=================================== Universal Dependency Treebanks v2.0

This directory contains treebanks for the following languages: English, German, French, Spanish, Swedish, Korean, Japanese, Indonesian, Brazilian Portuguese, Italian and Finnish.

A description of how the treebanks were generated can be found in:

Universal Dependency Annotation for Multilingual Parsing Ryan McDonald, Joakim Nivre, Yvonne Quirmbach-Brundage, Yoav Goldberg, Dipanjan Das, Kuzman Ganchev, Keith Hall, Slav Petrov, Hao Zhang, Oscar Tackstrom, Claudia Bedini, Nuria Bertomeu Castello and Jungmee Lee Proceedings of ACL 2013

A more detailed description of each relation type in our harmonized scheme is included in the file universal-guidelines.pdf.

Each treebank has been split into training, development and testing files.

Each file is formatted according to the CoNLL 2006/2007 guidelines:

http://ilk.uvt.nl/conll/#dataformat

The treebank annotations use basic Stanford Style dependencies, modified minimally to be sufficient for each language and be maximally consistent across languages. The original English Stanford guidelines can be found here:

============================================================================== Version 2.0 - What is new

  1. Added more data for German, Spanish and French.
  2. Added Portuguese Brazilian, Indonesian, Japanese, Italian and Finnish.
  3. New content-head versions for 5 languages (see below).
  4. A number of bug fixes in the harmonization process.

===================== Standard dependencies

In release 2.0 we include two sets of dependencies. The first is standard Stanford dependencies, which correspond roughly to the output of the Stanford converter for English with the copula as head set to true. In general, these are content-head dependency representations with two major exceptions: 1) adpositions are the head in adpositional phrases, and 2) copular verbs are the head in copluar constructions.

This data is in the std/ directory and contains all languages but Finnish.

Version 1.0 of the data is only standard.

========================== Content head dependencies

In order to converge to a more uniform multilingual standard, in particular for morphologically rich languages, this release also includes a beta version of content-head dependencies for five languages: German, Spanish, Finnish, French and Swedish. Here the content word is always the head of a phrase.

============================================================================= Language Specific Information

==================== English dependencies

Note that the English dependencies are based on the original Penn Treebank data automatically converted with the Stanford Dependency Converter. Instructions for how to do this with corresponding scripts are included in the English directory.

==================== Finnish dependencies

Finnish data is in the ch/fi directory and was produced by researchers at the University of Turku. In that directory there are specific README and LICENSE files for that data. Two things to note. First, the Finnish data is only content-head. This is due to difficulties in automatically converting the data to standard format from its original annotations. Second, we have included a test set in the release, but this is not the real test set, just a subset of the training. The true test set for this data is blind (as per the wishes of the researchers at Turku). The unannotated test data is included as well as instructions for obtaining scores on predictions.

============================================================================= Other Information

================================ Fine-grained part-of-speech tags

In the CoNLL file format there is a coarse part-of-speech tag field (4) and a fine-grained part-of-speech tag field (5). In this data release, we use the coarse field to store the normalized universal part-of-speech tags that are consistent across languages. The fine-grained field contains potentially richer part-of-speech information depending on the language, e.g., a richer tag representation for clitics.

========================= Licenses and terms-of-use

For the following languages

German, Spanish, French, Indonesian, Italian, Japanese, Korean and Brazilian Portuguese

we will distinguish between two portions of the data.

  1. The underlying text for sentences that were annotated. This data Google asserts no ownership over and no copyright over. Some or all of these sentences may be copyrighted in some jurisdictions. Where copyrighted, Google collected these sentences under exceptions to copyright or implied license rights. GOOGLE MAKES THEM AVAILABLE TO YOU 'AS IS', WITHOUT ANY WARRANTY OF ANY KIND, WHETHER EXPRESS OR IMPLIED.

  2. The annotations -- part-of-speech tags and dependency annotations. These are made available under a CC BY-NC-SA 3.0 non commercial license. GOOGLE MAKES THEM AVAILABLE TO YOU 'AS IS', WITHOUT ANY WARRANTY OF ANY KIND, WHETHER EXPRESS OR IMPLIED. See attached LICENSE file for the text of CC BY-NC-SA.

Portions of the German data were sampled from the CoNLL 2006 Tiger Treebank data. Hans Uszkoreit graciously gave permission to use the underlying sentences in this data as part of this release.
