Error Analysis for Vietnamese Dependency Parsing
Table XI: Accuracy of root relation.
['[BOLD] Root relation', '[BOLD] Percentage', '[BOLD] Accuracy  [BOLD] MST', '[BOLD] Accuracy  [BOLD] Malt']
We consider precision and recall for dependents of the root node (mostly verbal predicate, noun predicate, and adjective predicate), and for subjects and objects (direct objects and indirect objects). MSTParser has considerably better precision (and better recall) for the root, subject, and direct object relations, but MaltParser is better for indirect objects. As results of root distance, we seen that MSTParser is precise for root modifiers.
