Abstract

We describe an incremental parser which annotates grammatical functions in German on top of a shallow annotation structure consisting of chunks, topological fields and clauses. Since grammatical functions in German are strongly associated with case, the assignment and disambiguation of morphological information plays a crucial role as a step towards the annotation of grammatical functions. All components of the parsing system rely on finite-state methods to ensure efficient annotation. All stages of the annotation are robust so that they can deal with unexpected input from the source text or failing intermediate annotation components.
