Abstract
Public procurement accounts for a substantial part of the public investment and global economy. Therefore, improving effectiveness, efficiency, transparency and accountability of government procurement is of broad interest. To this end, in this poster paper, we present our approach for integrating procurement data, including public spending and corporate data, from multiple sources across the EU into a semantic knowledge graph. We are aiming to improve procurement processes through supporting multiple stake holders, such as government agencies, companies, control authorities, journalists, researchers, and individual citizens.
