Abstract

Due to the improvement of quality of life, health care is a main concern of modern people, and the demand for healthcare system is increasing naturally. However, it is difficult to provide customized wellness information suitable for a specific user because there are various medical information on the Internet and it is difficult to estimate the reliability of the information. In this study, we propose a user - centered service that can provide customized service suitable for users rather than simple search function by classifying big data as text mining and providing personalized medical information. We built a big data system and measured the data processing time while increasing the Hadoop slave node for efficient big data analysis. It is confirmed that it is efficient to build big data system than existing system.

삶의 질의 향상으로 인하여 건강관리는 현대인의 주요 관심 사항이며 자연스럽게 헬스케어 시스템에 대한 요구가 증가하고 있다. 그러나 인터넷 상에는 다양한 의료 관련 정보가 존재할 뿐만 아니라 이 정보들의 신뢰성 또한 가늠하기 힘든 것이 현실이므로, 특정 사용자에게 적합한 맞춤형 웰니스 정보 제공은 어려운 것이 현실이다. 본 연구에서는 빅데이터를 텍스트 마이닝으로 분류하여 사용자 맞춤형 의료정보를 제공함으로서 단순 검색기능이 아닌 사용자에게 적합한 맞춤 서비스를 제공할 수 있는 사용자 중심의 서비스 제공 방법을 제안한다. 효율적인 빅데이터 분석을 위해 하둡 슬레이브 노드를 증가하면서 데이터 처리시간을 실험하였다. 기존 시스템보다 빅데이터 시스템을 구축하는 것이 효율적임을 확인하였다.
