Description

A native Go clean room implementation of the Porter Stemming Algorithm.

This algorithm is of interest to people doing Machine Learning or Natural Language Processing (NLP).

This is NOT a port. This is a native Go implementation from the human-readable description of the algorithm.

I’ve tried to make it (more) efficient by NOT internally using string’s, but instead internally using []rune’s and using the same (array) buffer used by the []rune slice (and sub-slices) at all steps of the algorithm.
