Due to the heterogeneity of the sources, a more case-specific solution must be found for UDraCor in this initial step. Here, the conversion is a semi-automatic procedure with heavy use of string patterns and regex. At the same time, UDraCor takes a community-based corpus-building approach by inviting scholars specializing in Ukrainian studies to work on both technical and content-related tasks. This work on UDraCor once again shows how the technical task of corpus building and community activities are crucially intertwined.
