Description	Restarting automata can be seen as analytical variants of classical automata as well as of regulated rewriting systems. We study some measures for the degree of nondeterminism of (context-free) languages in terms of lexicalized deterministic restarting automata. These measures are based on the number of auxiliary symbols (categories) used for recognizing a language as the projection of its characteristic language onto its input alphabet. This type of recognition is typical for analysis by reduction, a method used in linguistics for the creation and verification of formal descriptions of natural languages. Our main results establish a two-dimensional hierarchy of classes of (context-free) languages based on the expansion factor of a language and on the number of different auxiliary symbols available in the underlying characteristic language.
