Declan O'Sullivan and his team are developing new theoretical, conceptual and algorithmic techniques for automated data integration in dynamic environments. The integration step of the data lifecycle has typically been a labour intensive activity, with increasingly brittle results due to the dynamic nature of today's environments. A systematic mechanism for continuous data integration is lacking, but is needed to deal with the dynamism of the data (velocity, variety) and schemata characteristics of modern environments. The team has particular expertise in Semantic Web and Linked Data environments.
