Abstract--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 satisfied, but also non-functional
properties such as response time and throughput.
We present RuGQoS'10 system for QoS-Aware Web services
composition. The concept mapping technique allows to find the
best possible composition w.r.t. some QoS parameters without
performing a brute-force search.
I. INTRODUCTION
With the introduction of Web services came the possibility
of services composition [1][3], the process of combining
basic services to satisfy complex tasks. Recently, the quality
of service values increasingly affect the satisfaction of a
