The article will briefly introduce the Prague Dependency Treebank. In this treebank written Czech sentences are annotated on three layers: morphological layer (morphological categories), analytical layer (surface structure) and the tectogrammatical layer (deep structure).
We focus on how sentences are represented on the tectogrammatical layer. Main aim of this article is to suggest a detailed specification of meanings of spatial modifications for annotation on this layer.
This detailed specification of meanings of modifications represents necessary information for the translation from one language to another.
