We thus consider two path simplifications as well: • compressed: only the source, target, and root nodes are preserved in the path (so the path above becomes [VBP ↑ S ↓ NP]) • POS class clusters: rather than distinguish, for example, between different tenses of verbs in a path, we consider only the first letter of each NT.
clustering compressed output, the new path from predicate to ARG0 becomes The top paths were similarly consistent regardless of whether paths are extracted from P ra , P vm , or P va (P va results shown in Table 4), but we see that the distributions of paths are much flatter (i.e.
