constituency-parsing

This paper proposes a delimiter-guided bottom-up constituency parser that removes the need for explicit arity actions by deriving arity from stack configurations, achieving competitive results on PTB and CTB with a smaller action inventory.

This paper introduces Holographic Neural PCFG (Hol-PCFG), which recasts probabilistic context-free grammar rule scoring using holographic embeddings, achieving state-of-the-art unsupervised parsing performance across six languages with a 99.94% reduction in parameters.
