Independent parallelism in finite copying parallel rewriting systems
Owen Rambow,Giorgio Satta +1 more
TL;DR: It is shown that, when the degree of synchronized parallelism is bounded by some constant greater than one, thedegree of independent parallelism induces an infinite non-collapsing hierarchy within the family of generated languages.
Journal ArticleDOI
Mildly non-projective dependency grammar
TL;DR: This article presents a formalism for non-projective dependency grammar in the framework of linear context-free rewriting systems, and shows that parsing with unrestricted grammars is intractable, and defines a class of “mildly” non- projective dependency Grammars that can be parsed in polynomial time.
Implicit dynamic function introduction and Ackermann-like Function Theory
TL;DR: The paper is based on recollections of Grigori Mints completed by a survey of his research work in a scientific context and sometimes goes beyond the purely scientific aspects to show the atmosphere of these times.
A Two-Dimensional Hierarchy for Parallel Rewriting Systems
Owen Rambow,Giorgio Satta +1 more
TL;DR: The class of parallel rewriting systems is considered in this work and the interaction between two complexity measures that in the liter ature have been called synchronous parallelism and independent paral lelism is investigated.
Journal ArticleDOI
On the Complexity of CCG Parsing
TL;DR: It is proved that any parsing algorithm for this formalism will take in the worst case exponential time when the size of the grammar, and not only the length of the input sentence, is included in the analysis.
