  1. Because nested and discontiguous (Discont.) entities are dealt with differently in our baseline experiments, we report numbers of “simple” annotations, i.e. those that are neither nested nor discontiguous. Nested and Discont. refers to annotations that are either nested or discontiguous. “Both N&D” refers to entities both nested and discontiguous. Every entity is only counted within its most specific type. An entity that appears several times is counted as many times it appears.
