With the Calais Auto Tagger plugin, you’ll never have to think of tags for your posts again. The plugin uses the Open Calais API to perform semantic analysis of your post text and suggest tags for you. The plugin adds a new “Get Tag Suggestions” button to your post interface which retrieves the suggestions. Adding the suggested tags takes just a click.
The Calais Auto Tagger requires you have an Open Calais API key. Getting a key is easy as filling out two forms — it’s an instant, automated process. First, go to the Open Calais site and use the “Request API Key” link at the top of the page to create an account. Enter your API key on the Calais Configuration page under the settings menu.
Calais Auto Tagger is compatible with WordPress 2.7+. It is free for personal and commercial use.
Release Date: 1/6/2012
Download: WP Calais Auto Tagger at the WordPress Codex
This plugin relies on the Open Calais Tags PHP class, which requires PHP 5 web hosting with PHP’s cURL extension enabled (the majority of web hosts).
To install, unzip the archive and upload the files to wp-content/plugins/calais-auto-tagger. Then activate the plugin from the plugins tab of your WordPress administration area. You’ll now have a “Calais API Key” link on your settings menu where you can enter your API key.
What’s new in the latest version?
Rewritten to use jQuery, updated the style a bit to better match the current WordPress admin area, and updated the OpenCalais class bundled with the plugin. The new version of my OpenCalais class suggests more tags using the “Social Tags” API in addition to the entity API.
