ABOUT:

pos-js is a Javascript port of Mark Watson's FastTag Part of Speech Tagger

which was itself based on Eric Brill's trained rule set and English

lexicon.

pos-js also includes a basic lexer that can be used to extract words and

other tokens from text strings.

pos-js was written by [Percy Wegmann](http://www.percywegmann.com/) and

is [available on Google code](https://code.google.com/p/jspos/). This fork

adds node.js and npm support.

LICENSE:

jspos is licensed under the GNU LGPLv3

INSTALL:

`$ npm install pos`

USAGE:

```javascript

var pos = require('pos');

var words = new pos.Lexer().lex('This is some sample text. This text can contain multiple sentences.');

var tagger = new pos.Tagger();

var taggedWords = tagger.tag(words);

for (i in taggedWords) {

    var taggedWord = taggedWords[i];

    var word = taggedWord[0];

    var tag = taggedWord[1];

    console.log(word + " /" + tag);

}

// extend the lexicon

tagger.extendLexicon({'Obama': ['NNP']});

tagger.tag(['Mr', 'Obama']);

// --> [[ 'Mr', 'NNP' ], [ 'Obama', 'NNP' ]]

```
