A tree interpretation of arc standard dependency derivation
arXiv CS.CL
•
ArXi:2603.27459v1 Announce Type: new We show that arc-standard derivations for projective dependency trees determine a unique ordered tree representation with surface-contiguous yields and stable lexical anchoring. Each \textsc{shift}, \textsc{leftarc}, and \textsc{rightarc} transition corresponds to a deterministic tree update, and the resulting hierarchical object uniquely determines the original dependency arcs.
