Questions, comments? General annotation questions (either Slovenian-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 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 Slovenian UD Treebank is a rule-based conversion of the ssj500k treebank, the largest collection of manually syntactically annotated data in Slovenian, originally annotated in the JOS annotation scheme.

The Slovenian SSJ UD Treebank (Dobrovoljc et al. 2017) is based on the ssj500k treebank (Krek et al. 2019), a balanced collection of sampled texts from the FidaPLUS reference corpus of written Slovene (Arhar and Gorjanc 2007). The original ssj500k corpus has been manually segmented, tokenized, lemmatized and morphosyntactically tagged within JOS project, in which the annotation guidelines have also been developed (Erjavec et al. 2010). Additionally, approximately one half of the ssj500k treebank has been manually annotated for dependency relations, according to the JOS syntactic annotation scheme. The syntactically annotated part of the ssj500k corpus (known as ssj200k), consisting of 11,411 annotated sentences and 235,864 tokens, has been used as the basis for conversion to the Slovenian UD Treebank.

The conversion from ssj200k to the Slovenian SSJ UD Treebank was automatic (except for “biti”), based on a set of rules for both morphosyntactic and syntactic layer, which include different lexical, morphological and dependency features. The rules and conversion scripts are available at https://github.com/clarinsi/jos2ud

Due to the specifics of the original JOS syntactic annotation scheme, not all dependency relations from the original ssj200k treebank could be converted automatically, resulting in a smaller UD treebank size. The current version of the Slovenian UD Treebank thus contains 8,000 sentences with 140,670 tokens taken from various text types, e.g. fiction, non-fiction and periodicals, dating from 1990-2000. The original JOS annotations are included as part of the POSTAG (JOS morphosyntactic tags) and MISC (JOS dependency heads and labels) columns in the CONLLU format.

The corpus is linearly split into training (80%), development (10%) and test (10%) data.
