Abstract: Service composition is an effective means of building profit-added service in a service-oriented computing environment. Most of the current research neglects characteristics of domain business as well as successful domain experiences, so optimisation performance cannot be further improved in specific service context. Firstly, the concept of service pattern is proposed to describe the knowledge extracted from previous composite solutions in domain business. Both service patterns and related advantageous services are pre-computed and organised, so that they can be reused in optimisation of service composition. Then a pattern-based bi-objective service composition method whose objective is to obtain a service solution for maximisation of user satisfaction and service revenue quickly is presented. Experimental results show the effectiveness and advantages of the proposed approach.
