Varieties of Languages in a Category [PDF]
2015 30th Annual ACM/IEEE Symposium on Logic in Computer Science, 2015 Eilenberg's variety theorem, a centerpiece of algebraic automata theory, establishes a bijective correspondence between varieties of languages and pseudovarieties of monoids. In the present paper this result is generalized to an abstract pair of algebraic categories: we introduce varieties of languages in a category C, and prove that they correspond to

Proceedings of the Conference Recent Advances in Natural Language Processing - Deep Learning for Natural Language Processing Methods and Applications, 2021 Many organizations seek or need to produce documents that are written plainly. In the United States, the “Plain Writing Act of 2010” requires that many federal agencies’ documents for the public are written in plain English. In particular, the government’s Plain Language Action and Information Network (“PLAIN”) recommends that writers use short ...

On Varieties of Automata Enriched with an Algebraic Structure (Extended Abstract) [PDF]
Electronic Proceedings in Theoretical Computer Science, 2014 Eilenberg correspondence, based on the concept of syntactic monoids, relates varieties of regular languages with pseudovarieties of finite monoids. Various modifications of this correspondence related more general classes of regular languages with ...

Creole Prosodic Systems Are Areal, Not Simple
Frontiers in Psychology, 2021 This study refutes the common idea that tone gets simplified or eliminated in creoles and contact languages. Speakers of African tone languages imposed tone systems on all Afro-European creoles spoken in the tone-dominant linguistic ecologies of Africa ...

On logical hierarchies within FO^2-definable languages [PDF]
Logical Methods in Computer Science, 2012 We consider the class of languages defined in the 2-variable fragment of the first-order logic of the linear order. Many interesting characterizations of this class are known, as well as the fact that restricting the number of quantifier alternations ...
