Class CosineDistance
java.lang.Object
org.apache.commons.text.similarity.CosineDistance
- All Implemented Interfaces:
EditDistance<Double>
,SimilarityScore<Double>
public class CosineDistance extends Object implements EditDistance<Double>
Measures the cosine distance between two character sequences.
It utilizes the CosineSimilarity
to compute the distance. Character sequences
are converted into vectors through a simple tokenizer that works with a regular expression
to split words in a sentence.
