语义Web服务系统中互操作问题的研究

以往的互操作机制没有确切地规定业务处理任务的行为，既使业务处理难以准确地进行任务指派，又难以满足Web上异构和分布的应用程序间语义互操作的需求。为此，提出了一套有效的互操作机制，该机制用接口技术抽象化地描述与Web服务调用实例相关的服务行为，有效地解决了服务双方的通讯和协作问题；用适当的调解技术解决交互过程中的各类异构问题。为了证实该机制，给出了在线健康咨询系统应用实例，并深入探讨了该系统的工作机理和互操作实现。

Problem of interoperability in semantic Web service system

Pervious interoperability mechanism didn't specify the behaviors of business processes, so it was difficult for business processes to accurately designate tasks and satisfy the requirement of semantic interoperability among distributed and heterogeneous applications on Web. In order to solve this problem, a set of effective interoperability mechanism was presented. Adopting interface technology to abstractly describe the service behavior, which was relevant to Web service. This mechanism effectively solved the communication and collaboration problems between both sides of the services, and it also used appropriate mediation technology to solve heterogeneous problems during the course of service interaction. In order to testify the mechanism, a case of Online Healthy Consultant System (OHCS) was provided, and its working principles and interoperability implementation were also discussed in detail.
