POS

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. It also includes a basic lexer that can be used to extract words and other tokens from text strings. Originally this was written by Percy Wegmann and is available on Google code.

This fork adds TypeScript support to a fork made by Darius Kazemi which added Node.JS and npm support.

Installation

npm install @devil7softwares/pos

(or)

yarn add @devil7softwares/pos

Usage

import { Lexer, Tagger, TagType } from '@devil7softwares/pos';

const lexer = new Lexer();
const tagger = new Tagger();

const words = lexer.lex('This is some sample text. This text can contain multiple sentences.');
const taggedWords = tagger.tag(words);

for (const [word, tag] of taggedWords) {
    console.log(word + ' /' + tag);
}
