BKTreebank: Building a Vietnamese Dependency Treebank

TL;DR

This paper introduces BKTreebank, a Vietnamese dependency treebank, detailing its design and demonstrating its usefulness through POS tagging and dependency parsing experiments, thereby advancing Vietnamese NLP resources.

Contribution

The paper presents the creation of BKTreebank, the first Vietnamese dependency treebank, including its annotation guidelines and experimental validation for NLP tasks.

Findings

POS tagging accuracy improved with the treebank

Dependency parsing results demonstrate the treebank's utility

Provides a foundational resource for Vietnamese NLP

Abstract

Dependency treebank is an important resource in any language. In this paper, we present our work on building BKTreebank, a dependency treebank for Vietnamese. Important points on designing POS tagset, dependency relations, and annotation guidelines are discussed. We describe experiments on POS tagging and dependency parsing on the treebank. Experimental results show that the treebank is a useful resource for Vietnamese language processing.
