What is the Eigenfactor score?

The Eigenfactor Score measures a journal's total importance to the scientific community, calculated from weighted citations over five years, excluding self-citations, and normalized so all scores total 100. It's similar to Google's PageRank, giving more weight to citations from prestigious journals, and unlike the Impact Factor, it accounts for journal size, meaning larger journals naturally have higher scores, but it also offers the Article Influence Score (AI) to show average article influence (AI > 1.00 means above-average influence).

What is a good eigenfactor score?

That fraction is normalized so that the sum total of articles from all journals is 1. The mean Article Influence Score is 1.00. A score greater than 1.00 indicates that each article in the journal has above-average influence. A score less than 1.00 indicates that each article in the journal has below-average influence.

What does a journal has a normalized eigenfactor score of 3 mean?

The Normalized Eigenfactor Score rescales the Eigenfactor Score so that the average journal has a score of 1. This makes the scores easier to read and interpret: for example, a journal with a Normalized Eigenfactor Score of 3 has three times the total influence of the average journal.

What is the eigenfactor percentile?

Eigenfactor scores are scaled so that the Eigenfactor scores of all journals listed in Thomson's Journal Citation Reports (JCR) sum to 100. Thus if a journal has an Eigenfactor score of 1.0, it has 1% of the total influence of all indexed publications.

Is 2.5 a high impact factor?

Yes, a 2.5 Impact Factor (IF) is generally considered a good score, especially in fields like social sciences or physical sciences, though "high impact" varies significantly by discipline; while STEM fields might see 10+ as high, 2-5 is often solid in social sciences, and a 2.5 means papers are cited 2.5 times on average in the past two years, making it respectable and above the overall average.

Is 0.6 a good impact factor?

The new impact factor of 0.6 represents a significant step forward for Health Scope and demonstrates the increasing relevance and impact of the research published in our journal.

How is eigen factor score different from impact factor?

Eigenfactor scores are similar to impact factor, but excludes self-citations, removing one way to manipulate scores. Eigenfactor is similar to Impact factor in that it provides a number for a journal, ranking it within a category.

Is an impact score of 30 good?

Impact scores run from 10 to 90, where 10 is best. Generally speaking, impact/priority scores of 10 to 30 are most likely to be funded; scores between 31 and 45 might be funded; scores greater than 46 are rarely funded.

Which is better, Scopus or scimago?

Most funding bodies rely only on Scopus. Scimago is a supporting tool: The Scimago Journal Rank (SJR) platform was created for analytics and easy navigation. Yes, it also uses Scopus data, but recalculates them using its own formula, updates with a delay, and may display a different quartile than Scopus.

Is 7.1 a good impact factor?

Is 12 impact factor high?

Only a tiny fraction - 144 journals (less than 1%) - achieved an impact factor of 20 or above. Expanding to journals with impact factors of 10 or higher was still only about 2.3% of all journals. Overall, very high impact factors are quite rare, with most journals having impact factors below 2.

What does an impact factor of 1.9 mean?

A Journal Impact Factor of 1.9 means that each article from 2020 and 2019 was cited an average of 1.9 times in 2021. But since the JIF is based on only a certain percentage of the articles that actually appeared, this method of taking the arithmetic mean is actually statistically inappropriate.

Is 8.5 a good impact factor?

Impact Factor Range

Between 3 and 10 - Good to very good, depending on the specific field. Between 1 and 3 - Average but respectable in many fields. Below 1 - Generally low but acceptable for niche or emerging fields.

Is 3.7 a high impact factor?

Yes, a 3.7 impact factor is generally considered a good to very good score, representing a reputable journal, though "high" depends heavily on the specific academic field; it's well above the < 1 average and strong in many areas like social sciences, but might be considered moderate in extremely competitive fields like top-tier medicine where factors above 10 are common. 

Can impact factor be manipulated?

However, impact factors may be manipulated by editors. According to the ex- planatory statements and announcements made by the authors submitting their work to the journals, the impact factor is still being di- rectly manipulated [4–6].
