Abstract

For digital TV, the recommendation of u-health personalized service of semantic environment should be done after evaluating individual physical condition, illness and health condition. The existing recommendation method of u-health personalized service of semantic environment had low user satisfaction because its recommendation was dependent on ontology for analyzing significance. We propose the personalized service recommendation method based on Naive Bayesian Classifier for u-health service of semantic environment in digital TV. In accordance with the proposed method, the condition data is inferred by using ontology, and the transaction is saved. By applying naive bayesian classifier that uses preference information, the service is provided after inferring based on user preference information and transaction formed from ontology. The service inferred based on naive bayesian classifier shows higher precision and recall ratio of the contents recommendation rather than the existing method.

디지털 TV에서 시멘틱 환경의 유헬스 개인화 서비스 추천은 개인의 신체조건, 질병, 건강상태를 평가해서 이루어져야 한다. 기존의 시멘틱 환경의 유헬스 개인화 추천 방법은 온톨로지에 의존하여 의미 분석으로 추천을 하기 때문에 사용자 만족도가 떨어진다. 이에 본 논문에서는 디지털 TV에서 시멘틱 환경의 유헬스 서비스를 위한 나이브 베이지안 필터링 기반 개인화 서비스 추천 방법을 제안한다. 제안하는 방법은 온톨로지를 이용하여 상황데이터를 추론하여 트렌젝션을 저장 하고, 선호도 정보를 이용한 나이브 베이지안 필터링 기법을 사용하여 온톨로지로부터 생성된 트렌젝션과 사용자 선호도 정보를 이용하여 추론하여 서비스를 제공한다. 나이브 베이지안 필터링 기반으로 추론된 서비스는 기존의 필터링 방법 보다 콘텐츠 추천의 높은 정확도와 재현율을 보인다.
