We present a richly annotated and genre-diversified language resource, the Prague Dependency Treebank-Consolidated 1. 0 (PDT-C 1. 0), the purpose of which is - as it always been the case for the family of the Prague Dependency Treebanks - to serve both as a training data for various types of NLP tasks as well as for linguistically-oriented research.

The motivation for the task is to extend a verbal valency (i. e., predicate-argument) lexicon by adding nouns that share the valency properties with the base verb, assuming their properties can be derived (even if not trivially) from the underlying verb by deterministic grammatical rules.
