We investigate the use of a technique developed in the constraint programming community called constraint propagation to improve the efficiency of HPSG generation and parsing. Constraint propagation can make a HPSG theory more specific at those-previously (automatically) determined-places where linguistically motivated underspecification would lead to inefficient processing. We discuss two concrete HPSG examples showing how off-line constraint propagation helps improve processing efficiency.
