Derivation "Trees" and Parallelism in Chomsky-Type Grammars

open access: bronzeTriangle, 2018
In this paper we discuss parallel derivations for context-free, contextsensitive and phrase-structure grammars. For regular and linear grammars only sequential derivation can be applied, but a kind of parallelism is present in linear grammars. We show that nite languages can be generated by a recursion-free rule-set.

The Parallelism Tradeoff: Limitations of Log-Precision Transformers [PDF]

open access: yesTransactions of the Association for Computational Linguistics, 2023
Despite their omnipresence in modern NLP, characterizing the computational power of transformer neural nets remains an interesting open question. We prove that transformers whose arithmetic precision is logarithmic in the number of input tokens (and ...

Parallel Hyperedge Replacement Grammars [PDF]

open access: yesarXiv, 2021
In 2018, it was shown that all finitely generated virtually Abelian groups have multiple context-free word problems, and it is still an open problem as to where to precisely place the word problems of hyperbolic groups in the formal language hierarchy.

Resolving conflicts with violable constraints: On the cross-modular parallelism of repairs

open access: yesGlossa, 2019
When grammatical constraints impose conflicting requirements on a linguistic expression, this conflict is often resolved by employing a repair operation.

The role of language in advocacy: An SFL analysis of Hanan Ashrawi’s speech on Palestinian rights

open access: yesCogent Arts & Humanities, 2023
The study aimed to examine the rhetorical and linguistic devices employed in one of Hanan Ashrawi’s speeches to support the Palestinian cause and promote her perspective. Based on the Systemic Functional Linguistics (SFL) framework, this paper identified

A Computational Framework to Study Hierarchical Processing in Visual Narratives. [PDF]

open access: yesCogn Sci
Abstract Theories of visual narrative comprehension have advocated for a hierarchical grammar‐based comprehension mechanism, but only limited work has investigated this hierarchy. Here, we provide a computational framework inspired by computational psycholinguistics to address hierarchy in visual narratives.

Language properties and Grammar of Parallel and Series Parallel Languages [PDF]

open access: yesarXiv, 2017
In this paper we have defined the language theoretical properties of Parallel languages and series parallel languages. Parallel languages and Series parallel languages play vital roles in parallel processing and many applications in computer programming.

Associative Operator Precedence Parsing: A Method To Increase Data Parsing Parallelism

open access: yesInternational Conference on High Performance Computing in Asia-Pacific Region, 2023
Many data often come with a high volume in textual format (JSON, XML, CSV). Because parsing can easily dominate data analysis time, researchers have been working on parallelizing parsing. Operator Precedence Parsing (OPP), among candidate parsing methods,
