  abstract = "Freer-word-order languages such as German exhibit linguistic phenomena that
              present unique challenges to traditional CFG parsing. Such phenomena produce 
              discontinuous constituents, which are not naturally modelled by projective phrase 
              structure trees. In this paper, we examine topological field parsing, a shallow
              form of parsing which identifies the major sections of a sentence in relation to
              the clausal main verb and the subordinating heads. We report the results of 
              topological field parsing of German using the unlexicalized, latent variable-based 
              Berkeley parser (Petrov et al., 2006). Without any language- or model-dependent
              adaptation, we achieve state-of-the-art results on the Tü Ba-D/Z corpus, and a
              modified NE-GRA corpus that has been automatically annotated with topological fields 
              (Becker and Frank, 2002). We also perform a qualitative error analysis of the parser 
              output, and discuss strategies to further improve the parsing results.",
