Fake News and Related Concepts: Definitions and Recent Research Development

Fake news is an emerging field of research that attracts much attention from academic communities as well as mass media practitioners. However, the concept of fake news is still ambiguous, and the boundary between the definition of fake news and other relative concepts, such as news satire, yellow journalism, junk news, pseudo-news, hoax news, propaganda news, advertorial, false information, fake information, misinformation, disinformation, mal-information, alternative fact, and post-truth is blurred. The present study aims to identify the meanings of fake news and other related concepts, and explore the recent trend of research on them. By searching the journals listed in the Social Sciences Citation Index (SSCI) and Science Citation Index Expanded (SCI-Expanded) database, the present study found 387 articles on fake news. Through analyzing these articles, the present study maps the trend and reveals the highly influential research articles, as well as theories and concepts that are used. The results may provide fundamental insights into the development of research on fake news in recent years.
