Scalable Federated Querying of Heterogeneous Web Interfaces for Linked Data

Querying Linked Data currently requires a highly expressive query interface. Because the computational complexity of such interfaces is too demanding, the majority of knowledge cannot be queried. This research focuses on querying heterogeneous, less expressive interfaces. To efficiently compute results, the client needs to divide it across different servers, such that the limited expressivity of each interface is maximally exploited.
