German Go Stemmer

An efficient implementation of the German stemming algorithm from snowballstem.org in Golang that does not need any dependency.

Install

go get -u "github.com/antonbaumann/german-go-stemmer"

then import it

import "github.com/antonbaumann/german-go-stemmer"

You can stem queries

stemmed := stemmer.Stem("wie wird das wetter morgen in münchen")
// "wett morg munch"

or just words one by one

stemmed := stemmer.StemWord("kategorischen")
// "kategor"

or multiple keywords

stemmed := stemmer.StemWords([]string{"kategorisch", "kategorische", "kategorischen"})
// []string {"kategor", "kategor", "kategor"}
