@caijs/spellcheck

This library perform an spell check correction based on a dictionary of frequencies.

Important: this library does not includes any dictionary, as is intended to be used as NLP support building the dictionary based on the utterances used to train.

Installation

In your project folder run:

$ npm install @caijs/spellcheck

Spell Check a word

const SpellCheck = require('@caijs/spellcheck');

const spellCheck = new SpellCheck({
  features: {
    working: 5,
    wording: 2,
    person: 5,
    other: 6
  }
});

const fixed = spellCheck.checkToken('worling', 1);
console.log(fixed); // working

The second parameter is the maximum levenshtein distance between the words. If not provided it assumes 0 so no spell checking is done. It should return "working" and not "wording" because the length is equal but the frequency of the word "working" is greater.

Spell Check an array of words

const SpellCheck = require('./src');

const spellCheck = new SpellCheck({
  features: {
    working: 5,
    wording: 2,
    person: 5,
    other: 6
  }
});

const actual = spellCheck.check(['other', 'peraon', 'is', 'worling', 'on', 'that'], 1);
console.log(actual); // [ 'other', 'person', 'is', 'working', 'on', 'that' ]
