natural language processing, and information retrieval. After reading this article, you will know precisely what cosine similarity is, how to run it with Python using the scikit-learn library (also known as sklearn), and when to use it. You’ll also learn how cosine similarity is ...
Python’snumpylibrary provides powerful array operations, making it suitable for computing cosine similarity. To calculate cosine similarity using NumPy, we can leverage thenp.dot()andnp.linalg.norm()functions. Thenumpy.dot()functiontakes two input arrays or matrices and computes their dot product....
To do so, we also consider its relationship to cosine similarity. Cosine distance formula Cosine distance measures the dissimilarity between two vectors by calculating the cosine of the angle between them. It can be defined as one minus cosine similarity, as we see in the formula below: In a...

Cosine similarity is a metric used to measure how similar the documents are irrespective of their size. It is the cosine of the angle between two vectors.
Now that we have a Vector Space Model of documents (like on the image below) modeled as vectors (with TF-IDF counts) and also have a formula to calculate the similarity between different documents in this space, let’s see now how we do it in practice using scikit-learn (sklearn...
