These are the motivations behind the “Wikipedia Citations in Wikidata” project , supported by a grant from the WikiCite Initiative. From January 2021 until the end of April, the team of Silvio Peroni (co-founder and director of OpenCitations), Giovanni Colavizza, Marilena Daquino, Gabriele Pisciotta and Simone Persiani of the University of Bologna (Department of Classical and Italian Philology) worked on the development of a codebase to enrich Wikidata with citations to academic publications that are currently referenced in English in Wikipedia . This codebase is divided into four software modules in Python and integrates new components (a classifier to distinguish citations based on the cited source and a search module to equip citations with identifiers from Crossref or other APIs). In doing so, Wikipedia Citations extends previous work that focused only on citations that already have identifiers...."
