The 9th RISIS Policymakers Session took place on the 3rd December in an online format (11 am ��� 13 am) with a presentation of Dr. Abdullah G��k (University of Strathclyde), entitled What is really social innovation in practice? aiming to explore the complex dimension of Social Innovation and in particular to analyse the correspondence of the different definitions of Social Innovation, using RISIS-ESID European Social Innovation Database. Emanuela Reale illustrated the RISIS project, aims and achievements reached so far. Dietmar Lampert, Centre for Social Innovation, has been involved as discussant. ESID is a comprehensive database of social innovation projects utilising machine learning and text-mining to collect data. The study conducted using ESID is supported by a web app (https://bit.ly/ESIDapp) which enables the reader to view the underlying data and interactively engage with the analysis. Through an extensive review of literature of the multitude of definitions of Social Innovation and based on previous research, the researchers identify four overall components (objectives; actors and actor interactions; outputs; innovativeness) that the definitions use in different combinations. ESID does not adopt a specific definition of Social Innovation but scores projects based on the four components mentioned above, which enables its users to construct a query based on a preferred definition. The researchers consider these components as different types of SI, each indicating to a set of specific features. Currently ESID contains 11,441 projects from 153 countries. The analyses focuses on over 6,000 SI projects included in ESID, illustrating the prevalence of these types of SI as well as their relationship with each other, geography and topics. The study conducted by University of Strathclyde shows that the topics derived from EU policy priorities have a significant correspondence in real life SI projects in the EU, with only about 15% of the projects not associated with at least one of the topics compared to about 35% in North America. The analysis shows also that there is significant ���policy pull��� on social innovation topics. Only about 10% of the projects are not associated by one of the EU priority societal grand challenges, compared to one third of the North American projects.
