소셜 네트워크 서비스(SNS: Social Network Service)는 사용자들 간의 정보공유 및 관계형성을 위한 Web 2.0 기반 기술로써, 관계를 통해 형성된 사용자들 간의 상호작용을 지원하는 서비스이다. SNS 기술은 개인들 간의 관계 뿐 아니라 공공부문의 서비스의 제공자인 정부부처 및 공공서비스 제공기관들과 사회구성원들 간의 관계형성을 위한 기술로써 각광받고 있다. 최근에는 모바일 기술의 발전에 힘입어 트위터, 페이스북과 같은 SNS 이용자가 빠르게 증가하고 있으며 그 활용범위 또한 개인 사용자들 간의 정보공유에서 기업과 고객, 공공과 국민의 관계까지 확장하고 있다. 본 논문에서는 SNS가 공공부문의 서비스 제공을 위한 수단으로 활용한 사례를 통해 요구되는 기술을 제안한다.

스마트 디바이스가 대중화 되면서 각종 사건 사고에 대한 데이터가 SNS 상에 실시간으로 업데이트 된다. SNS의 이런 특성을 이용하여 이용자 개개인이 사고감지센서의 역할을 하면 빠른 사고감지가 가능하다. 하지만 기존 연구들은 단순히 키워드의 출현 빈도로 사고를 판단하는 방식과, 문법파괴 요소가 많은 트위터의 특성으로 인해 정확성에서 한계를 보인다. 본 연구에서는 사고감지의 정확도를 높이기 위해 형태소로 분석한 트윗을 벡터화하여 다층퍼셉트론신경망으로 학습시키는 모델을 구현하였다. 연구 결과 일반명사로 이루어진 40개의 단어를 사용했을 때 가장 높은 82.58%의 정확도를 얻었다.

트위터 이용자 수 증가로 인해, 유저의 타임라인에 하루 새롭게 기재되는 트윗 수가 급증하는 정보과다 현상이 중요한 이슈로 자리 잡은 지 오래다. 이에 본 논문은 이고-네트워크 정보를 바탕으로 학습 된 분류 시스템을 이용해 각각의 이고 유저마다 트윗 추천에 유리한 추천 방식을 예측하고, 이를 기반으로 선호할만한 트윗을 우선적으로 선별해주는 그래프 기반 트윗 추천 시스템을 제안한다. 실험을 통하여 단일한 추천 방식보다, 최고 11.5% 추천 정확도 성능이 향상함을 확인하였다.
