Typed feature grammars can be used as the basis for implementations of Head-driven Phrase Structure Grammar ( HPSG ; Pollard and Sag , 1994 ) as discussed in ( Gotz and Meurers , 1997a ) and ( Meurers and Minnen , 1997 ) .

In this paper we investigate the selective application of magic to typed feature grammars a type of constraint-logic grammar based on Typed Feature Logic ( T r ; G6tz , 1995 ) . Typed feature grammars can be used as the basis for implementations of Head-driven Phrase Structure Grammar ( HPSG ; Pollard and Sag , 1994 ) as discussed in ( Gotz and Meurers , 1997a ) and ( Meurers and Minnen , 1997 ) . Typed feature grammar constraints that are inexpensive to resolve are dealt with using the top-down interpreter of the ConTroll grammar development system ( GOtz and Meurers , 1997b ) which uses an advanced search function , an advanced selection function and incorporates a coroutining mechanism which supports delayed interpretation .
