정확한 영상 검색을 지원하기 위해 다양한 데이터와 방법들을 통한 메타데이터 생성 연구들이 이루어지고 있다. 자막 데이터를 기존의 키워드 기반의 메타데이터 생성 방법을 이용했을 경우, 구어체, 불완전 문장의 특징을 가진 특징을 반영하는데 어려움이 있었다. 또한, 단순히 키워드 매칭에 의존하기 때문에 문장에 중의적 단어가 포함되어 있을 경우에 검색 정확도가 떨어진다는 한계점이 있다. 따라서, 본 논문에서는 이러한 문제를 해결하기 위해 문장 전체를 특정 단위로 표현한 메타데이터를 생성한다. 이를 위해 비지도 학습인 RNN-LSTM 기반 네트워크를 이용하여 자막을 인코딩하고 장면 지식으로 생성하는 방법을 제안한다. 실험에서는 본 시스템을 통해 임의의 자막을 입력하고 유사도 기반의 결과 비교를 통해 자막 메타데이터의 정성적 평가를 수행하였다.
