stemmer

Package stemmer is a set of Snowball language stemmers, implemented as transform.Transformer (see golang.org/x/text/). Implementing transform.Transformer allows use with the x/text ecosystem.

(Stemming is the process of trimming words down to their roots, usually for searching purposes.)

My narrower motivation is to offer stemming in this Unicode text segmenter. To use a stemmer in that package, you will call the Transform method on a Segmenter or Scanner, along the lines of:

import "github.com/clipperhouse/stemmer"

text := []byte("I've got my skis and I am heading to the mountains.")
segmenter := words.NewSegmenter(text)
segmenter.Transform(stemmer.English)

// do stuff with segmenter

This stemmer package is a thin layer over this Snowball package, thanks to Bleve.
