Citation Reports (JCR) to locate Journal Impact Factors and JIF quartile rankings.
Journal Quartile Rankings
Journal quartile rankings are calculated by the JIF of the journal and dividing it by the number journals in that category to find x. They are then distributed among as follows:
Q1: 0.0 < x ≤ 0.25
Q2: 0.25 < x ≤ 0.5
Q3: 0.5 < x ≤ 0.75
Q4: 0.75 <x
When searching in Web of Science, hover over the journal title in the results list or item record to view the journal's quartile ranking

Web of Science provides the total number of times a published work was cited by other works. The Times Cited view sorts results so that items with the highest numbers of citations are at the top of the results list.
In addition, Web of Science provides filters to limit results to Highly Cited and Hot Papers.
Highly Cited Papers are papers that perform in the top 1% based on the number of citations received when compared to other papers published in the same field in the same year.
Hot Papers are papers published in the last two years that are receiving citations quickly after publication. These papers have been cited enough times in the most recent bimonthly period to place them in the top 0.1% when compared to papers in the same field.
