Abstract

This paper describes our system submitted to SemEval 2019 Task 7: RumourEval
2019: Determining Rumour Veracity and Support for Rumours, Subtask A (Gorrell et
al., 2019). The challenge focused on classifying whether posts from Twitter and
Reddit support, deny, query, or comment a hidden rumour, truthfulness of which is
the topic of an underlying discussion thread. We formulate the problem as
a stance classification, determining the rumour stance of a post with respect to
the previous thread post and the source thread post. The recent BERT architecture
was employed to build an end-to-end system which has reached the F1 score of
61.67 % on the provided test data. Without any hand-crafted feature, the system
finished at the 2nd place in the competition, only 0.2 % behind the winner.
