초록

본 연구는 알츠하이머에 대한 의료 웹포럼 컨텐츠의 감성 분석과 사회연결망 분석을 연계하여 감성을 표현하는 정도와 사회연결망상의 영향력 사이의 관계를 살펴보았다. 최근 사회가 고령화가 됨에 따라 치매환자는 증가하고 있는데 이에 환자뿐만 아니라 환자 보호자들은 질병에 관한 정보뿐만 아니라 위로를 얻기 위하여 의료 웹포럼을 이용하고 있다. 웹포럼상에서의 정보적/감성적 지지의 형태로 나타나는 사회연결망을 분석한 결과, 네트워크 중앙에 위치한 사용자의 감성표출이 다른 사용자의 감성 표출보다 높게 나타나는 것을 관찰하였다. 또한 긍정적 단어를 많이 사용하는 그룹이 부정적 단어를 많이 사용하는 그룹에 비해 연결중심성 및 보나시치중심성 값이 높게 나타난 것을 확인할 수 있었다. 본 연구는 웹포럼 상의 감성전달에 있어서 일반 사용자에게 큰 영향력을 줄 수 있는 오피니언 리더를 도출하고, 알츠하이머 환자의 우울증을 완화할 수 있는 정책의 일환으로 활용할 수 있을 것이다.

In this study, we aim to analyze the relationship between the centrality in the social network and the sentiment of medial web forum users. In recent, many people use online resources to obtain health and wellness information especially social media resources. In the medial web forum, people give and receive informational supports and emotional supports and this interaction forms the social network. We analyze the social network, derive node characteristics in terms of centrality and compare the centrality index and the sentiment score derived from users' messages. We found that as more people express their emotion, they possess higher central position in the network. Further, people who express positive emotion in their messages have higher central position in the network than people who have negative emotion. This study will help to identify influentials of emotional supports to others and finally to control the depression of Alzheimer's disease patients and their related ones.
