Simple Open Stance Classification for Rumour Analysis
Table 2: Accuracy scores of different stance classifiers for the RumourEval dataset. The baseline is the best performing system in the SemEval evaluation Turing.
['[BOLD] Classifier', '[BOLD] All features', '[BOLD] w.o. AF']
The omission of the AF features leads to a performance decrease for all classifiers. The accuracy scores also fall below that of the SemEval winner Turing – the state-of-the-art system on the RumourEval dataset.
