In general, the base-line, that reaches an accuracy of 68.5%, is largely outperformed by the two models.
the base-line classifies events following this simple algorithm: • if the event is in a future tense, then the factuality value is IND • else, if the event is preceeded in the sentence by some negative word, then the factuality value is NR • else, the factuality value is R for IND events the base-line reaches just a 33.6% of F-Measure.
