情境感知的集成融汇服务方法研究

Study on Context-aware Service Mashup Implementation

探讨基于情境感知技术实现集成融汇服务的方法。在调研国内外相关研究进展的基础上,提出实现情境感知的集成融汇服务所需的几个功能模块,包括情境信息获取、情境建模、情境感知的服务发现、情境感知的服务组合等。重点分析情境建模技术与情境感知的服务发现技术,构建个性化情境本体模型CA-PLE,并将情境推理技术与语义匹配技术相结合,以主动提供与用户需求匹配度高的服务。

This paper presents the approach to implement context-aware mashup. Based on the current related resear- ches, the authors put forward the main function modules to achieve context-aware mashup, such as context information acquisition, context modeling, context-aware service discovery, service composition, and so on. Taking the technology of context modeling and context-aware service discovery as the key problem, this paper proposes a context model CA-PLE, then utilizes context inference and semantic matching to discover the services most in need.
