We then manually inspect the sample and record whether or not the annotators' choices of different insertion points give rise to sentences with different semantic meaning or simply to sentences with different discourse structure.
we consider three categories for the observed disagreements: 1) the sentences are meaning equivalent from a truth-conditional perspective, 2) the sentences contain significant differences in meaning from a truth-conditional perspective, or 3) the sentences contain minor differences or ambiguities in meaning (but would likely be considered equivalent from the point of view of most readers).
