stemmer

This package implements a stemming algorithm in Dart. Currently, it supports PorterStemmer and SnowballStemmer. It is a port of the exceptional Python NLTK library.

About

This package allows for stemming of words. This process reduces a word to their base form. In many cases, the word will not even be recognisable. Where, for example, running would be stemmed to run, which is still a valid word, yet agreed would be stemmed to agre.

Example

PorterStemmer

import 'package:stemmer/stemmer.dart';

PorterStemmer stemmer = PorterStemmer();
stemmer.stem('running'); // outputs: run

SnowballStemmer

import 'package:stemmer/stemmer.dart';

SnowballStemmer stemmer = SnowballStemmer();
stemmer.stem('running'); // outputs: run

Case sentitive stemming

The default behaviour is to always return lowercase stemmed words. However, if you wish you can keep the original casing.

import 'package:stemmer/stemmer.dart';

SnowballStemmer stemmer = PorterStemmer();
stemmer.stem('Running'); // outputs: Run
