余弦相似度Cosine Similarity相关计算公式 余弦相似度,又称为余弦相似性,是通过测量两个向量的夹角的余弦值来度量它们之间的相似性。 两个方向完全相同的向量的余弦相似度为1,而两个彼此相对的向量的相似度为-1。 注意,它们的大小并不重要,因为这是方向的度量。

By measuring the cosine of the angle, we obtain a value between -1 and 1, representing the degree of similarity. A value close to 1 indicates strong similarity, while a value close to -1 suggests dissimilarity. Mathematics Behind Cosine Similarity ...
cosine similarity is given by"dot product / (document + query magnitudes) = cosine". term vector theory makes no provision for document normalization:"there's no concept of normalizing the length of the documents". What a bunch of non sense. All these claims by this alleged "post grad teac...
