Impact factor

Impact factor (Impact factor, abbreviation IF) refers to the frequency with which articles of a certain journal are cited in a specific year or period.
It is an important indicator of the influence of academic journals .
It was originally developed by the founder of the Institute of Scientific Information (ISI).
Eugene Garfield was founded in the 1960s and has since brought a series of major innovations to the development of bibliometrics
.

Since 1975, it has been regularly published every year in the "Journal Citation Reports" (Journal Citation Reports)

Impact factor (Impact factor, abbreviated IF) refers to the frequency with which articles of a certain journal are cited in a specific year or period, and is an important indicator to measure the influence of academic journals.

Eugene Garfield (1925–2017) 

Eugene Garfield was one of the most influential figures in library and information science in the second half of the 20th century
.

He created a citation index in scientific and academic journal literature, which records the references cited in each article and serves as the link between the papers, creating a network of ideas and concepts that can be navigated back and forth in time

In recent years, Cite Score and H Index have begun to rise, but they still cannot shake the status of IF

Although the impact factor is only announced in mid-to-late June each year, before the announcement, Metz Medical makes some predictions in advance.
This article estimates the data based on WOS with high accuracy
.

However, in fact, most of the data in the JCR report has been completed around February each year.

This article estimates the data based on WOS, with high accuracy

Therefore, our data may be slightly higher than the impact factor data published in the JCR report

According to the forecast and analysis of Metz, the top five journals in the field of gastroenterology published last year are still in the forefront this year, and the impact factor of Nature Reviews Gastroenterology & Hepatology has risen and remains at the top of the list
.

The Impact Factor of JOURNAL OF HEPATOLOGY dropped slightly, but it still remains in second place!
