The scholarly literature is a vast store of formalized human knowledge, interconnected by citations between publications.
Looking at these citations is one way to measure the influence of scholarly research. Metrics like h-index—prominently displayed by services such as Google Scholar—measure influence by counting citations. But with more complete data about these citations getting better and more accessible every day, we can do better.
The scholar visualization tool shows the influence a researcher has had both within his or her own field and across other fields, illustrating a local view of a scholar's network of influence and telling the story of how this influence has developed over time. The author of interest is represented as the central node in a network, and other papers that have cited papers written by this author are shown as circular nodes surrounding the central one. The animation starts early in the researcher's career, and progresses forward in time. As new papers appear, they send out links representing citations, both to the central node and to other nodes that appear in this network.
In order to reduce the visual complexity of the graph, not all of the papers that have cited the central scholar are represented. Rather, the most influential papers (by Eigenfactor score) are selected to be visualized as nodes in the network.
Below the network diagram, line charts show key indicators over time:
A note on comparing authors:
Scales are relative to each author, so the size of the nodes and the y-axes on the timelines are not consistent between authors. For this reason, direct comparison between different authors is not recommended. However, comparing the relative densities of the graphs can reveal information about the types of community represented by the citation networks.
Frequently Asked Questions
What can this show me that other services can't?
Let's take Google Scholar for example. An author's Google Scholar profile includes information about that author's publications, measures and displays of number of citations over time, and a couple of basic citation metrics including h-index. An author's scholar.eigenfactor.org profile goes beyond this by taking into account not just the number of citations a scholar has received, but where these citations are coming from. Exploring these incoming citations through our visualization and analysis tools can give a more detailed picture of the extent and quality of the influence a scholar has had.
I'm seeing papers in my visualization from [Medicine, Sociology, Psychoceramics...]. What's going on here? These are not my papers!
If you are the author at the center of the visualization, the papers that appear around you are important papers that have cited your work, not necessarily papers that you have authored. This is how the visualization shows what sort of influence the center collection may have had—by highlighting papers published since that have found value in one or more of the center papers.
Do I really need to register an account?
Having an account where you can manage your own paper collections is the best way to create meaningful collections and visualizations. We will, of course, never spam you or share your email.
I have a question/suggestion/idea! How can I get in touch with you?
We'd love to hear your feedback. Please direct it to firstname.lastname@example.org.
