Abstract

We introduce the concept of fragmentation in order to adapt the learnability of regular languages towards other regular and nonregular language families. More precisely, rational transducers can be used to implement explicit fragmentation to define new identifiable regular language classes. Context conditions can be used to construe identifiable and characterizable language classes which may contain nonregular languages by means of implicit fragmentation.
