2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/33240We propose a parser for constraint-logic grammars implementing HPSG that combines the advantages of dynamic bottom-up and advanced top-down control. The parser allows the user to apply magic compilation to specific constraints in a grammar which as a result can be processed dynamically in a bottom-up and goal-directed fashion. State of the art top-down processing techniques are used to deal with the remaining constraints. We discuss various aspects concerning the implementation of the parser as part of a grammar development system.9 pages, LaTeX with 4 postscript figures (uses avm.sty, eaclap.sty and psfig-scale.sty)Computation and LanguageI.2.7text
