Class JaroWinklerDistanceTextSimilarity

java.lang.Object

org.apdplat.word.analysis.TextSimilarity

org.apdplat.word.analysis.JaroDistanceTextSimilarity

org.apdplat.word.analysis.JaroWinklerDistanceTextSimilarity

All Implemented Interfaces:

Similarity, SimilarityRanker

public class JaroWinklerDistanceTextSimilarity
extends JaroDistanceTextSimilarity

文本相似度计算 判定方式：Jaro–Winkler距离（Jaro–Winkler Distance），Jaro的扩展 由William E. Winkler提出，最适合计算短文本如人名的相似度 这里需要注意的是Jaro–Winkler距离也就是相似度分值
