Off-line Constraint Propagation for Efficient HPSG Processing
We investigate the use of a technique developed in the constraint programming
community called constraint propagation to automatically make a HPSG theory
more specific at those 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.Comment: 10 pages, uuencoded gzipped Postscrip
