# Summary

UD EWT treebank is a converted version of the Estonian Web Treebank (EWT), originally annotated in the Constraint Grammar (CG) annotation scheme, and consisting of different genres of new media. The treebank contains 1,662 trees, 27,246 tokens.


# Introduction

The Estonian Web Treebank UD v2.4 is based on the subpart of [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 unedited new media texts.
