Evaluating Induced CCG Parsers on Grounded Semantic Parsing
Yonatan Bisk, Siva Reddy, John C. Blitzer, Julia Hockenmaier, Mark J. Steedman · 2016
We compare the effectiveness of four different syntactic CCG parsers for a semantic slotfilling task to explore how much syntactic supervision is required for downstream semantic analysis.This extrinsic, task-based evaluation also provides a unique window into the semantics captured (or missed) by unsupervised grammar induction systems.
