English(EN) Non-binary bottom-up constituency parsing without arity actions

新的句法分析方法移除歧义动作，减少动作集

作者 PulseAugur 编辑部 · [1 个来源] · 2026-07-14 04:00

研究人员开发了一种新颖的非二元自底向上成分句法分析方法，无需显式的歧义动作。该新方法将成分标签的引入与规约跨度分开，从解析器的状态而非特定的动作标签中推导歧义。在PTB和CTB数据集上的实验表明，这种分隔符引导的解析器在利用显著更小的动作集的同时，实现了与现有歧义特定基线相当的性能。 AI

影响这项研究通过降低句法分析动作的复杂性，可能带来更高效、更紧凑的自然语言处理模型。

无需动作的非二元自下而上成分句法分析

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…
