On universal partial words [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2017
A universal word for a finite alphabet $A$ and some integer $n\geq 1$ is a word over $A$ such that every word in $A^n$ appears exactly once as a subword (cyclically or linearly).

Recurrent Partial Words [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2011
Partial words are sequences over a finite alphabet that may contain wildcard symbols, called holes, which match or are compatible with all letters; partial words without holes are said to be full words (or simply words). Given an infinite partial word w,

Effects of word length, contextual support, and prior second language proficiency on the learning of technical words in a second language. [PDF]

open access: yesPLoS ONE
Second language (L2) learners often struggle with learning technical words in a new discipline. Previous studies suggested that word length and context may differentially affect orthographic and semantic acquisition during initial L2 word learning.

Inference of partial colexifications from multilingual wordlists

open access: yesFrontiers in Psychology, 2023
The past years have seen a drastic rise in studies devoted to the investigation of colexification patterns in individual languages families in particular and the languages of the world in specific.

Equations on partial words [PDF]

open access: yesRAIRO - Theoretical Informatics and Applications, 2006
Summary: It is well-known that some of the most basic properties of words, like the commutativity \((xy = yx)\) and the conjugacy \((xz = zy)\), can be expressed as solutions of word equations. An important problem is to decide whether or not a given equation on words has a solution.

To some structural properties of ∞ - languages

open access: yesRatio Mathematica, 2022
Properties of catenation of sequences of finite (words) and infinite (  lengths are largely studied in formal language theory. These operations are derived from the mechanism how they are accepted or generated by the corresponding devices.

Unavoidable Sets of Partial Words of Uniform Length [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2017
A set X of partial words over a finite alphabet A is called unavoidable if every two-sided infinite word over A has a factor compatible with an element of X.

Dyck Words, Lattice Paths, and Abelian Borders [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2017
We use results on Dyck words and lattice paths to derive a formula for the exact number of binary words of a given length with a given minimal abelian border length, tightening a bound on that number from Christodoulakis et al.

Entailment Relations on Distributions [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2016
In this paper we give an overview of partial orders on the space of probability distributions that carry a notion of information content and serve as a generalisation of the Bayesian order given in (Coecke and Martin, 2011).
