電腦與網路的發展帶給人們非常便利的生活，人們思考著如何將科技與生活空
間結合，將電腦與科技有智慧的融入生活中，可透過擷取環境中建置的感測元件、
網路服務等所提供的情境資訊，根據人們喜好的服務行為模式，配合蒐集情境資訊
並加以分析後，利用不同環境中的設備、網路與建置之服務系統加以整合與運用，
提供人們無所不在的個人化與可動態調適的服務，建構更舒適便利的智慧生活環境
。發展情境感知服務之研究主要著重於服務的開發與建置以達成智慧生活環境，本
研究為情境感知服務提供以本體論為基礎之平台，利用OWL語言建置情境模型，並且
依據所建構之情境模型建置推理系統，達到情境資訊的推論，提供情境感知服務所
需資訊進而達成適性化之服務，本系統採用服務導向的OSGi平台，情境感知服務透
過OSGi平台能方便的溝通與運作，最後本研究應用此基礎平台建構智慧型會議室系

The development of computing and networking brings people more convenient life.
People are thinking how to combine the technology with the life space to create
a smart context-awareness environment. Context-aware systems exploit the situational
context information to provide relevant information and services to users. According
to various needs of the users, building context-aware systems has a great challenge
in defining an architecture that supports context-aware services in intelligent
environments. This study proposes an ontology-based infrastructure to support
context-aware services. It uses the Web Ontology Language (OWL) to construct
context model, defines the rule-based inference systems, and integrates OSGi
framework to support context-aware systems. Finally, this study applies the
infrastructure to establish a smart meeting room system.
