The quick check pre-unification filter for typed grammars
Liviu Ciortuz · 2005
The so called quick check (henceforth QC) pre-unification filter for feature structure (FS) unification was introduced by (Kiefer et al., 1999). QC is considered the most important speed-up technique in the framework of non-compiled FS unification. We present two potential ways in which the design of the quick check can be further extended: consistency sort check on coreferenced paths, and pre-unification type-checking. We analyse the effect of these extensions on LinGO, the large-scale HPSG grammar for English (Flickinger et al., 2000) using the compiler system LIGHT (Ciortuz, 2002).
