Questions, comments? General annotation questions (either Polish-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 [aep (æt) ipipan • waw • pl, adamp (æt) ipipan • waw • pl]. 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.

Description

The LFG Enhanced UD treebank of Polish is based on a corpus of LFG (Lexical Functional Grammar) syntactic structures generated by an LFG grammar of Polish, POLFIE, and manually disambiguated by human annotators.

The treebank consists of around 17,200 sentences (see the Data Split section for precise numbers). Thanks to the richness of the original LFG representations, it makes heavy use of enhanced dependencies. Secondary edges are used not only in representations of coordination (for shared dependents and shared governors), but also for various control-like constructions.

The annotation differs from (the release 2.1 of) the SZ UD treebank of Polish also in other respects, including the following:

Acknowledgments

The original LFG corpus has been developed under the supervision of Agnieszka Patejuk (many thanks to the annotators!) and has been converted to UD by Adam Przepiórkowski, in collaboration with Agnieszka Patejuk. Both the creation of the original LFG corpus and the conversion into UD have been partially supported by the Polish Ministry of Science and Higher Education within the CLARIN ERIC programme 2015–2018 (http://clarin.eu/). The data, lemmata and original morphosyntactic tags come from the manually annotated subcorpus of the National Corpus of Polish (led by Adam Przepiórkowski; http://nkjp.pl/), whose development was financed by the Polish Ministry of Science and Higher Education in 2007–2011, and – to a lesser extent – from the corpus Polish language of the 1960s (http://clip.ipipan.waw.pl/PL196x). Many thanks to Joakim Nivre and Dan Zeman for their infinite patience in answering a myriad of diverse UD-related questions during the development of this treebank.
