Table 2 Statistics of the corpus in terms of the number of abstracts per label. We present statistics for all labels (cf. 3.1), rounds of annotation (cf. 3.3) and when considering all annotations (All, left side) or only the one for which two annotators agree (Agree, right side). The comparison for the rounds in terms of equality (=), increase (\(\bigtriangleup\)), or decrease (\(\bigtriangledown\)) is with respect to the previous column (round), i.e. after the addition of the corresponding round. The values do not include duplicates, i.e. a label is only counted once if there is an agreement for it
