Summary

A Universal Dependencies treebank for Western Armenian 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 section of the Հայերէնի Ծառադարան dataset (ArmTDP v2.0), a broad-coverage corpus of general Modern Standard Armenian covering numerous genres. The treebank consists of 6656 sentences (~124K tokens).

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

Acknowledgments

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

The team behind the UD_Western_Armenian-ArmTDP: Marat M. Yavrumyan, Hrant H. Khachatrian, Anna S. Danielyan, Setrag H.M. Hovsepian, Liana G. Minasyan.
