RugCo: composing Web services from large repositories
Marco Aiello, Alex Telea, Nico van Benthem · 2009
In a service oriented architecture, loosely coupled software components are orchestrated as service in order to implement a working information system. How services are orchestrated is decided by developers and is also referred to as service composition. To stimulate research in the field of automatic service compositioning, an an-nual competition was started in 2005, called the Web Services Challenge (WSC). The RugCo system is the entry from the University of Groningen to the 2008 edition of the WSC. RugCo automatically composes Web services from a repository based on the semantics of a domain ontology and a user composition query. Using a beam search algorithm with straight-forward ordering heuristics, the system was able to find compositions for all challenge queries well within the time limit. In addition, RugCo was recognized for its flexible architecture based on modifiability and integratebility. This thesis decribes the RugCo approach and analyzes its results compared to other participating systems as a base for future participation and contribution to
