Abstract

Online news on the Internet, as published open data, contain facts or opinions about a specific affair and hence influences considerably on the decisions of the general publics who are interested in a particular issue. Therefore, we can predict the people's choices related with the issue by analyzing a large number of related internet news. This study aims to propose a text analysis methodto predict the outcomes of events that take place in a specific place. We used topics of the news articles because the topics contains more essential text than the news articles. Moreover, when it comes to mobile environment, people tend to rely more on the news topics before clicking into the news articles. We collected the titles of news articles and divided them into the learning and evaluation data set. Morphemes are extracted and their polarity values are identified with the learning data. Then we analyzed the sensitivity of the entire articles. As a result, the prediction success rate was 70.6% and it showed a clear difference with other analytical methods to compare. Derived prediction information will be helpful in determining the expected demand of goods when preparing the event.

공개된 데이터인 온라인 뉴스 기사 중 상당수는 도시와 같은 특정 장소에서 발생하는 이벤트에 관련된 사실과 의견을 담고 있어 독자의 의사 결정에 영향을 끼친다. 따라서 대량의 인터넷 뉴스 기사를 분석하면 향후 사람들이 특정 이벤트에 대하여 어떠한 선택을 할지 예상할 수 있을 것이다. 이에 본 연구는 온라인 뉴스 기사 제목을 형태소 분석하여 특정 장소에서 이루어질 이벤트의 성과를 사전에 예측하는 방법을 제안하고자 한다. 기사 제목은 기사의 가장 핵심적인 내용을 담고 있어 본문보다 사실과 의견이 더 정확하게 발현될 뿐 아니라, 모바일 환경에서는 기사 본문보다 더 큰 영향력을 가지기 때문에 이벤트의 성과 예측에 효과적인 자료이다. 이에 인터넷 뉴스 기사의 제목을 수집하여 학습 데이터와 평가 데이터로 구분하고, 학습 데이터에서 유의한 극성을 보이는 형태소를 추출하여 전체 기사의 제목을 감성 분석하였다. 여기에 뉴스 기사가 갖는 특성이 반영될 수 있도록 기사 검색량과 기사 산출량 정보를 변인에 추가하여 이벤트 성과를 예측하는 알고리즘을 수립하였다. 그 결과 70.6%의 성공률로 성과를 예측하여 다른 비교 대상 분석 방법과 분명한 차이를 보였다. 도출된 이벤트 성과 예측 정보는 이벤트를 준비하는 기관 및 업체에서 예상 수요량을 결정할 때 도움을 줄 수 있을 것이다.
