基于本体的信息集成框架研究

为了解决信息集成中的语义异构问题,引入本体技术,借鉴"Mediator/Wrapper"体系结构,结合混合本体以及WebServices技术,提出了分布式网络环境下的基于本体的信息集成框架,阐述了如何利用本体技术解决语义异构问题,给出了框架的层次结构以及关键技术,包括本体构建、查询处理和服务注册中心,然后利用原型系统验证了框架是可行的。该框架解决了信息集成中的语义异构问题。

Research on Ontology-Based Information Integration Framework

Ontology technique resolves the problems of semantic heterogeneity of information integration,proposes the ontology-based information integration framework based on the architecture of "Mediator/Wrapper",mixed ontology and Web Services,then expounds how to use ontology to solve the problems of semantic heterogeneity,the structure and key technique of the framework are given.The key technique includes building ontology,inquiry processing and the registered center of services.the framework is verified by the prototype system.The framework resolves the problems of semantic heterogeneity of information integration.
