Giving Meaning to GI Web Service Descriptions
Florian Probst, Michael Lutz · 2004
Current GI service composition based on syntactic descriptions such as WSDL are error-prone because the meaning of the labels used in these descriptions is unclear. We identify three types of problems that can result from such semantically heterogeneous descriptions during service composition. These problems call for a Semantic Reference System for semantically annotating symbols, referencing symbols to concepts and semantically grounding these concepts. We present a three level architecture for such a Semantic Reference System and illustrate how it can be used for solving the problems identified using a real world example for service composition.
