Parsing Bangla Grammar Using Context Free Grammar
, 2014 Parsing plays a very prominent role in computational linguistics. Parsing a Bangla sentence is a primary need in Bangla language processing. This chapter describes the Context Free Grammar (CFG) for parsing Bangla language, and hence, a Bangla parser is ...

Weighted omega-Restricted One Counter Automata [PDF]
Logical Methods in Computer Science, 2018 Let $S$ be a complete star-omega semiring and $\Sigma$ be an alphabet. For a weighted $\omega$-restricted one-counter automaton $\mathcal{C}$ with set of states $\{1, \dots, n\}$, $n \geq 1$, we show that there exists a mixed algebraic system over a ...

Multiplicative-Additive Focusing for Parsing as Deduction [PDF]
Electronic Proceedings in Theoretical Computer Science, 2015 Spurious ambiguity is the phenomenon whereby distinct derivations in grammar may assign the same structural reading, resulting in redundancy in the parse search space and inefficiency in parsing.

Syntactic Pattern Recognition for the Prediction of L-Type Pseudoknots in RNA
Applied Sciences, 2023 The observation and analysis of RNA molecules have proved crucial for the understanding of various processes in nature. Scientists have mined knowledge and drawn conclusions using experimental methods for decades.

On ordered context-free grammars
Information and Control, 1973 An extension for the concept of the finite index of context-free grammars is introduced and regular control languages are derived for the resulting family of languages generated by ordered context-free grammars.

FEBS Open Bio, EarlyView.Under environmental changes, the expression level of neuropeptide (NP) and neuropeptide receptor (NPR) genes changes to confer context‐dependent adaptation to the model organism Drosophila melanogaster. Through finding more regulatory elements in the NPR genes in comparison with their ligands (NPs), we found that NPR‐biased transcriptional regulation ...

3D Bioinspired Hair‐Based Solar Evaporator for Efficient Water Harvesting
Advanced Functional Materials, EarlyView.A bio‐derived solar evaporator inspired by blackbody radiation is developed using human hair waste. The vertically aligned hair structure enables broadband light absorption, efficient thermal localization, and rapid water transport, achieving high evaporation rates and stable desalination performance.

On Intuitionistic Fuzzy Context-Free Languages
Journal of Applied Mathematics, 2013 Taking intuitionistic fuzzy sets as the structures of truth values, we propose the notions of intuitionistic fuzzy context-free grammars (IFCFGs, for short) and pushdown automata with final states (IFPDAs).

An Augmented Context Free Grammar for Discourse
International Conference on Computational Linguistics, 1988 This paper presents an augmented context free grammar which describes important features of the surface structure and the semantics of discourse in a formal way, integrating new as well as previously existing insights into a unified framework.

A universal context-free grammar
Information and Control, 1975 In this report we show that, for each alphabet Σ, there exists a context-free grammar G which satisfies the property that for each context-free language L ⊆ Σ* a regular control set C can be found such that LC(G) = L.
