| # Summary | |
| Swedish-PUD is the Swedish part of the Parallel Universal Dependencies (PUD) treebanks. | |
| # Introduction | |
| Swedish-PUD was created (together with the other parallel treebanks) for the CoNLL | |
| 2017 shared task on Multilingual Parsing from Raw Text to Universal Dependencies | |
| (http://universaldependencies.org/conll17/). It consists of Swedish translations | |
| of the 1000 sentences from the news domain and from Wikipedia, annotated according | |
| to the principles of the Swedish-PT treebank. The syntactic annotation has been | |
| manually validated, but the morphological annotation is automatically predicted. | |
| # Acknowledgments | |
| Translations were produced by Jacob Nolskog at Teknotrans AB and checked by Joakim | |
| Nivre. The automatic annotation was carried out using SwePipe, a tool suite trained | |
| on the Stockholm-Umeå Corpus and the Swedish-TP treebank, developed by Robert Östling, | |
| Aaron Smith and Joakim, and available from https://github.com/robertostling/efselab. | |
| The syntactic annotation was checked and corrected manually by Joakim Nivre. | |
| # PUD Treebanks | |
| 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 | |
| From v2.0 to v2.1, no changes have been made. | |
| From v2.1 to v2.2: | |
| - Harmonization with other Swedish treebanks: | |
| - Possessives retagged DET -> PRON | |
| - Negations ("inte", "icke", "ej") retagged ADV -> PART | |
| - Comparative markers ("som", "än") retagged CCONJ -> SCONJ | |
| - Comparative with nominal complement relabeled advcl -> obl [mark -> case, SCONJ -> ADP] | |
| - Clefts reanalyzed as copula constructions and relabeled acl:relcl -> acl:cleft | |
| - Temporal subordinating conjunctions ("när", "då") retagged ADV -> SCONJ and relabeled advmod -> mark | |
| - Added enhanced dependencies | |
| From v2.2 to v2.3: | |
| - Fixed a few errors in enhanced dependencies | |
| From v2.4 to v2.5 | |
| - Corrected morphological annotation (LEMMA, UPOS, XPOS, FEATS) | |
