# Summary
The Slovak UD treebank is based on data originally annotated as part of the
Slovak National Corpus, following the annotation style of the Prague
Dependency Treebank.
# Introduction
Slovak Dependency Treebank (Slovenský závislostný korpus) was created as part
of the Slovak National Corpus at the Ľ. Štúr Institute of the Slovak Academy of
Sciences. The original annotation follows the guidelines of the Prague
Dependency Treebank (Czech), slightly modified in the spirit of Slovak
grammatical tradition. Morphological tags, lemmas and dependency relations have
been assigned manually to every word.
The present dataset is a subset of the original treebank. We automatically
selected the sentences where the two human annotators 100% agreed on the
analysis. This increases the quality and trustworthiness of the data but it
also results in selecting short sentences most of the time. An extended version
may be published in the future when manually merged and checked annotation is
available.
This subset annotated in the original PDT-like style is available separately,

UD_Slovak contains the same data with annotation converted to conform to the
Universal Dependencies guidelines. The original treebank was prepared by a team
led by Katarína Gajdošová and Mária Šimková. Selection of sentences for this
subset and conversion to Universal Dependencies was done by Dan Zeman.

# Changelog:
* 2020-05-15 v2.6
* Changed sentence ids to preserve the name of the source text.
* Side effect: The order of the sentences changed, and so did the train-dev-test data split.
* Genitive, dative and instrumental nominals are now considered oblique.
* Added enhanced relations with case information.
* Added enhanced relations around relative clauses.
* Added enhanced external subjects in control verb constructions.
* Added empty nodes to enhanced graphs (but orphans are just converted to dep).
* 2019-05-15 v2.4
* Fixed some bugs identified by the new validator.
* 2018-04-15 v2.2
* Repository renamed from UD_Slovak to UD_Slovak-SNK.
* Added enhanced representation of dependencies propagated across coordination.
The distinction of shared and private dependents is derived deterministically from the original Prague annotation.
* 2017-11-15 v2.1
* Prepositional objects are now “obl:arg” instead of “obj”.
* Instrumental phrases for demoted agents in passives are now “obl:agent”.
* 2017-03-01 v2.0
* Converted to UD v2 guidelines.
* Improved advmod vs. obl distinction.
* Verb negation no longer treated as derivational morphology.
* Distinguished numeral types.
* Distinguished pronouns, determiners and pronominal adverbs.
* Distinguished coordinating and subordinating conjunctions.
* L-participles are verbs, other participles are adjectives.
