New parsing method removes arity actions, reduces action inventory

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel approach to non-binary bottom-up constituency parsing that eliminates the need for explicit arity actions. This new method separates the introduction of constituent labels from the reduction spans, deriving arity from the parser's state rather than specific action labels. Experiments on PTB and CTB datasets demonstrate that this delimiter-guided parser achieves competitive performance with existing arity-specific baselines while utilizing a significantly smaller action inventory.

IMPACT This research could lead to more efficient and compact natural language processing models by reducing the complexity of parsing actions.

    Non-binary bottom-up constituency parsing without arity actions

    arXiv:2607.10591v1 Announce Type: new Abstract: Non-binary bottom-up constituency parsing is usually taken to require arity actions: reductions such as \(\textsc{Reduce-}X\#k\) specify both the mother label and the number of children to be composed. We show that this arity parame…
