Webb22 okt. 2024 · Cosine similarity is a metric used to determine how similar the documents are irrespective of their size. Mathematically, Cosine similarity measures the cosine of the angle between two vectors projected in a multi-dimensional space. In this context, the two vectors I am talking about are arrays containing the word counts of two documents. http://users.umiacs.umd.edu/~joseph/classes/enee752/Fall09/Solutions1.pdf
