Characterization and Topological Behavior of Homomorphism Tree-Shifts
Jung-Chao Ban, Chih-Hung Chang, Wen-Guei Hu +2
The purpose of this article is twofold. On one hand, we reveal the equivalence of shift of finite type between a one-sided shift and its associated hom tree-shift $\mathcal{T}_…
Topologically Mixing Properties of Multiplicative Integer System
Jung-Chao Ban, Chih-Hung Chang, Wen-Guei Hu +2
Motivated from the study of multiple ergodic average, the investigation of multiplicative shift spaces has drawn much of interest among researchers. This paper focuses on the relat…
Decidability of irreducible tree shifts of finite type
Jung-Chao Ban, Chih-Hung Chang, Nai-Zhu Huang +1
We reveal an algorithm for determining the complete prefix code irreducibility (CPC-irreducibility) of dyadic trees labeled by a finite alphabet. By introducing an extended directe…
UHop: An Unrestricted-Hop Relation Extraction Framework for Knowledge-Based Question Answering
Zi-Yuan Chen, Chih-Hung Chang, Yi-Pei Chen +2
In relation extraction for knowledge-based question answering, searching from one entity to another entity via a single relation is called "one hop". In related work, an exhaustive…
Complexity of Shift Spaces on Semigroups
J. C. Ban, C. H. Chang, Y. Z. Huang
Let be a semigroup with generating set and equivalences among determined by a matrix . This paper investigates the comple…
On the topological entropy of subshifts of finite type on free semigroups
Jung-Chao Ban, Chih-Hung Chang
In this paper, we provide an effective method to compute the topological entropies of -subshifts of finite type (-SFTs) with and , the free group and free se…
