Cosine Similarity

[subhabangalore]

Dear Group,

I am looking for some example of implementing Cosine similarity in python. I searched for hours but could not help much. NLTK seems to have a module but did not find examples.

If anyone of the learned members may kindly help out.

Regards,
Subhabrata.

Should be easy with numpy:
import numpy as np

def cos(v1, v2):
return np.dot(v1, v2) / (np.sqrt(np.dot(v1, v1)) * np.sqrt(np.dot(v2, v2)))


HTH,
