retext-soundex

Retext implementation of the Soundex algorithm.

Installation

npm:

npm install retext-soundex

retext-soundex is also available for bower, component, and duo, and as an AMD, CommonJS, and globals module, uncompressed and compressed.

Usage

var retext = require('retext');
var inspect = require('unist-util-inspect');
var soundex = require('retext-soundex');
 
retext().use(soundex).use(function () {
    return function (cst) {
        console.log(inspect(cst));
    };
}).process('A simple English sentence.');

Yields:

RootNode[1]
└─ ParagraphNode[1]
   └─ SentenceNode[8]
      ├─ WordNode[1] [data={"phonetics":"A000"}]
      │  └─ TextNode: 'A'
      ├─ WhiteSpaceNode: ' '
      ├─ WordNode[1] [data={"phonetics":"S514"}]
      │  └─ TextNode: 'simple'
      ├─ WhiteSpaceNode: ' '
      ├─ WordNode[1] [data={"phonetics":"E524"}]
      │  └─ TextNode: 'English'
      ├─ WhiteSpaceNode: ' '
      ├─ WordNode[1] [data={"phonetics":"S535"}]
      │  └─ TextNode: 'sentence'
      └─ PunctuationNode: '.'

You can also combine it with a stemmer (such as retext-porter-stemmer or retext-lancaster-stemmer).

var retext = require('retext');
var inspect = require('unist-util-inspect');
var soundex = require('retext-soundex');
var stemmer = require('retext-porter-stemmer');
 
retext().use(stemmer).use(soundex).use(function () {
    return function (cst) {
        console.log(inspect(cst));
    };
}).process('A detestable paragraph.');

Yields:

RootNode[1]
└─ ParagraphNode[1]
   └─ SentenceNode[6]
      ├─ WordNode[1] [data={"stem":"a","phonetics":"A000","stemmedPhonetics":"A000"}]
      │  └─ TextNode: 'A'
      ├─ WhiteSpaceNode: ' '
      ├─ WordNode[1] [data={"stem":"detest","phonetics":"D323","stemmedPhonetics":"D323"}]
      │  └─ TextNode: 'detestable'
      ├─ WhiteSpaceNode: ' '
      ├─ WordNode[1] [data={"stem":"paragraph","phonetics":"P626","stemmedPhonetics":"P6261"}]
      │  └─ TextNode: 'paragraph'
      └─ PunctuationNode: '.'

API

None, retext-soundex automatically detects the phonetics of each WordNode (using wooorm/soundex-code), and stores the phonetics in node.data.phonetics. If a stemmer is used, the stemmed phonetics are stored in node.data.stemmedPhonetics.
