3 Pattern extraction and matching
After converting the Penn Treebank to a dependency
treebank, we first extracted non-local dependency
patterns. ... all non-local
patterns from the Penn Treebank, which resulted in
987 different (pattern, non-local dependency) pairs.
As described in Section 3, after cleaning up we took
