ABOUT:

jspos 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.
jspos also includes a basic lexer that can be used to extract words and other
tokens from text strings.

LICENSE:

jspos is licensed under the GNU LGPLv3

FILES:

lexicon.js_ - Javascript version of Eric Brill's English lexicon
lexer.js - Lexer to break a sentence into taggable tokens (e.g. words)
POSTagger.js - the Part of Speech tagger

You'll typically need to include all 3 files.

USAGE:

var words = new Lexer().lex("This is some sample text. This text can contain multiple sentences.");
var taggedWords = new POSTagger().tag(words);
for (i in taggedWords) {
    var taggedWord = taggedWords[i];
    var word = taggedWord[0];
    var tag = taggedWord[1];
}

ACKNOWLEDGEMENTS:

Thanks to Mark Watson for writing FastTag, which served as the basis for jspos.

The orignal of this code is avallable http://code.google.com/p/jspos/

Kieren Diment <zarquon@cpan.org> added the demo.html and main.js files.

The next step is to add noun phrase extraction routines and other utility functions (see the Perl Module Lingua::EN::Tagger: http://search.cpan.org/perldoc?Lingua::EN::Tagger ).
