What is a good SJR for a journal?

The scoring scale brings everything down to 1 for easy comparison. So a journal with a SJR value >1 has above average citation potential and journal with a SJR value <1.

What is H index and SJR?

See detailed description of SJR (PDF). H Index The h index expresses the journal’s number of articles (h) that have received at least h citations. It quantifies both journal scientific productivity and scientific impact and it is also applicable to scientists, countries, etc. (

What is the difference between SJR and JCR?

One of the most important differences between SJR and JCR is the access that they provide: JCR is a paid-for tool which is accessed via the Web Of Science platform. The database of citations on which it is supported – the Web Of Science Core Collection – is also a paid-for service. SJR is free of charge.

What is Q1 Q2 Q3/Q4 journal?

Each subject category of journals is divided into four quartiles: Q1, Q2, Q3, Q4. Q1 is occupied by the top 25% of journals in the list; Q2 is occupied by journals in the 25 to 50% group; Q3 is occupied by journals in the 50 to 75% group and Q4 is occupied by journals in the 75 to 100% group.

What is a good SJR rank?

A SNIP of 1.0 means that a journal’s articles are cited at the average rate for all journals in the same subject area; anything over 1.0 indicates more citations than average in the field while a SNIP of less than 1.0 is below the average. A SNIP of more than 1.5 generally indicates a very well-cited journal.

Is an h-index of 20 good?

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.

Do journals have h-index?

Journal h-index is one measure of the quality of a journal and can be calculated using data from Web of Science, Scopus or Google Scholar.

What is a high SJR score?

Higher SJR values are meant to indicate greater journal prestige. The SJR indicator is a free journal metric inspired by, and using an algorithm similar to, PageRank. The SJR indicator provides an alternative to the impact factor (IF) or average citations per document in a 2-year period, abbreviated as “Cites per Doc.

What are Q journals?

Q index defines the rank of a journal in a specific field. It describes ranking of the journal as as Q1, Q2, Q3, and Q4 where Q1 means the ranking among top 25% journals in the same field.

Is 2.8 a good impact factor?

In most fields, the impact factor of 10 or greater is considered an excellent score while 3 is flagged as good and the average score is less than 1. The impact factor is a subjective matter and has the most meaning only when comparing journals within similar fields.

What does SJR mean in terms of citations?

It expresses the average number of weighted citations received in the selected year by the documents published in the selected journal in the three previous years, –i.e. weighted citations received in year X to documents published in the journal in years X-1, X-2 and X-3. See detailed description of SJR

What does SJR mean in SCImago Journal Rank?

SJR(SCImago Journal Rank) indicator It expresses the average number of weighted citations received in the selected year by the documents published in the selected journal in the three previous years, –i.e. weighted citations received in year X to documents published in the journal in years X-1, X-2 and X-3.

What does a high SJR mean for a journal?

Higher SJR values are meant to indicate greater journal prestige. The SJR indicator is a variant of the eigenvector centrality measure used in network theory. Such measures establish the importance of a node in a network based on the principle that connections to high-scoring nodes contribute more to the score of the node.

How does the SJR algorithm work for a journal?

The SJR algorithm begins by setting an identical amount of prestige to each journal, then using an iterative procedure, this prestige is redistributed in a process where journals transfer their achieved prestige to each other through citations.
