Nested words are a concept proposed by Alur and Madhusudan as a joint generalization of words, as traditionally used for modelling linearly ordered structures.

Abstract. Nested words are a restriction of the class of visibly pushdown lan- guages that provide a natural model of runs of programs with recursive ...

What are nested words? Nested words is a model for representation of data with both a linear ordering and a hierarchically nested matching of items. Examples of ...

PDF | For every regular language of nested words, the underlying strings form a context-free language, and every context-free language can be obtained.

Nested words provide a natural model of runs of programs with recursive procedure calls. The usual connection between monadic second-order logic (MSO) and ...

For every regular language of nested words, the underlying strings form a context-free language, and every context-free language can be obtained in this way.

We propose nested words to capture models where there is both a natural linear sequencing of positions and a hierarchically nested matching of positions.

Abstract. Nested words are a structured model of execution paths in procedural pro- grams, reflecting their call and return nesting structure.

Nested words allow modeling of linear and hierarchical structure in data, and nested word automata are special kinds of pushdown automata whose push/pop ...
