Build Status

MyStem

This module contains a wrapper for an excellent morphological analyzer for Russian language Yandex Mystem 3.0 released in June 2014. A morphological analyzer can perform lemmatization of text and derive a set of morphological attributes for each token.

This module start mystem as separate process and commucates with it. This allows to avoid process start overhead.

Example

 
var MyStem = require('mystem3');
 
var myStem = new MyStem();
myStem.start(); // Run mystem in separate process
 
myStem.lemmatize("немцы").then(function(lemma) {
    console.log(lemma);
}).then(function() {
    myStem.stop(); // Or you can write process.exit();
}).catch(console.error);
 

Methods

new MyStem(options)

Return myStem object. Supported options are:

  1. "path" (optional, by default module downloads mystem binary itself) - path to mystem executable. If PATH env variable contains path to the folder with mystem binary then you can write new MyStem({"path": "mystem"})

myStem.start()

Starts mystem as separate process and establishes commucation with it. This gives huge performance boost. As we do not need to start mystem for every word

myStem.stop()

Stops mystem process. Will be automatically stopped on process.exit();

myStem.lemmatize(word)

Returns promise with lemmatized version for passed word

myStem.extractAllGrammemes(word)

Returns promise with array of lemmatized version for passed word and all grammemes
