This resource is composed of 15.000 sentences taken from the German TIGER treebank that have been parsed using the Cheetah grammar for German (Cramer 2011) using the PET parser. The corpus consist of files containing Trees and MRS.

It contains syntactic and semantic representations of sentences and phrases. STTS tags from the original TIGER corpus are preserved in the Derivation Trees.

The structure of the data are TAB-delimited fields: ID, Derivation Tree, Tree, MRS.

The resource can only be accessed if the requester has a license for the original TIGER treebank.
