I'm a Ph.D. Research Fellow at the Department of Informatics, University of Oslo, Norway. My background is a Master's in theoretical astrophysics and 8 years of IT industry experience. There's an official institutional homepage and my personal homepage (usually outdated).
Federated SPARQL queries are often not practical because the federation engine has insufficient information to optimize, or the information is so large that it defeats the purpose of optimizations to begin with. I plan to help remedy this problem by computing very compact digests and expose them in the service description. Furthermore, I plan to use statistical design of experiments to create a comprehensive test of the performance gain achieved.
