As HPSG is head-driven, with clear semantic heads, semantic head-driven generation should be simple. We adapt van Noord's Prolog generator for use with an HPSG grammar in ProFIT. However, quantifiers and context factors are difficult to include in headdriven generation. We must adopt recent theoretical proposals for lexicalized scoping and context. With these revisions, head-driven generation with HPSG is not so simple, but it is possible.
