Abstract

The Levenstein or edit distance was developed as a metric for calculating distances between character strings.We are looking at weighting the different edit operations (insertion, deletion, substitution) to obtain different types of classifications of sets of strings. As a more general and less constrained approach we introduce topological notions and in particular uniformities.
