This environment currently supports tree-based grammars (namely Tree-Adjoining Grammars (TAG) and Multi-Component Tree-Adjoining Grammars with Tree Tuples (TT-MCTAG)) and allows computation not only of syntactic structures, but also of the corresponding semantic representations. It is used for the development of a tree-based grammar for German.

In previous efforts, such as PropBank, this process was aided with the help of syntactic trees, manually correcting automatically produced annotations. We argue that when using a lexicalised approach the annotation effort can be made simpler, avoiding the need to explicitly select two entities for each role. Our model is demonstrated by the Groningen Meaning Bank, using Combinatory Categorial Grammar as syntactic formalism, and Discourse Representation Theory as a formal semantic backbone.
