Sørensen–Dice coefficient calculator

Calculates the Sørensen–Dice coefficient between two strings:

Turned into a Python module with PyO3 crate (original Rust program here: https://github.com/nebelgrau77/sorensen_dice_coeff).

More than twice as fast than a pure Python function (timed with %timeit in JupyterLab).

How to use:

Copy file:

• sdcoeff.so (Linux) or
• sdcoeff.pyd (Windows)

into the folder where you're running Python.

from sdcoeff import coefficient

# syntax: coefficient(wordA, wordB)

c = coefficient('Philadelphia', 'Philladelphia')

Note: if any of the words is shorter than two characters, i.e. doesn't have a single bigram, function will return 0.

TO DO:

• Currently only compiled for Linux and Windows 10 - compile for MacOS if possible.
