它更多的是从这个矩阵的概念框架，和余弦相似度的概念出现。

The VSM is more of a conceptual framework from which this matrix, and the notion of cosine similarity arise.

这表明，计算余弦相似度，你只需要把那些文件，有一些术语通常与查询。

It follows that, to compute cosine similarity, you only need to consider those documents that have some term in common with the query.
