Analysing the coverage of the University of Bologna’s bibliographic and citation metadata in OpenCitations collections V.6

We present a step-by-step methodology for tracking the coverage of publications available in the CRIS (Current Research Information System) infrastructure of the University of Bologna and implemented in the IRIS platform, within the databases of OpenCitations. The methodology filters and transforms data dumps from IRIS and OpenCitations Meta and Index to create novel datasets that are used to perform quantitative analysis on the subject matter. Specifically, we quantify the proportion of IRIS publications included in OpenCitations Meta, examine the types of publications best covered, evaluate the number of citations within OpenCitations Index involving IRIS publications as either citing or cited entities, and the extent to which these citations reference works outside of IRIS. The research questions addressed in the study are: What is the coverage of the publications available in IRIS (strictly concerning research conducted within the University of Bologna) in OpenCitations Meta? What are the types of publications that are better covered in the portion of OpenCitations Meta covered by IRIS? What is the amount of citations (according to OpenCitations Index) coming from the IRIS publications that is involved in OpenCitations Meta (as citing entity and as cited entity)? How many of these citations come from and go to publications that are not included in IRIS? How many of these citations involve publications in IRIS as both citing and cited entities?
