스마트 폰의 등장으로 인해 사용자들은 모바일 기기를 통해 언제 어디서나 인터넷 서비스를 이용할 수 있게 되었고 더불어 다양한 앱을 통해 기존에 PC에서 제공되던 서비스들이 모바일 기기로 이동하게 되었다. 이러한 변화는 TV시장에도 영향을 미치게 되었고 TV에서도 인터넷 서비스뿐만 아니라 다양한 앱 서비스를 이용할 수 있는 스마트TV 시대를 열게 되었다. 스마트 TV시스템은 방송망과 인터넷 망을 통해 사용자에게 보다 다양한 멀티미디어 콘텐츠 서비스를 제공할 수 있게 되었으나 각 인터넷 콘텐츠 제공자가 앱 형태로 콘텐츠를 제공함으로써 다양한 콘텐츠 제공자로부터 사용자가 원하는 멀티미디어 콘텐츠를 검색하는 데에 한계가 있었다. 본 논문은 사용자 키워드 검색문 의미해석을 통해 서로 상이한 멀티미디어 콘텐츠 메타데이터 정보 구조를 가지고 있는 콘텐츠 제공자들이 효과적으로 검색결과를 제공할 수 있는 스마트TV통합검색시스템에 대하여 기술한다.
