WP Calais Auto Tagger

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.

Calais Auto Tagger

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 “Register” link at the top of the page to create an account. Then, request an API key by filling out this form. Enter your API key on the Calais Configuration tab of your plugins page.

Calais Auto Tagger is compatible with WordPress 2.7+. It is free for personal and commercial use.

Current Version

Version: 1.3.1
Release Date: 11/03/2009
Download: WP Calais Auto Tagger at the WordPress Codex

Notes

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).

Installation

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.

    Hi Dan, this is a great development. As a suggestion, I think there’d be a huge demand for a similar tool that would be “open” to non-wordpress usage. I’m thinking of a website where I could input my blog text (or any text for that matter) and receive top tags in return. That would greatly expand your reach as many people (like me) don’t use wordpress. Really look forward to your next developments!

    For some reason I can’t activate the plug-in on my blog using WP 2.5
    I’m getting this error:

    Joe, the plugin requires PHP 5. Greg, have you looked at the linked Open Calais Tags class? You can use it to add automatic tagging to any app you want.

    Dan wrote —

    Perhaps that feature requires 5.1 after all. I’ve tested it against three hosts, but all of them had at least PHP 5.1.

    Please try downloading it again and using the updated opencalais.php. I removed the line you had an error on and hard-coded the string where it was used.

    that must be it. got the same error message after downloading the new version. don’t know how I get GoDaddy to upgrade to 5.1

    You can’t still be getting an unexpected T_CONST error on line 17 since that line, and the const, were removed. Are you sure you replaced your files with the new opencalais.php? If you’re not in a rush and want some help with this, you can e-mail me at dan@dangrossman.info.

    Actually, he’s right. I get the same message, blah blah T_CONST blah Line 17 etc…

    Double checked that there was no “T_CONST” in the file, there wasn’t. Not sure what’s up there.

    I’m on powweb, also PHP 5.0 IIRC

    Dan,

    One question: When I get my Open Calais API key and then try to input it and click on Submit, nothing happens. I am using WordPress 2.5. Have tried doing this in Firefox 2.0 and IE 6 and nothing works.

  10. April 11th, 2008

    Dan wrote —

    Dirkus, Joe’s problem was that he was actually running PHP 4. If you’re getting an error on that line you probably are too. Create an empty PHP page with just a call to phpinfo(), run it in your browser, and you’ll see the version.

  11. April 11th, 2008

    Steve Oberg wrote —

    Dan, never mind. Dumb me, the API key WAS registered ok, after all. Everything’s work.

    Oh, also just to suggest that you update the link to the archive tagger above. Currently the link is http://www.dangrossman.ino/wp-calais-archive-tagger and it should be, I think, http://www.dangrossman.info/wp-calais-archive-tagger.

    Can’t wait to try both of these nifty tools. Thank you for making them available.

    Ah, apparently so. I thought they had moved to PHP5, but I guess I was mistaken. Thanks.

    Connor, you need PHP 5 to use this plugin. You only have PHP 4. Ask your host if you can enable PHP 5 for your account or if they will upgrade.

    Great plugin!

    Doe sit only work when the visual editor is activated? Usually when the HTML editor is activated instead, when I click “Get Tags,” nothing happens, even for several minutes.

    Unfortunately it seems when I do use the visual editor, it usually says that no tags were found.

    Is there an option to set these plugins to run completely ‘hands free’ ?

    Dan,
    Thanks for the plugin! I think I may have stumbled across a reason, and solution for the “IT’S NOT WORKING” posts.
    I was running through old posts without any difficulty and then ran into one where it wouldn’t work. Realized the Post window on the Write screen was set on HTML tab, not the Visual tab. I changed the Post to the Visual tab, then rehit auto tag and it worked just fine. I suspect, although did not re-check, that this was why I had been unable to get the archive tagger to work. May want to make this a note on the WP plugin download page.
    I hope this helps as you have a great, time saving plugin.

    It looks nice, but it’s too bad it isn’t backwards compatible with pHp 4. That is what my webhosting service is using right now. Is there a workaround for the parse error on line 132 mentioned by Veetrag above?

    There is not and will not be a backport of the Calais PHP class to a dead language. Tell your host that PHP 5 is more than 4 years old and you need an upgrade out of the stone age.

    Hi There

    What we really need is an automatic tagging plugin. Not a semi automatic tagging plugin. We all have so many blogs running on their own and grabbing good relevant content from other feeds etc. We need a plugin that will automatically tag the posts in the database without having to login and click somewhere.

    Man what I would do for such a plugin. Can’t find anything like it.

    Thanks,
    Albert

    To be clear, this plugin works fine with WP 2.7.1. If it’s not for you, you don’t have PHP 5 or cURL, which are listed as requirements.

    That’s because you don’t have PHP 5 unclenoob, not because you’re on 2.8. PHP 5 is a requirement.

    Dan, if you get a moment, could you let me know where I’m going wrong?

    I’ve used both this and the archive tagger for a long time. (OK, to be honest, had them /installed/ for a long time, I’ve been v.bad at tagging posts at all the last nine months or so. I originally went through all my old posts, auto-tagged them, then cleaned up some of the tags.)

    Anyway, I believe I’m on PHP5 and have cURL enabled; I have Wordpress 2.8 installed, and the latest version of both plugins. I write in English, and believe my Calais API key to be correct.
    However, whether I run the archive auto-tagger, or click the get tags button whilst writing/editing a new/old post, no tags are returned. No error messages either. I’ve tried the get tags button on a few different, medium to long posts, in case the subject matter wasn’t providing enough material for tagging.
    With the auto tagger, no response at all, and with the archive auto tagger, it displays Tagged post #6: Tagged post #7: Tagged post #6: (I’ve obviously removed line breaks, and the tagged post #6: carries on for another 8 screens, before I pressed escape.)

    Could you let me know if I’ve goofed up somewhere here, or if there is some sort of debug mode I can use – if the output would be of any use to you.

    Paul, if this is the site you entered as your website when commenting, it doesn’t look like there’s much to tag. Calais picks out people, places, companies, and other big topics. None of those kinds of things appear in ingredient lists.
