The “Journal Rank (SJR)” filter can be used to explore the articles and the relationships that originate from journals with a preferred SCImago Journal Rank (SJR).
The SJR is a publicly available impact factor 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 2020 to documents published in the journal in 2017, 2018 and 2019). Journals are clustered into quartiles according to their score, relative to peers. You can find out more about the SJR score here.
In Causaly, you can choose one of the following options (Figure 1):
Option 1 - Select a quartile (quartile boxes)
The journals of a specific subject area (i.e Oncology journals, Immunology journals etc.) have been ranked according to their SJR and divided into four equal groups, four quartiles.
- Quartile Q1: Publications in the top 25% journals of a specific subject category
- Quartile Q2: Publications in the 25-50% group of journals
- Quartile Q3: Publications in the 50-75% group of journals
- Quartile Q4: Publications in the 75-100% group of journals
- Unassigned: Publications in journals that do not have an SJR score
Option 2 - Specify a custom SJR score (SJR boxes)
You can specify a preferred minimum and/or maximum value of SJR by completing the boxes below the quartiles. If you want to include in your results articles without an SJR score, you can select the “Unassigned Score” option, underneath the Min/Max SJR boxes.
Figure 1: The “SJR” filter. Numbers in brackets indicate the number of articles under a specific category, as we are exploring the Articles tab. For example, there are 8,906 articles found within the Q1 quartile, 2,669 articles found within the Q2 quarticle, etc.
Use Case: Breast Cancer Therapeutics In Highly cited Journals.
To explore this use case in Causaly, the powerful and time-saving filters of the Intelligent and Advanced Search Modules will be used.
Initially, the search will include all possible treatments of breast cancer. Subsequently, in order to filter for highly cited journals, the “Journal Rank (SJR)” filter will be used. The user will set 10 as the minimum value of the SJR (Figure 2).
The exact search results can be found here.
Figure 2: Completing the minimum value box with ‘’10’’ to refine the results and retrieve articles from journals with an SJR ≥10. In this example, all the 182 returned articles are part of the top quartile of their respective categories, as expected. There are 214 articles that do not have an SJR score assigned. You can include those by selecting the “Unassigned Score” box.
The results displayed will only contain articles published in well-recognized journals (SJR≥10) (Figure 3).
Figure 3: Articles from the “Journal of Clinical Oncology’’ and ‘’Nature genetics’’ journal with 2019 SJRs of 10.054 and 21.508, respectively.
Another way to explore publications from highly cited oncology journals, is to select the quartile Q1 (Figure 4).
Figure 4: Selecting the quartile Q1 to refine the results to publications from highly-cited journals. In this case, the results include the 3,2K articles published in journals that belong to the Q1 quartile.
The results will be obtained from the top quartile journals. The exact search results can be found in this link.
