A C implementation of Nilsimsa for Python.

Project description

# cNilsimsa

A C implementation of Nilsimsa for Python.

`shell $ pip install cnilsimsa `

We are building this module one piece at a time. So far, that means only compare_hexdigests because needing a faster way to do that was the primary motivation to start this project.

`python from cnilsimsa import compare_hexdigests `

It works exactly like the method of the same name from pynilsimsa but is more than an order of magnitude faster, so if you need to do lots of deduplication over a large corpus of documents via nilsimsa hex digests from Python, this should be helpful.

Building out the rest of of the methods for representing and cooking LSHs to provide a full drop-in replacement for pynilsimsa is the longer term goal.

`python import cnilsimsa as nilsimsa `

Thanks to the authors of the Ruby/C implementation from which our our fillpopcount() function is taken.

Thanks to the Perl/C implementation that inspired both predecessors.
