Interface SMStringNGram

All Superinterfaces:

SimilarityMeasure, SMString

All Known Implementing Classes:

SMStringNGramImpl

public interface SMStringNGram
extends SMString

Measures the nGram similarity of two strings. Splits both strings into all possible substrings of length n and computes a distance based on the number of identical sub-strings. The distance is normalized by division through the number of the maximum nGrams of both substrings. The comparison can be case sensitive or insensitive. For further explanation refer to the wiki.
