Abstract

Derivations by a phrase-structure grammar may be represented by a word over the set of indices for the rules of the grammar. The set of all label words constitutes the label language for the grammar. The canonical label language is the restriction of the label language to the set of canonical derivations of the grammar. Whether a given language may be the label language for any grammar is partially answered by restricting the question to the canonical derivations for regular and contextfree grammars.
