Tokens are surface tokens (Spanish `vámonos` is one), words are syntactic words (`vamos` + `nos`); multiword tokens are those split into several words; empty nodes are the `N.M` nodes of the enhanced graph.

## Summary

> UD Estonian is a converted version of the Estonian Dependency Treebank (EDT), originally annotated in the Constraint Grammar (CG) annotation scheme, and consisting of genres of fiction, newspaper texts and scientific texts. The treebank contains 30,972 trees, 437,769 tokens.

## Introduction

> The Estonian UD EDT treebank is based on the [Estonian Dependency Treebank](https://github.com/EstSyntax/) (EDT), created at the University of Tartu. The treebank has been automatically converted and then manually reviewed and reannotated.
> 
> The treebank covers 3 different genres, namely newspaper texts, fiction and scientific texts:
> 
> - fiction (67,744 tokens, 5,522 sentences)
> - newspapers (266,806 tokens, 18,690 sentences)
> - scientific texts (94,022 tokens, 5,483 sentences)
> - Also, the subpart of Estonian part of HamleDT 3.0 treebank has been reannotated and included in the treebank; it contains 9,200 tokens in 1277 sentences.
> 
> In addition to standard ud annotation, annotation of named entiites has been added to MISC-field (NE=B-Type or NE=I-Type, there TYPE stands for PER (person), ORG (organisation), LOC (location), GEP (geopolitical name), EVENT (events), PROD (product), MUU (other) or UNK (unknown)).
> 
> Also, a preliminary argument structure has been annotated in the MISC field (Verb=meaning, Arg=verb_Arg_[0-5]).
