Abstract

차세대 IT융합기술의 발전에 따라 개인화 건강관리 서비스를 위한 인프라스트럭처가 구축되면서, 사용자의 선호도 기반 서비스의 중요성이 부각되고 있다. 만성질환자가 증가함에 따라 건강관리 서비스는 특정 질병의 치료 및 관리에서 서비스 대상자에 대한 식이영양 관리로 진화하고 있다. 본 논문에서는 건강관리를 위한 혼합 필터링을 이용한 개인화 식이영양 콘텐츠 추천을 제안하였다. 제안한 방법에서는 유사한 콘텐츠만을 제공하는 추천 특수화 경향을 개선하기 위해 협력적 필터링과 이미지 기반 필터링을 결합한 혼합 필터링을 사용한다. 이를 웹 어플리케이션으로 구축하여 논리적 타당성과 유효성을 검증하기 위해 실험적인 적용을 시도한다. 따라서 식이영양 콘텐츠를 추천하여 건강관리에 대한 만족도와 서비스의 질을 향상시켰다. 연구결과를 활용하면 시장성 증대와 고부가 가치를 창출할 수 있을 것으로 기대하며 다양한 응용분야에 활용이 가능하다. With the development of next IT convergence technology and the construction of infrastructure for personalized healthcare services, the importance of services based on user's preference is being spotlighted. Healthcare service have been progressed as treatment and management for specific diseases and dietary nutrition managements to customers according to the increase in chronic patients. In this paper, we proposed the personalized dietary nutrition contents recommendation using the hybrid filtering for managing health. The proposed method uses the hybrid filtering through combining the collaborative filtering and the image filtering in order to reinforce the special trend that recommendation provides similar contents. We developed the Web application for this purpose, and experimented with it to verify the logical validity and effectiveness. Accordingly, the satisfaction and the quality of services will be improved the healthcare by recommending the dietary nutrition contents. This evaluation found that the difference of satisfaction by service was statistically meaningful and showed high satisfaction.
