초록
유비쿼터스 컴퓨팅 환경에서 사용자의 주변 정보를 인지하고 이에 알맞은 유용한 서비스를 제공하기 위한 상황인 식 기술이 다양하게 연구되고 있다. 입력된 주변 상황정보를 저장하고 적절히 가공하여 현재 상황에 알맞은 서비스를 제공하기 위해서는 상황 정보에 대한 모델이 필요하다. 상황정보의 모델로 여러가지 방법론이 사용되고 있으며 최근 에는 재사용성 및 확장성을 가진 온톨로지 기반의 상황 모델이 관심을 받고 있다. 본 논문은 다양한 상황 모델링 기법 과 평가방법을 알아보고 온톨로지 기반의 상황 모델 및 상황인식 미들웨어에 대하여 비교 정리하였다.
Abstract
There have been a large amount of researches on context-awareness technology for recognizing the context information of users and providing useful services to them. In order to manage context information, a system needs to formally represent context information. Many researchers have proposed many context models for effective and efficient manipulation of context information. In this paper, various context modeling approaches are summarized with a special emphasis on ontology-based context models and context-awareness middlewares.
