This paper introduces a tree generating system called Lexicalized Context-Free Grammar (LCFG) and describes a cubic-time parser for it. LCFG embeds the elegance of the analyses found in lexicalized tree-adjoining grammar without allowing for context-sensitive languages and therefore without requiring more computational resources than context-free grammars.
