Scimago journal rankings

SJR: SCImago Journal & Country Rank is a free portal with journal rankings by subject and country. Its ranks journals according to the SCImago Journal Rank ( SJR) indicator, which calculates journal influence by looking at both the number of citations received by a journal and the importance of the journal where the citation was published.

It also offers other metrics, such as the H index, citations per document, references per document, and more. Journals can be analyzed by broad subject area, narrow subject category, or by country. The journals and country data in SJR are drawn from the Scopus database. Citation data is drawn from over 34,000 titles from more than 5,000 international publishers.

Country performance metrics cover over 230 countries worldwide. The project is maintained by SCImago, a research group at the Consejo Superior de Investigaciones Científicas (CSIC), University of Granada, Extremadura, Carlos III (Madrid) and Alcalá de Henares.

The SCImago Journal & Country Rank is a publicly available portal that includes the journals and country scientific indicators developed from the information contained in the Scopus® database ( Scimago journal rankings B.V.).

These indicators can be used to assess and analyze scientific domains.

Journals can be compared or analysed separately. Country rankings may also be compared or analysed separately. Journals can be grouped by subject area (27 major thematic areas), subject category (313 specific subject categories) or by country. Citation data is drawn from over 34,100 titles from more than 5,000 international publishers and country performance metrics from 239 countries worldwide. The SJCR allows you also to embed significative journal metrics into your web as a clickable image widget This platform takes its name from the SCImago Journal Rank (SJR) indicator (PDF), developed by SCImago from the widely known algorithm Google PageRank™.

This indicator shows the visibility of the journals contained in the Scopus® database from 1996. SCImago is a research group from the Consejo Superior de Investigaciones Científicas scimago journal rankings, University of Granada, Extremadura, Carlos III (Madrid) and Alcalá de Henares, dedicated to information analysis, representation and retrieval by means of visualisation techniques.

As well as the SJR Portal, SCImago has developed The Shape of Science, the SIR (SCImago Institution Rankings) and the Atlas of Science. The Shape of Science is an information visualization project whose aim is to reveal the structure of science. Its interface has been designed to access the bibliometric indicators database of the SCImago Journal & Country Rank portal.The SIR is a classification of academic and research-related institutions ranked by a scimago journal rankings indicator that combines three different sets of indicators based on research performance, innovation outputs and societal impact measured by their web visibility.

The Atlas of Science project proposes the creation of an information system whose major aim is to achieve a graphic representation of IberoAmerican Science Research. Such representation is conceived as a collection of interactive maps, allowing scimago journal rankings functions throughout the semantic spaces formed by the maps.

Q1 to Q4 refer to journal ranking quartiles within a subdiscipline using the SJR citation index. Thus, a first quartile journal (i.e., Q1) has an SJR in the top 25% of journals for at least one of its classified subdisciplines. What is SJR? The SJR is an index of weighted citations per article over a period of three years ( https://www.scimagojr.com/aboutus.php ).

As far as citation based indicators of prestige go it is quite good. Citations and documents applied in this formula are based on the Scopus database. SCImago Journal Rank is a measure of scientific influence of scholarly journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from.

(Wikipedia) How is ranking done?

As noted, rankings are done at the subcategory/subdiscipline level. So for example, journals are not ranked at the level of "psychology" or "chemistry". Rather they are ranked at the level of "analytical chemistry" or "clinical psychology".

Note also that journals are often categorised in multiple subdisciplines, and the quartile can, and often does, vary based on the subdisscipline. The badge shown on scimago seems to take the most favourable ranking. So, for example, if the journal is ranked in the top quartile for at least one, it will have a badge as a Q1 journal. Critical commentary: In general, I think subdiscipline ranking based on SJR is superior to impact factors. It overcomes several biases in impact factor: • It uses a 3 year document window (impact factor uses 2): This is a better window across a broader range of disciplines.

• It weights citations by prestige which can reduce the capacity for gaming and aligns within common sense that not all citations are created equally. I believe this also incorporates the idea that each publication only has so much prestige to give, so a citation from a paper with 100 references is worth less than a citation with 20 references.

scimago journal rankings It uses scimago journal rankings more inclusive database of articles (i.e., Scopus) compared to Impact Factor which uses Web of Science.

• Even after controlling for many of the above factors, differences in citation practices exist between disciplines, so within sub-discipline rankings are often fairer. Furthermore, often researchers and evaluators are trying to make decisions like where to send their best work or how to evaluate the quality of work of a researcher who operates in a particular subdiscipline.

In this case, SJR within subdiscipline can be particularly useful. You can read all about their formula here. Q1 presumably means "first quartile." Currently, if you mouse-over the icon for best journal it says "first quartile." This is presumably a bug though. I couldn't find documentation on the meaning of Q1, Q2, etc. but the guess that it means "first, second etc. quartile in the ranking" seems to be correct. When you look at one of the "widgets" they have for scimago journal rankings journal, it says "quartile": BTW, whether the journal is in the first, second, third, or fourth quartile, the widget will (erroneously) always say "best quartile".

This doesn't change the conclusion that Q means quartile, however. • Home • Author Level Metrics Toggle Dropdown • H-index • Publication Counts • Article Level Metrics Toggle Dropdown • Citation Counts • Altmetrics • Field Normalized Citation Metrics scimago journal rankings Journal Level Metrics • Journal Impact Factor (JIF) • SCImago Journal Rank (SJR) • Eigenfactor Score • Keeping Up to Date The SJR (or, more specifically, the SJR2, which is the newer version of the SJR) is calculated by taking the weighted number of citations in a given year to citable publications published in the journal within the 3 preceding years, divided by the total number of citable publications published in the journal within the 3 preceding years.

Citations from publications published in more prestigious journals will receive greater weight than those from less prestigious journals, with "prestige" value being dependent on field. The SJR additionally takes into account journal "closeness" via co-citation networks, with citations from "closer" journals receiving greater weight.

For additional information on how the SJR is calculated, see Guerrero-Bote and Moya-Anegón's 2012 article. Note: SJRs will be based only on citing publications in Scopus (i.e., citations from publications that are not indexed in Scopus will not be factored into SJRs). SJRs are unique to SCImago and Scopus. You can access JCRs in either of these two sources (with SCImago being publicly accessible).

Finding a journal's SJR in Scopus • Go to Scopus • Click "Sources" towards the top of the page • The default will allow you to search by subject area. If you would like to search by title, click the dropdown in the upper left-hand corner of the page • From the dropdown, click "Title" • Enter the name of the journal into the search bar • Look for the journal in your results • Click the title of the journal • The SJR will display in the upper right-hand corner of the page Finding a journal's SJR in SCImago You can access SJRs in one of two ways in SCImago.

One method is to: scimago journal rankings Go to SCImago • Enter the journal's title into the search bar in the upper right-hand corner of the page • Look for the journal in the results list • Click the journal name • Scroll down until you see a graph labeled SJR. Hover you mouse over different sections of the graph to see the SJR for that specific time period. Alternatively, you can click the table view in the upper right-hand corner of the graph If you would like to see how your journal ranks with other journals in your field: • Go to SCImago • Click "All Subject Areas" to select a subject area • If you would like to narrow your subject further, click "All Subject Categories" to select a subject category • Look for the journal in the results list • The SJR will display in the third column from the left Like any impact metric, SJRs have their limitations.

Some of these limitations include: • May be skewed by citation outliers (e.g., a single article may receive the vast majority of citations) • May penalize interdisciplinary works (i.e., citations from within the journal's co-citation network are weighted higher than those scimago journal rankings journals outside of the co-citation network) • Not all citations are "good" citations (e.g., Article A may cite Article B to reject Article B's findings) • A "good" SJR differs by field • Includes some self-citation (but have a percentage cap, which helps mediate gamification, to an extent) • Does not take into account social impact (e.g., an article trending on Twitter) • Complex, and, due to large dataset, difficult to replicate • Like all impact metrics, vulnerable to gamification (e.g., journal citation cartels) For an overview of how SJR is calculated, see: • Guerrero-Bote V, Moya-Anegón F.

• v • t • e The SCImago Journal Rank ( SJR) indicator is a measure of the scientific influence of scholarly journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where the citations come from.

A journal's SJR indicator is a numeric value representing the average number of weighted citations received during a selected year per document published in that journal during the previous three years, as indexed by Scopus.

Higher SJR indicator values are meant to indicate greater journal prestige. SJR is developed by the Scimago Lab, [1] originated from a research group at University of Granada. The SJR scimago journal rankings 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. The SJR indicator has been developed to be used in extremely large and heterogeneous journal citation networks.

It is a size-independent indicator and its values order journals by their "average prestige per article" and can be used for journal comparisons in science evaluation processes. The SJR indicator is a free journal metric inspired by, and using an algorithm similar to, PageRank.

In addition to the network-based SJR indicator, the SJR also provides a more direct alternative to the impact factor (IF), in the form of average citations per document in a 2-year period, abbreviated as Cites per Doc. (2y). [2] [3] Contents • 1 Rationale • 2 Computation • 3 See also • 4 References • 5 External links Rationale [ edit ] If scientific impact is considered related to the number of endorsements, in the form of citations, a journal receives, then prestige can be understood as a combination of the number of endorsements and the prestige or importance of the journals issuing them.

The SJR indicator assigns different values to citations depending on the importance of the journals where they come from. This way, citations coming from highly important journals will be more valuable and hence will provide more prestige to the journals receiving them.

The scimago journal rankings of the SJR indicator is similar to the Eigenfactor score, with the former being based on the Scopus database and the latter on the Web of Science database, [4] and there are other differences.

[5] Computation [ edit ] The SJR indicator computation is carried out using an iterative algorithm that distributes prestige values among the journals until a steady-state solution is reached.

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. The process ends up when the difference between journal prestige values in consecutive iterations do not reach a scimago journal rankings threshold value any more.

The process is developed in two phases, (a) the computation of Prestige SJR ( PSJR) for each journal: a size-dependent measure that reflects the whole journal prestige, and (b) the normalization of this measure to achieve a size-independent measure of prestige, the SJR indicator.
