基于语义Web技术的上下文感知的智能移动服务

语义Web技术应用于上下文感知的智能移动服务，通过构建上下文信息本体，使得移动服务的实体之间可以进行上下文信息共享和语义互操作，并进行上下文信息推理，实现智能服务。本文首先介绍了语义Web及本体技术，其次阐述了语义Web技术应用于上下文感知的移动服务，然后详细分析了智能移动服务中的上下文信息本体构建，包括通用的上下文信息本体、用户概况本体、情境本体以及服务本体等，接着介绍了相关的研究项目，最后进行展望和总结。

Context-aware Intelligent Mobile Service Based on Semantic Web Technologies

More and more people access Web through mobile devices, such as mobile phones and personal digital assis tants. In order to acquire rich and flexible mobile service, context information within which mobile users operate should be understood. Semantic Web is the evolution of the current Web, which enables computers to understand Web infor mation. Semantic Web and ontology technologies are the key requirement for realizing context sharing, semantic interoperation and context reasoning. Applying semantic Web technologies to context-aware intelligent mobile service was analyzed in this thesis. At first an overview of semantic Web and ontology technologies was introduced. Next why semantic Web technologies were applied in context-aware intelligent mobile service was described. Then context ontology architecture in context-aware mobile service was discussed, including common context ontology, user profile ontology, situation ontology and service ontology. At last some related research projects were listed and this document was summarized.
