Large Scale Web Service Discovery and Composition using High Performance In-Memory Indexing

With the growing number and ubiquitous usage of Web services throughout the service-oriented community, the need to find service descriptions in a given repository, as well as composing them to a desired output, becomes a major issue in both research and corporate environments. Considering emerging semantic technologies and methods for service matching that is not limited to a mere syntactic level, the need for fast discovery and composition algorithms arises. In this paper we present a system created at the VitaLab in Vienna with the purpose to overcome the obstacles which are implications of both, large service repositories and large ontologies to describe semantic relations.
