Service matching and collaboration for electronic commerce

We propose a software architecture for one-stop services of electronic commerce (EC). Users currently have trouble using multiple EC services because they are provided independently. Therefore a mediator that combines EC services and provides one-stop services to users would be useful. Service matching and service collaboration are important issues in the mediator because they are the main difficulties for users. The proposed architecture provides solutions to these issues. Multiple service assignment provides suitable combinations of EC services, flow division enables efficient execution of the combined EC services, and dynamic alternative service assignment enables flexible failure avoidance during the execution of combined services. These features make the proposed architecture a suitable mediator for EC services.
