On the Theory of Stochastic Automata

no code implementations26 Mar 2021 Merve Nur Cakir, Mehwish Saleemi, Karl-Heinz Zimmermann

The theory of discrete stochastic systems has been initiated by the work of Shannon and von Neumann.

On the decomposition of generalized semiautomata

no code implementations19 Apr 2020 Merve Nur Cakir, Karl-Heinz Zimmermann

Semi-automata are abstractions of electronic devices that are deterministic finite-state machines having inputs but no outputs.

On Stochastic Automata over Monoids

no code implementations4 Feb 2020 Karl-Heinz Zimmermann, Merve Nur Cakir

Stochastic automata over monoids as input sets are studied.

Inference in Graded Bayesian Networks

no code implementations23 Dec 2018 Robert Leppert, Karl-Heinz Zimmermann

By restricting the topological structure to graded networks, an inference algorithm for graded Bayesian networks will be established that evaluates the hidden random variables rank by rank and in this way yields the most probable states of the hidden variables.

Parameter Transfer across Domains for Word Sense Disambiguation

no code implementations RANLP 2017 Sallam Abualhaija, Nina Tahmasebi, Diane Forin, Karl-Heinz Zimmermann

Word sense disambiguation is defined as finding the corresponding sense for a target word in a given context, which comprises a major step in text applications.

Metaheuristic Approaches to Lexical Substitution and Simplification

no code implementations EACL 2017 Sallam Abualhaija, Tristan Miller, Judith Eckle-Kohler, Iryna Gurevych, Karl-Heinz Zimmermann

In this paper, we propose using metaheuristics{---}in particular, simulated annealing and the new D-Bees algorithm{---}to solve word sense disambiguation as an optimization problem within a knowledge-based lexical substitution system.

D-Bees: A Novel Method Inspired by Bee Colony Optimization for Solving Word Sense Disambiguation

no code implementations6 May 2014 Sallam Abualhaija, Karl-Heinz Zimmermann

Word sense disambiguation (WSD) is a problem in the field of computational linguistics given as finding the intended sense of a word (or a set of words) when it is activated within a certain context.
