A Knowledge-Based Service Composition Algorithm with Better QoS in Semantic Overlay

A Knowledge-Based Service Composition Algorithm with Better QoS in Semantic Overlay

A semantic overlay network (SON) is a visual framework clustered under similar metaknowledge units such as ontologies, algorithms, and rule engines. Knowledge-based service composition (KC) has become a prominent aspect of building new and creative composed service through a combination of semantica...
