Evidencing Open Access Citation Advantage using SciVal

This conference contribution introduces a technique that can be used to explore the relative citation performance of publication sets with various modes of open access (OA). We give two methods for distilling a publication list into Gold, Hybrid Gold, Green, Bronze OA and Closed publication sets. One method uses SciVal functionality with limited further data manipulation; whilst the other utilises the Unpaywall Simple Query Tool. A comparison of the results for an entity of approximately 4000 research outputs is shown. We suggest some metrics that may be useful in characterising citation advantage of open vs. not open research outputs.
