What is an example of an impact factor?

For example, Nature had an impact factor of 41.577 in 2017: This means that, on average, its papers published in 2015 and 2016 received roughly 42 citations each in 2017. 2017 impact factors are reported in 2018; they cannot be calculated until all of the 2017 publications have been processed by the indexing agency.

What is considered an impact factor?

An impact factor measures the average number of a journal's citations in a two-year period. Ultimately, this measure calculates the rank of the journal in question. The more citations a journal has, the higher ranked it is.

What does an impact factor of 3.5 mean?

A journal impact factor is a metric that assesses the citation rate of articles published in a particular journal over a specific time – that's usually 2 years (see below). For example, an IF of 3 means that published articles have been cited on average 3 times during the previous 2 years.

How do I find my impact factor?

It's one of the most popular metric tools used for this purpose. However, what is a good impact factor? Technically, it depends on the subject category, but we can safely say that 10 is an excellent score in most fields.

Is an impact factor of 2 good?

Yes, 2.1 is considered a good impact factor. Impact factors can vary greatly depending on the field and journal, but generally, a score above 2.0 is considered to be in the top 25% of journals in that field. A score of 2.1 indicates that the journal is highly cited and influential within its field.

What is a good h-index?

What is a Good H-Index? Hirsch reckons that after 20 years of research, an h-index of 20 is good, 40 is outstanding, and 60 is truly exceptional. In his paper, Hirsch shows that successful scientists do, indeed, have high h-indices: 84% of Nobel Prize winners in physics, for example, had an h-index of at least 30.

What does the impact factor of a journal tell you?

Impact factor is commonly used to evaluate the relative importance of a journal within its field and to measure the frequency with which the “average article” in a journal has been cited in a particular time period. Journal which publishes more review articles will get highest IFs.

Is 0.2 a good impact factor?

Most journals (and there are many, many journals) have impact factors that are below 2. Journals with impact factors above 4 tend to be regarded as having a high impact factor, and those above 10 are stellar.

What does it mean if a journal has a low impact factor?

As a journal-level metric, it is frequently used as a proxy for the relative importance of a journal within its field; journals with higher impact factor values are given the status of being more important, or carry more prestige in their respective fields, than those with lower values.

What is a good h-index after 30 years?

h index of 60 after 20 years, or 90 after 30 years, characterizes truly unique individuals.

Is impact factor 10 good?

Both these measures are variations of "average citations received per article", but they are computed on a slightly different database and so they give different results.

How long does it take for a journal to get a impact factor?

Once it is accepted for coverage it usually receives its first impact factor only three years later. However, being selected for coverage is not an easy task. Each year, Thomson Reuters editorial staff reviews over 2,000 journals and only around 10-12% of them are accepted for coverage.

What makes a good journal?

Transparency from the journal as to its aim and scope, the editorial board, indexing status, the peer review process, reputation, and policies for authors are among the key indicators of quality journals. These criteria can help identify quality journals suitable for publication.

What is the difference between impact factor and H factor?

Journal impact factor (which reflects a particular journal's quality) and H index (which reflects the number and quality of an author's publications) are two measures of research quality. It has been argued that the H index outperforms the impact factor for evaluation purposes.
