2010 2010 IEEE International Conference on Service-Oriented Computing and Applications (SOCA)  
We present RuGQoS'10 system for QoS-Aware Web services composition.  ...  The availability of Web services with similar functionality but different QoS values creates new challenges for Web services composition: not only functional properties of the composed service must be  ...  All previous services in the composition one can find by looking recursively on the input concepts to the last service. We create the concept map CMP for this. The map has all concepts as keys.  ...
