A generation-oriented workbench for performance grammar: Capturing linear order variability in German and Dutch. In Proceedings of the 4th International Natural Language Generation Conference
We describe a generation-oriented workbench for the Performance Grammar (PG) formalism, highlighting the treatment of certain word order and movement constraints in Dutch and German. PG enables a simple and uniform treatment of a heterogeneous collection of linear order phenomena in
the domain of verb constructions (variably known as Cross-serial Dependencies, Verb Raising, Clause Union,
Extraposition, Third Construction, Particle Hopping, etc.). The central data structures enabling this feature are
clausal “topologies”: one-dimensional arrays associated with clauses, whose cells (“slots”) provide landing sites for the constituents of the clause. Movement operations are enabled by unification of lateral slots of topologies at adjacent
levels of the clause hierarchy. The PGW generator assists the grammar developer in testing whether the implemented syntactic knowledge allows all and only the well-formed permutations of constituents.
