Combining Lexicon-Driven Parsing and Phrase-Structure-Based Parsing

摘要

Lexicon-driven formalisms (e.g. Categorial Grammar, HPSG and GB Grammar), which do not have explicit phrase structure rules, are suitable for higher level syntax but not for low level language-specific constructions such as dates (July 15th, 15-JUL-1987, etc), which seem to require the power of phrase structure rules. This paper presents an Implementation method to combine lexicon-driven parsing and phrase structure parsing, with a special means called graph-structured stack.
