Contents
* [`unified().use(retextPos)`](#unifieduseretextpos)What is this?
This package is a unified (retext) plugin to add part of speech tags to words. It usesdariusk/pos-jsposjs and adds node.data.partOfSpeech on
Wordnlcst-word nodes.
It works by checking each sentence, so its smarter that just passing one word
through.When should I use this?
You can either use this plugin if another plugin, or your own plugin, needs POS tags!Install
