This stemming module for Node.js provides stemming capability for a variety of languages using Dr. M.F. Porter's Snowball API. That allow you to get from a word a reduced, inflected (or sometimes derived) word from the original word stem, base or root.
A stemmer for English, for example, should identify the string "cats" (and possibly "catlike", "catty" etc.) as based on the root "cat", and "stemmer", "stemming", "stemmed" as based on "stem". A stemming algorithm reduces the words "fishing", "fished", and "fisher" to the root word, "fish". On the other hand, "argue", "argued", "argues", "arguing", and "argus" reduce to the stem "argu" (illustrating the case where the stem is not itself a word or root) but "argument" and "arguments" reduce to the stem "argument".
This library is using bindings to the libstemmer C library. It's support
More about Stemming:
npm install node-snowball
var snowball = require('node-snowball'); // Using String snowball.stemword('consignment'); // 'consign' // Using String and a specific language algorithm snowball.stemword('consignment', 'english'); // 'consign' snowball.stemword('continuation', 'french'); // 'continu' // Or using Array of string snowball.stemword(['consignment', 'conspiring'], 'english'); // ['consign', 'conspiri'] snowball.stemword(['continuation', 'contrainte'], 'french'); // ['continu', 'contrain']
snowball.stemword( word || words, // The word or group of words that you need the stemming from language, // The language (optional, default is "english") encoding // The text encoding (optional, default is "UTF-8") );
