Abstract

Scattered context generators derive their sentences followed by the corresponding parses. This paper discusses their two canonical versions, which make this derivation either in a leftmost or rightmost way. It demonstrates that for every recursively enumerable language, L, there exists a canonical scattered context generator whose language consists of L's sentences followed by their parses. In fact, this result is established based on the generators containing no more than six nonterminals.
