Summary
Data that exhibits a network or graph structure is ubiquitous, ranging from social networks on the internet to complex networks in life sciences. The combination of network structure within the data and an associated semantic imposes great challenges to searching and automatic reasoning. Our group therefore developed two system for managing large data graphs: RDF-3X, which aims for efficient query processing in classical data graphs, and URDF, which supports searching and reasoning under uncertainty.
