We descrlbe a general parsing method for systemic gram- mars. Systemic grammars contain a paradigmatic analysis of language in addition to structural information, so a parser must assign a set of grammatical features and functions to each constituent in addition to producing a constituent struc- ture. Our method constructs a parser by compiling systemic grammars into the notation of Functional Unification Gram- mar. The existing methods for parsing with unification gram- mars hace been extended to handle a fuller range of paradig- matic descriptions. In particular, the PATR-II system has been extended by using disjunctive and conditional information in functional descriptions that are attached to phrase structure rules. The method has been tested with a large grammar of En- glish w:hich wa...
