Rumor Detection on Twitter Pertaining to the 2016 U.S. Presidential Election

The 2016 U.S. presidential election has witnessed the major role of Twitter in the year’s most important political event. Candidates used this social media platform extensively for online campaigns. Millions of voters expressed their views and voting preferences through following and tweeting. Meanwhile, social media has been filled with fake news and rumors, which could have had huge impacts on voters’ decisions. In this paper, we present a thorough analysis of rumor tweets from the followers of two presidential candidates: Hillary Clinton and Donald Trump. To overcome the difficulty of labeling a large amount of tweets as training data, we first detect rumor tweets by matching them with verified rumor articles. To ensure a high accuracy, we conduct a comparative study of five rumor detection methods. Based on the most effective method which has a rumor detection precision of 94.7%, we analyze over 8 million tweets collected from the followers of the two candidates. Our results provide answers to several primary concerns about rumors in this election, including: which side of the followers posted the most rumors, who posted these rumors, what rumors they posted, and when they posted these rumors. The insights of this paper can help us understand the online rumor behaviors in American politics.
