Weighted omega-Restricted One Counter Automata [PDF]
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 ...

Evaluating two methods for Treebank grammar compaction [PDF]
Treebanks, such as the Penn Treebank, provide a basis for the automatic creation of broad coverage grammars. In the simplest case, rules can simply be ‘read off’ the parse-annotations of the corpus, producing either a simple or probabilistic context-free

Abstract Aim Nurse leaders influence workplace culture; however, little is known about ethnic cultural influences on nurse leader development. This research aims to identify personal strategies promoting effective leadership by nurse leaders from European small island countries. Design Descriptive qualitative study.

Multiplicative-Additive Focusing for Parsing as Deduction [PDF]
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.

Technology supports in the UDL framework: Removable scaffolds or permanent new literacies?
ABSTRACT Sharing multiliteracies goals of equitable access to educational success, the Universal Design for Learning (UDL) framework includes the use of contemporary technology tools, or new literacies, to customize ways to access information and processes and to construct and communicate knowledge. UDL also positions technology as a scaffold.

On Decidability and Expressive Power of Fusion Grammars [PDF]
We prove decidability of the non-emptiness problems for fusion grammars and decidability of the membership problem for fusion grammars without markers and connectors. Additionally, we prove the Parikh theorem for connection-preserving fusion grammars.

Obtaining valuable clues for noncoding RNA (ribonucleic acid) subsequences remains a significant challenge, acknowledging that most of the human genome transcribes into noncoding RNA parts related to unknown biological operations.

VLGrammar: Grounded Grammar Induction of Vision and Language [PDF]
Cognitive grammar suggests that the acquisition of language grammar is grounded within visual structures. While grammar is an essential representation of natural language, it also exists ubiquitously in vision to represent the hierarchical part-whole structure. In this work, we study grounded grammar induction of vision and language in a joint learning

On multiple context-free grammars
AbstractMultiple context-free grammars (mcfg's) is a subclass of generalized context-free grammars introduced by Pollard (1984) in order to describe the syntax of natural languages. The class of languages generated by mcfg's (called multiple context-free languages or, shortly, mcfl's) properly includes the class of context-free languages and is ...
