초록

유비쿼터스 컴퓨팅 환경에서는 주변 환경에 의해 발생하는 방대한 컨택스트 정보에 대한 모델 정의와 컨택스트 인지를 통한 지능적인 서비스 제공을 위하여 컨택스트 정보 처리, 관리 및 추론과 관련한 연구가 필수적으로 요구된다. 그러나 현재 컨택스트 인지 분야에서는 고수준의 서비스 지원을 위한 온톨로지 특성을 효과적으로 반영한 모델링 기법이 부재하며, 지능적인 추론(응용, 조합)을 지원하는 기법 부재 및 컨택스트 정보간 상호운용성 지원의 한계를 가지고 있다. 따라서 본 연구의 최종 목표는 실세계에 존재하는 실체(entity)에 대한 상태를 특징화하고 정의하기 위한 방법으로 육하원칙을 적용한 온톨로지 기반의 컨택스트 인지 모델링 기법 컨택스트 인지를 위한 육하원칙 온톨로지를 개발하고 보다 양질의 지능화된 컨택스트 인지 서비스를 제공하기 위해 컨택스트 정보에 대한 관리 및 컨택스트 추론을 지원하는 프레임워크를 개발함에 있다.

Ubiquitous Computing is required to define models for broad context information occurrence by surrounding environment and to study how to model a mechanism for selectively collecting useful pieces of context information and providing relevant intelligent services. Further, studies are also required as to process of context information, and its maintenance and reasoning. However, current context-aware research area still lacks modeling technique that reflects the characteristics of ontology effectively for providing relevant intelligent services. It has also limitation about context reasoning and interoperability among context information. Therefore, this paper proposes ontology-based context-aware modeling technique and framework enabling efficient specification of context information for providing intelligent context-aware services that support context management and reasoning.
