java.lang.Object

org.apdplat.word.analysis.TextSimilarity

org.apdplat.word.analysis.EuclideanDistanceTextSimilarity

All Implemented Interfaces:

Similarity, SimilarityRanker

public class EuclideanDistanceTextSimilarity
extends TextSimilarity

文本相似度计算 判定方式：欧几里得距离（Euclidean Distance），通过计算两点间的距离来评估他们的相似度 欧几里得距离原理： 设A(x1, y1)，B(x2, y2)是平面上任意两点 两点间的距离dist(A,B)=sqrt((x1-x2)^2+(y1-y2)^2)
