Spotlight on: Visualizations in Journal Citation Reports
One of the key features of Journal Citation Reports (JCR) on InCites is its graphics. We introduced significant enhancements to the graphical representation of the major data points available in the product.
On the main Journal Ranking and Category Ranking pages, you will see a link-and-node visualization when “Show Visualization” is chosen. By filtering your view, you can see the relationships among journals or categories.
For example, if you were to look at the top five journals in the category Allergy, you can see how they relate to each other through the link-and-node visualization. The nodes represent the Journal Impact Factor, and the links represent the flow of citations between the linked journals. So in this example, you can see that the Journal of Allergy and Clinical Immunology has the largest Journal Impact Factor of the group, and has a stronger citation relationship with Allergy than with Contact Dermatitis.
On the Category Ranking page, the nodes represent the number of journals in the category, and the links once again represent the flow of citations between the linked categories. If you were to look at the five agriculture-related categories, you would see that Agronomy is the largest category, and has a stronger citation relationship with Agricultural Engineering than it does with Agricultural Economics & Policy.
Inside the Journal Profile pages, you can view the metrics as trend graphs, showing either the most recent 5-year period, or all years. To access these graphs, click “graph,” and then scroll down below the Key Indicators table to see your graph, toggling between the time period options on the graph itself.
The final new visualization offered in JCR on InCites is the Journal Relationships graph. This interactive visualization shows the relationship between the parent journal (the journal whose profile page a user is on) and the top 20 cited or citing journals, depending upon the selection, for all years of the cited or citing relationship.
“Cited” indicates citations flowing TO the parent journal from other journals. (cites received)
“Citing” indicates citations given BY the parent journal to other journals. (cites given)
On the diagram, the top 20 cited or citing journals are displayed as arcs on the circle. The size of each arc is indicative of the relative citation relationships to that journal. The thickness of the chords connecting the arcs is demonstrative of the strength of citation relationship between the journals.
The Journal Relationships diagram includes several interactive features:
- Hover over arcs to display the journal Impact Factor;
- Hover over chords to display the citation relationship to the parent journal;
- Click the title of any journal in the arc to go straight to that title's profile page;
- Click the arc for any title to see that journal's relationship to the top twenty journals in the parent journal's network.
In the screenshot below, you can see that Nature Materials has been cited by Physical Review B 2294 times over all years.
As mentioned in my last post, you can also now download the Journal Relationships visualization. After the visualization loads, select the PDF download option. The PDF will download with the visualization and the relevant data table.
