An evaluation of only sentences with coordination shows that there is a noticeable difference: the F-score reaches 67.28 (precision: 66.36%, recall: 68.23%) as compared to 69.73 for the full test set.
the F-score is also minimally higher than the F-score for experiment 2 (gold scope), and recall is increased by approximately 1 percent point (even though only 12.5% of the sentences were reranked).
