Cheung, Jiming Liu, Maggie M. Wang, Hoi-Fai Wong, Kevin Tsang • Wisdom Web (Semantic Web + Grid + Autonomy) • (A) Services Discovery and Selection • Wrapping the Grid resources with semantics to ease the distributed resource management issues. • E.g., discovering a host “running Unix” with an “average response time = 1 sec.” for executing a particular “C4.5” implementation. • (B) Services Flow Planning (followed by service orchestration) • Solving user-defined problems autonomously remains a challenge (e.g., asking via a Grid connected mobile phone “Please find me a stock worth buying”).
