Transition-based DRS Parsing Using Stack-LSTMs
Kilian Evang · 2019
We present our submission to the IWCS 2019 shared task on semantic parsing, a transitionbased parser that uses explicit word-meaning pairings, but no explicit representation of syntax.Parsing decisions are made based on vector representations of parser states, encoded via stack-LSTMs (Ballesteros et al., 2017), as well as some heuristic rules.Our system reaches 70.88% f-score in the competition.
