Metric Lexical Analysis

We study automata-theoretic properties of distances and quasi-distances between words. We show that every additive distance is finite. We also show that every additive quasi-distance is regularity-preserving, that is, the neighborhood of any radius of a regular language with respect to an additive quasi-distance is regular. As an application we present a simple algorithm that constructs a metric (fault-tolerant) lexical analyzer for any given lexical analyzer and desired radius (fault-tolerance index). 1 Introduction You are frustrated when you type a UNIX command incorrectly and cannot find what the correct spelling is. You may be wondering why the system does not give any suggestions on what command you might want to type. Those questions concern the concepts of distances between words and neighborhoods of languages with respect to a distance and a radius.
