摘要翻译:
我们建议使用软约束作为面向服务体系结构建模的一种自然方式。在该框架中,约束被用来建模组件和连接器,约束聚合被用来表示它们之间的交互。在向服务提供者执行查询时,要衡量和考虑“服务质量”。一些例子包括客户要求的成本、性能和可用性水平。在我们的框架中,用约束的软度来表示QoS得分,并结合组件的软度来计算复杂服务的度量。

英文摘要:
We propose the use of Soft Constraints as a natural way to model Service Oriented Architecture. In the framework, constraints are used to model components and connectors and constraint aggregation is used to represent their interactions. The "quality of a service" is measured and considered when performing queries to service providers. Some examples consist in the levels of cost, performance and availability required by clients. In our framework, the QoS scores are represented by the softness level of the constraint and the measure of complex (web) services is computed by combining the levels of the components.
