초록

최근 소셜 네트워크 사용자들이 늘어나면서, 각 지역에서 관심 받고 있는 사회적인 이슈나 재해 등과 같은 이벤트에 대한 정보들이 소셜 미디어 사이트를 통해 실시간으로 빠르게 대량으로 게시되고 있으며, 사회적 파급효과도 매우 커지고 있다. 본 논문에서는 지역정보를 가진 트위터 데이터를 이용하여 특정 시간, 지역에 사용자들이 관심을 가지고 있는 이벤트를 탐지하는 방법을 제안하고자 한다. 이를 위해 트위터 스트리밍 API를 이용해 데이터를 수집하고, 트윗의 키워드들의 시간에 따른 빈도수를 분석하여 정상적인 패턴과 다른 패턴을 가진 키워드를 이벤트로 추출하고, 같은 이벤트에 대한 키워드들을 군집화 하기 위해 co-occurrence 그래프를 이용하여 이벤트 감지 시스템을 구현하였다. 그리고 실험을 통해 제안한 기법의 유효성을 검증한다.

As the number of social network users increases, the information on event such as social issues and disasters receiving attention in each region is promptly posted by the bucket through social media site in real time, and its social ripple effect becomes huge. This study proposes a detection method of events that draw attention from users in specific region at specific time by using twitter data with regional information. In order to collect Twitter data, we use Twitter Streaming API. After collecting data, We implemented event detection system by analyze the frequency of a keyword which contained in a twit in a particular time and clustering the keywords that describes same event by exploiting keywords' co-occurrence graph. Finally, we evaluates the validity of our method through experiments.
