Service adaptation is one of the most important issues in SOC (Service Oriented Computing). This paper focuses on the issue of service behavioral adaptation and proposes an adapting method based on dependency graph. It can be divided into three sequential sub-problems: (1) service description-the foundation of service adaptation. We propose a formal approach to describing service behavior protocols; (2) mismatch definition-the identification of service mismatches. We define several kinds of behavior mismatches based on dependency graph; (3) service adaptation-the adaptor construction process. We detect all possible behavior mismatches and then generate different adaptors correspondingly.
