IKM at SemEval-2017 Task 8: Convolutional Neural Networks for stance detection and rumor verification

This paper describes our approach for SemEval-2017 Task 8. We aim at detecting the stance of tweets and determining the veracity of the given rumor. We utilize a convolutional neural network for short text categorization using multiple filter sizes. Our approach beats the baseline classifiers on different event data with good F 1 scores. The best of our submitted runs achieves rank 1 st among all scores on subtask B.
