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 and is available on Google code. This fork adds node.js and npm support.
LICENSE:
jspos is licensed under the GNU LGPLv3
INSTALL:
$ npm install pos
USAGE:
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' ]]
