Following some previous studies on restarting automata, we introduce a refined model - the h-lexicalized restarting automaton (h-RLWW). We argue that this model is useful for expressing lexicalized syntax in computational linguistics. We compare the

Here we establish and study some rigorous tools suitable for the lexicalized syntactic analysis (LSA) of natural and formal languages. Motivated by the linguistic method of analysis by reduction, we are interested in correctness preserving LSA. We in

We analyze the computational power of discrete-time recurrent neural networks (NNs) with the saturated-linear activation function within the Chomsky hierarchy. This model restricted to integer weights coincides with binary-state NNs with the Heavisid

In natural languages with a high degree of word-order freedom, syntactic phenomena like dependencies (subordinations) or valences do not depend on the word-order (or on the individual positions of the individual words). This means that some permutati

Restarting automata can be seen as analytical variants of classical automata as well as of regulated rewriting systems. We study a measure for the degree of nondeterminism of (context-free) languages in terms of deterministic restarting automata that

Restarting automata can be considered as a machine model as well as regulated rewriting systems. We introduce a measure of ambiguity for restarting automata which recognizes a language as a projection of its characteristic language (containing also a

The $\mathsf{R}$-automaton is the weakest form of the nondeterministic version of the restarting automaton that was introduced by Jancar et al. to model the so-called analysis by reduction. Here it is shown that the class ℒ(R) of languages that are

In the literature various notions of monotonicity for restarting automata have been studied. Here we introduce two new variants of monotonicity for restarting automata and for two-way restarting automata: left-monotonicity and right-left-monotonicity

The t-contextual grammars are generalizations of Marcus contextual grammars, which insert t contexts in each derivation step. If the selection mappings are regular and satisfy an additional locality restriction, then these grammars correspond in thei

The paper provides linguistic observations as a motivation for a formal study of an analysis by reduction. It concentrates on a study of the whole mechanism through a class of restarting automata with meta-instructions using pebbles, with delete and
