Abstract: By analyzing the difficulty in information heterogeneity in the oceanic field,a hierarchical architecture based on SOA is proposed to solve the problem of information integration and sharing.This model defines a domain ontology,establishes mapping relation between fields and heterogeneous resources,and defines unified exchange data format as the basis of data integration.Together with the ontology,this model proposes solutions for exchange data.In addition,service collaboration is achieved by using service integrator.Finally,this model is applied to Oceanic Disaster Response System in East China Sea and an example is given to testify the validity and feasibility.

Key words: domain information sharing, ontology, data integration, exchange data, service integration

摘要: 通过分析我国海洋领域中资源异构的问题,提出一个基于SOA的层次结构共享框架模型以解决信息资源集成和共享。该模型定义领域本体,建立领域间、异构信息资源间的映射关系,定义统一交换数据格式作为数据集成基础,并结合本体给出交换数据解决方案,同时利用服务集成器实现服务协同。将模型应用于东海海洋灾害应急系统,通过实例验证模型的正确性与可行性。
