Questions, comments? General annotation questions (either Greek-specific or cross-linguistic) can be raised in the main UD issue tracker. You can report bugs in this treebank in the treebank-specific issue tracker on Github. If you want to collaborate, please contact [prokopis (æt) ilsp • gr]. Development of the treebank happens outside the UD repository. If there are bugs, either the original data source or the conversion procedure must be fixed. Do not submit pull requests against the UD repository.

Description

The Greek UD treebank (UD_Greek-GDT) is derived from the Greek Dependency Treebank (http://gdt.ilsp.gr), a resource developed and maintained by researchers at the Institute for Language and Speech Processing/Athena R.C. (http://www.ilsp.gr).

The Greek UD treebank consists of 2,521 sentences (61,673 tokens). The data in the current release derive from primary texts that are in the public domain, including wikinews articles and european parliament sessions. The treebank is licensed under the terms of Creative Commons Attribution-NonCommercial-ShareAlike, CC BY-NC-SA 3.0.

The morphological and syntactic annotation of the Greek UD treebank was originally created through a semi-automatic conversion of PDT-style annotations in GDT data. The syntactic annotation of the 2.1 release was generated by manual corrections of several constructions of the UD annotation, which is now the only manual syntactic annotation used for new data added to the resource. The harmonization with UD v2 is work in progress.

Acknowledgments

We wish to thank all contributors to the original annotation efforts. A large part of those annotations was work by students of the postgraduate programme Technoglossia IV, organised by the Institute for Language and Speech Processing, the University of Athens and the National Technical University of Athens.
