Abstract A heterogeneous system interoperation framework based on multi-layer ontology was proposed to solve the problems of integrating heterogeneous systems during the business collaboration. Using the key components of business collaboration: product, activity, process as a point of departure, the framework defines a multi-layer ontology model composed of product knowledge ontology, activity ontology, and process ontology, to realize the semantic consistency of multi-components in collaboration process. Product knowledge ontology supports the product specification in activity ontology|activity ontology describes the concept, function, implementation of each procedure or action in process|and process ontology connects various activities by control construction to compose business process. The combined mapping theory and the semantic similarity semantic algorithm realize the semantic mapping and integration among different ontology libraries and achieve upper ontology. OWL-S is used to describe the release and request of Web service. The example of cloth sale showed how the business interoperation mechanism works to achieve business ordering process matching using the ontology mapping module and the semantic matching module in the prototype system.

基于本体的面向业务协作的异构系统互操作关键技术
为了解决目前业务协作过程中异构系统集成困难的问题,提出了基于多层次本体的异构系统互操作框架.该框架以业务协作过程中涉及的关键要素——产品、活动和过程为出发点,为实现协作过程中多要素的语义统一问题,提出了由产品知识本体、活动本体、过程本体组成的多层次本体模型.产品知识本体支持活动本体中的产品描述；活动本体是对过程中每一个步骤或行动的概念、功能、执行情况的描述；过程本体通过控制结构将各个活动连接起来,组成业务过程.采用组合映射理论和语义相似度算法实现不同本体库之间的语义映射和语义集成,从而构成顶层本体库,并通过OWL-S顶层服务本体描述发布和请求Web服务.以服装销售的业务过程为例,采用业务协作互操作机制,通过自行开发原型系统中的本体映射和语义匹配模块,解决了不同企业的订单活动的协作问题.
