Constraints in contact: Animacy in English and Afrikaans genitive variation – a cross-linguistic perspective

open access: yesGlossa, 2017
This paper builds on the observation that the animacy effects we find in English genitive variation are part of a larger cross-linguistic pattern as reflected in possession splits based on animacy (Koptjevskaja-Tamm 2001, 2002; Stolz et al.

Counting, generating and sampling tree alignments [PDF]

open access: yes, 2016
Pairwise ordered tree alignment are combinatorial objects that appear in RNA secondary structure comparison. However, the usual representation of tree alignments as supertrees is ambiguous, i.e.

Lexicalization of probabilistic grammars [PDF]

open access: yesProceedings of the 19th international conference on Computational linguistics -, 2002
Two general methods for the lexicalization of probabilistic grammars are presented which are modular, powerful and require only a small number of parameters. The first method multiplies the unlexicalized parse tree probability with the exponential of the mutual information terms of all word-governor pairs in the parse.

Making sense of syntax – Innate or acquired? Contrasting universal grammar with other approaches to language acquisition

open access: yesJournal of European Psychology Students, 2012
Proponents of a Universal Grammar argue that humans are born with a dedicated language system that shapes and restricts the number of grammars found in human languages (Chomsky, 2005). It is essentially innate and has a genetic manifestation.

Consistent Unsupervised Estimators for Anchored PCFGs

open access: yesTransactions of the Association for Computational Linguistics, 2020
Learning probabilistic context-free grammars (PCFGs) from strings is a classic problem in computational linguistics since Horning ( 1969 ). Here we present an algorithm based on distributional learning that is a consistent estimator for a large class of ...

Fuzzing With Optimized Grammar-Aware Mutation Strategies

open access: yesIEEE Access, 2021
Fuzzing is a widely used technique to discover vulnerabilities in software. However, for programs requiring highly structured inputs, the byte-based mutation strategies in existing fuzzers have difficulties in generating valid inputs.

A fine grained heuristic to capture web navigation patterns [PDF]

open access: yes, 2000
In previous work we have proposed a statistical model to capture the user behaviour when browsing the web. The user navigation information obtained from web logs is modelled as a hypertext probabilistic grammar (HPG) which is within the class of regular

Fuzzy Testing of Language Interpreter Based on Improved PCFG [PDF]

open access: yesJisuanji gongcheng, 2019
In order to construct samples that conform to language norms in fuzzy testing of language interpreter,and get abnormal test results as far as possible to find vulnerabilities,the improved Probabilistic Context Free Grammar(PCFG) model is used to control ...

Learning Analytics - Scientific Description and Heuristic Validation of Languages NLG

open access: yesJe-LKS: Journal of E-Learning and Knowledge Society, 2019
Educators do not have to be mere "Translators" as manufacturers of algorithms for teaching in the infosphere, but must modulate it for everyone's purposes.

Evolutionary triplet models of structured RNA. [PDF]

open access: yesPLoS Computational Biology, 2009
The reconstruction and synthesis of ancestral RNAs is a feasible goal for paleogenetics. This will require new bioinformatics methods, including a robust statistical framework for reconstructing histories of substitutions, indels and structural changes ...
