Summary

A Universal Dependencies treebank for Western Armenian was developed for UD originally by the ArmTDP team led by Marat M. Yavrumyan at the Yerevan State University.

Introduction

The UD_Western_Armenian-ArmTDP treebank is based on the Western Armenian part of the Հայերէնի Ծառադարան (ArmTDP v2.0) - a representative corpus of written Modern Standard Armenian covering a wide range of genres. The treebank consists of 6656 sentences (~122K tokens).

The annotation scheme was developed under the UD guidelines. The original data was manually annotated by the ArmTDP team. The tokenization and POS-tagging process involved alternating glossary-based automatic scripting and manual revision steps. The treebank is the only manually verified corpus of Western Armenian, supplied with comprehensive morphological and syntactic annotation in the form of a complete dependency tree for every sentence.

Acknowledgments

This work became possible through a research grant from the Calouste Gulbenkian Foundation («Գալուստ Կիւլպէնկեան» Հիմնարկութիւն) based in Lisbon, Portugal.
