摘要
介绍了服务映射库、协同网和任务情景的基本概念,提出了基于协同网和任务情景的服务组合方法.对用户查询请求的每一个输出对象单独生成完备协同网集,将输出的各协同网组合成组合服务以满足用户的需求,通过基于综合任务情景相似度的方法选取最佳组合服务并返回用户.结果表明,所提出的方法能够提高服务组合的成功率和效率.
The basic concept o{ service mapping repository, collaboration network and service task circum- stance was introduced. An approach based on collaboration network and task circumstance to compose services automatically was proposed. First, this method built a complete collaboration network for every output; next, the collaboration networks were combined into a composite service to meet the needs of us- ersl finally, best composite service was returned to the user based on compatibility of synthetical task cir- cumstance. The experimental results show that the method proposed can improve the success rate and effi- ciency of service composition.
