Abstrakt
We build a large treebank of Czech, avoiding manual effort by using a parser, supplemented by a rule-based correction tool. A potentially underspecified morphological and syntactic annotation scheme offers multiple visualisation and export options, customizable in shape and detail according to the preferences of humans or computer applications.
The annotation scheme consists of three layers: graphemics, morphology and constituency-based syntax, and is supported by a lexicon (with a morphological, multi-word and syntactic part) and a grammar. Annotation on any of the interlinked layers can be missing; ambiguous or undecidable phenomena are represented by underspecification and distributive disjunction.
