The infrastructure project aims at supporting Projects 1-3 and will focus on three activities: (1) providing low-threshold access to sensitive SOEP data with fine-grained regional references at Bielefeld University, (2) extracting spatial and regional information from large quantities of unstructured (social) media data, and (3) integrating methodological and application-related teaching modules on regionalized SOEP data into the training of PhD students at SOEP and Bielefeld University.
