This paper presents an implemented hybrid approach to grammar and style checking, combining an industrial patternbased grammar and style checker with bidirectional, large-scale HPSG grammars for German and English.
the combination of shallow and deep components, hybrid processing, has already been investigated in several modular architectures, such as GAtE (Gaizauskas et al., 1996), Whiteboard (Crysmann et al., 2002) and Heart-of-Gold (Callmeier et al., 2004).
