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.
Thanks to Toby Rahilly for compressing the lexicon.
