초록

인터넷 및 모바일 기술의 발달과 소셜미디어의 확산으로 인해 다량의 정보들이 온라인 상에서 생성, 유통되고 있다. 이중에는 대중에게 도움이 되는 유익한 정보들도 있지만, 역기능을 하는 이른바 가짜뉴스들도 함께 유통되고 있다. 지난 2020년 코로나19의 전세계적인 확산 이후, 온라인 상에는 이와 관련한 수많은 가짜뉴스들이 유통되었다. 다른 가짜뉴스들과 달리 코로나19와 관련된 가짜뉴스는 사람들의 건강, 나아가 생명까지 위협할 수 있다는 점에서 그 심각성이 매우 크다고 할 수 있다. 때문에 코로나19와 관련한 가짜뉴스를 자동으로 탐지하고, 이를 예방하는 지능형 기술은 사회적 건강도를 제고하는데 매우 의미 있는 연구주제라 할 수 있다. 이러한 배경에서 본 연구에서는 코로나19 관련 가짜뉴스 탐지를 효과적으로 수행하기 위해 그래프 임베딩 방법 중 하나인 Graph2vec을 활용한 방법을 제안한다. 가짜뉴스 탐지에 대한 주류 방법은 뉴스 콘텐츠 기반 즉, 텍스트에 대한 특징 분석으로 진행되었으나 본 연구에서는 사회적 참여 네트워크 내에서의 정보 전달 관계를 추가로 활용함으로써 보다 효과적으로 코로나19와 관련된 가짜뉴스를 탐지할 수 있었으며 성능 측면에서 정확도 향상을 확인할 수 있었다.

With the development of Internet and mobile technology and the spread of social media, a large amount of information is being generated and distributed online. Some of them are useful information for the public, but others are misleading information. The misleading information, so-called 'fake news', has been causing great harm to our society in recent years. Since the global spread of COVID-19 in 2020, much of fake news has been distributed online. Unlike other fake news, fake news related to COVID-19 can threaten people's health and even their lives. Therefore, intelligent technology that automatically detects and prevents fake news related to COVID-19 is a meaningful research topic to improve social health. Fake news related to COVID-19 has spread rapidly through social media, however, there have been few studies in Korea that proposed intelligent fake news detection using the information about how the fake news spreads through social media. Under this background, we propose a novel model that uses Graph2vec, one of the graph embedding methods, to effectively detect fake news related to COVID-19. The mainstream approaches of fake news detection have focused on news content, i.e., characteristics of the text, but the proposed model in this study can exploit information transmission relationships in social engagement networks when detecting fake news related to COVID-19. Experiments using a real-world data set have shown that our proposed model outperforms traditional models from the perspectives of prediction accuracy.
