通过将待进行计算的向量放入二维数组中，然后编程实现皮尔森和余弦相似度公式，计算向量之间的相似度。-caculate the similarity of vector

tf-idf程序，朋友写的，很好。对中文句子进行相似度计算，有计算句子权值、排序、两两句子之间的相似度计算。有语料，可以直接运行-tf-idf program, friends wrote, very good. Similarity calculation for Chinese sentences, the sentence weights are calculated, sort, twenty-two similarity between sub-calculation. A corpu

矢量数据绘图系统，比较简单的java程序，如果有雷同，纯属巧合。-Vector data mapping system, relatively simple java program, if there is similarity is purely coincidental.
