I wrote a document distance code. It seems working but I couldnt be sure. (I tried for the small strings and it seems working) Also I am not sure that its fast enough for large texts.

I did not use the acos since I dont think I need it.

Edit: People asked what is the document distance I am sharing a link

The frequency is the number of occurrences for each object. Such as for "D1: be or not to be" the frequency will be freq$$(D_1) = {be=2, not=1, or=1, to=2}$$ and $$||D_1|| = \sqrt{2^2 + 1^2 + 1^2 + 2^2}$$

I wrote a script to calculate document distance. It seems working but I couldn't be sure. (I tried for the small strings and it seems working) Also I am not sure that its fast enough for large texts.

Here is the Document Distance formula :

The frequency is the number of occurrences for each object. Such as for "D1: be or not to be" the frequency will be freq$$(D_1) = {be=2, not=1, or=1, to=2}$$ and $$||D_1|| = \sqrt{2^2 + 1^2 + 1^2 + 2^2}$$

I did not use the acos function since I don't think I need it.
