Hybrid SPARQL Queries: Fresh vs. Fast Results [chapter]

Jürgen Umbrich, Marcel Karnstedt, Aidan Hogan, Josiane Xavier Parreira
2012 Lecture Notes in Computer Science  
Herein, we propose a hybrid query execution approach that returns fresher results from a broader range of sources vs. the centralised scenario, while speeding up results vs. the live scenario.  ...  For Linked Data query engines, there are inherent trade-offs between centralised approaches that can efficiently answer queries over data cached from parts of the Web, and live decentralised approaches  ...  Ladwig and Tran [8] categorise these approaches as: (i) top-down, (ii) bottom-up, and (iii) mixed strategy.  ...
