This article collects notes on reading and reproducing (part of) Silberer and Frank (2012).
Footnote 2: "The phrase type must be NPB, S, VP, SBAR, or SG." According to this list:
- S: "simple declarative clause, i.e. one that is not introduced by a (possibly empty) subordinating conjunction or a wh-word and that does not exhibit subject-verb inversion."
- VP: "verb Phrase"
- SBAR: "Clause introduced by a (possibly empty) subordinating conjunction"
"a preprocessing step is taken wherein NP brackets that do not dominate any other non-possessive NP nodes are relabeled as NPB. For consistency, an extra NP bracket is inserted around NPB nodes not already dominated by an NP. These NPB nodes are removed before evaluation. An example of this transformation can be seen here:"
"... sentences with and without subjects appear in quite different syntactic environments. For these reasons we modify the nonterminal for sentences without subjects to be SG"Evaluation metric: "We adopt the precision (P), recall (R) and F1 measures in Ruppenhofer et al. (2010)."
