摘要: 为应对情景应用构建过程中,待连接服务之间的不匹配现象,提出了一种半自动的服务适配方法。提出了以树型文法表示服务的消息,并基于树型自动机的代数操作定义了服务的适配操作集,分析了该操作集的完备性。在此基础上,提出了支持情景应用构建的服务适配方法。通过在生物信息情景应用构建场景中的应用,表明该方法具有即时性好、适应服务差异以及无需硬编码的优点。

Abstract: To solve the mismatch of connected services in situational applications, a semi-automatic service adaptation approach was proposed. Service messages were described by tree grammar and operations for service adaptation were defined based on tree automata algebra. The completion of the set of service adaptation operations was also analyzed. And then, the approach to service adaptation for constructing situational applications was proposed and applied to building situational applications with a scenario of bioinformatics experiments. The results show that the adaptation based on the proposed approach is just-in-time, adaptive to the heterogeneity of services and of no need for hard-coding.
