| # Summary | |
| This is a part of the Parallel Universal Dependencies (PUD) treebanks created | |
| for the [CoNLL 2017 shared task on Multilingual Parsing from Raw Text to | |
| Universal Dependencies](http://universaldependencies.org/conll17/). | |
| # Introduction | |
| There are | |
| 1000 sentences in each language, always in the same order. (The sentence | |
| alignment is 1-1 but occasionally a sentence-level segment actually consists | |
| of two real sentences.) The sentences are taken from the news domain (sentence | |
| id starts in ‘n’) and from Wikipedia (sentence id starts with ‘w’). There are | |
| usually only a few sentences from each document, selected randomly, not | |
| necessarily adjacent. The digits on the second and third position in the | |
| sentence ids encode the original language of the sentence. The first 750 | |
| sentences are originally English (01). The remaining 250 sentences are | |
| originally German (02), French (03), Italian (04) or Spanish (05) and they | |
| were translated to other languages via English. Translation into German, | |
| French, Italian, Spanish, Arabic, Hindi, Chinese, Indonesian, Japanese, | |
| Korean, Portuguese, Russian, Thai and Turkish has been provided by DFKI and | |
| performed (except for German) by professional translators. Then the data has | |
| been annotated morphologically and syntactically by Google according to Google | |
| universal annotation guidelines; finally, it has been converted by members of | |
| the UD community to UD v2 guidelines. | |
| Additional languages have been provided (both translation and native UD v2 | |
| annotation) by other teams: Czech by Charles University, Finnish by University | |
| of Turku and Swedish by Uppsala University. | |
| The entire treebank is labeled as test set (and was used for testing in the | |
| shared task). If it is used for training in future research, the users should | |
| employ ten-fold cross-validation. | |
| # Changelog | |
| * 2017-11-15 v2.1 | |
| * First official release after it was used as a surprise dataset in the | |
| CoNLL 2017 shared task. | |
