This module contains a wrapper for an excellent morphological analyzer for Russian language Yandex Mystem 3.1 (3.0 for 32bit architectures). 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.
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);Return myStem object. Supported options are:
- "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"})
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
Stops mystem process. Will be automatically stopped on process.exit();
Returns promise with lemmatized version for passed word
Returns promise with array of lemmatized version for passed word and all grammemes
