Detect Rumors Using Time Series of Social Context Information on Microblogging Websites
2015
Proceedings of the 24th ACM International on Conference on Information and Knowledge Management - CIKM '15
Preserved Fulltext
Our experiments using the events in two microblog datasets confirm that the method outperforms state-of-the-art rumor detection approaches by large margins. ...
Automatically identifying rumors from online social media especially microblogging websites is an important research issue. ...
We model microblog data as a set of events E = {Ei}, and each event Ei consists of relevant microblogs {mij }. ...

Rumors spread a large quantity of misinformation on microblogs. In this study we address two common issues within the context of microblog social media. ...
First we detect rumors as a type of misinformation propagation and next we go beyond detection to perform the task of rumor classification. WE explore the problem using a standard data set. ...
The most relevant related work to ours is that reported in [1] , which addresses rumor detection in Twitter using content-based as well as microblog-specific meme features. ...
