Anti-Context-Free languages

open access: yesJ. Autom. Lang. Comb., 2023
Context-free languages can be characterized in several ways. This article studies projective linearisations of languages of simple dependency trees, i. e., dependency trees in which a node can govern at most one node with a given syntactic function. We prove that the projective linearisations of local languages of simple dependency trees coincide with ...

The FC-rank of a context-free language [PDF]

open access: yesInformation Processing Letters, 2012
We prove that the finite condensation rank (FC-rank) of the lexicographic ordering of a context-free language is strictly less than @w^@w.

On Parsing Programming Languages with Turing-Complete Parser

open access: yesMathematics, 2023
A new parsing method based on the semi-Thue system is described. Similar to, but with more efficient implementation than Markov normal algorithms, it can be used for parsing any recursively enumerable language.

Complexity of Problems of Commutative Grammars [PDF]

open access: yesLogical Methods in Computer Science, 2015
We consider commutative regular and context-free grammars, or, in other words, Parikh images of regular and context-free languages. By using linear algebra and a branching analog of the classic Euler theorem, we show that, under an assumption that the ...

Evaluating Interactive Language for Children with Autism Spectrum Disorder (ASD) in Different Contexts

open access: yesChildren, 2022
Autism spectrum disorder (ASD) is characterized by impairments in the use of appropriate interactive language (including structural language and pragmatic skills) in social contexts.

Context-Free Languages, Coalgebraically [PDF]

open access: yes, 2011
We give a coalgebraic account of context-free languages using the functor D(X) = 2 × XA for deterministic automata over an alphabet A, in three different but equivalent ways: (i) by viewing context-free grammars as D-coalgebras; (ii) by defining a format for behavioural differential equations (w.r.t.

Partial Word Order Syntax of Urdu/Sindhi and Linear Specification Language

open access: yesJISR Management and Social Sciences & Economics, 2007
Like most of the South-Asian languages Urdu and Sindhi are partial word order languages. Conventional syntax representation models like Context Free Grammars are not capable enough to cope with partial word order syntax.

Towards a Context-Free Machine Universal Grammar (CF-MUG) in Natural Language Processing

open access: yesIEEE Access, 2020
In natural language processing, semantic document exchange ensures unambiguity and shares the same meaning for documents sender and receiver cross different natural languages (e.g., English to Chinese), this difference makes the translation between ...

THE LIMITS OF THE FORMAL TREATMENT OF LANGUAGE

open access: yesStudia Universitatis Babeș-Bolyai. Philosophia, 2019
The Limits of the Formal Treatment of Language. Within the philosophy of language, there is a distinction between the natural language philosophers and the ideal language philosophers. The distinction is drawn based on the way these philosophers reflect

KONTRIBUSI BAHASA ARAB TERHADAP BAHASA INDONESIA

open access: yesHunafa: Jurnal Studia Islamika, 2005
The development of a language is not free from the influences of other languages. For example, as an official language, Indonesian language used by Indonesians, is not free from the influences of other languages, either local languages such as  Javanese ...
