New Posting Features - Automatic Thread Tagger for vB4.x

Automatic Thread Tagger
This is the vB4 conversation of the original by Phalynx (with permission)

Description
When a user submits a new thread this modification will automatically take keywords from the thread title and use these as tags. You can use Automatic Thread Tagger to propose the user AJAX tags for his new thread, or it assigns new tags after saving the new thread. It can add the translated thread prefix to the tags.
Additionally, you can tag existing threads via maintenance and also scheduled tasks.

This modification is a successor to the terminated Automatic Thread Tagger by MrEyes:
https://vborg.vbsupport.ru/showthread.php?t=179927

As an example, if a user submits a thread with a title of:
"Fish Food for Cats!"

The thread will be automatically tagged with:

- Fish
- Food
- Cats

If the user also submits an actual tag of "Fish" this will not be duplicated. Any rules you have setup for tagging will be respected.
If you choose to do so this product will also automatically tag threads created by incoming RSS feeds.

Demo
I cannot show you the process of creation, but here is a list of tags generated by Auto Thread Tagger:
http://www.insideearth.net/tags.php?langid=5
http://www.insidesupcom.de/tags.php?langid=1

Automatic Tagging of existing threads
You can tag existing threads via maintenance or scheduled task/cron. They will be created with a special flag so they can be easily identified and deleted. Manual assigned tags are not touched. Maintenance is also working if Automatic Tagging is disabled via settings. Great if you want to test some settings. Automatic Tagging will take the date of the thread creation and also the userid of the creator. This process can be automated by running a scheduled job once a night.

Please keep in mind that tags that were proposed via AJAX are not tagged as auto tagged and therefore cannot be identified as such (and therefore not deleted automatically). If you want to retain the auto tagged flag you should disable AJAX and enable the tagging after the thread has been saved. As an alternative way you can also disable this and let new threads be tagged in the night from the scheduled job.

Installation
1. Upload all files from "upload" to your server, take care of the directory structure
2. Import "product-auto_thread_tagger110.xml" as a product, overwrite if it's already installed
3. Check settings
4. Run maintenance / Auto Tag Threads to tag existing threads (needed if you want to use the cron)

After install, and by default the modification is disabled, this will allow you to play around with configuration before switching it on.

Why thread title and not thread text?
Parsing the thread text for tags is an extremely unlikely addition as this would require some fairly heavy processing to ensure quality of tags.

What are Stopwords?
Stopwords is the name given to words which are filtered out prior to processing of tags.

same mistakes, I tried changing ozzy but has no effect

the plugin that generates the error is this
Automatic Thread Tagger threaddata_postsave

[Phaedrus]

split/explode isn't enough to get rid of all the errors. This causes my forum to freeze on editing a post.

[Phaedrus]

Uninstalled but tagged just in case it works later. Even with the updates listed previously in this thread this caused errors on my forum. Tried the other auto tagger, but it too caused errors. 4.2.2 PL1

Here's to hoping to update this later.

[krimznheidiz]

Is this working for 4.2.2?

[pablodip]

Thanks you ozzy47, is mod run good 4.2.2

EDIT:

Hi, I've had to disable as it brought me problems in threads, when a user edits and gives branded store stays .. and have to refresh the page to see the results

[jim@ars]

Is there any way, out of the box, to prevent tagging in a particular forum or do I need to put on my PHP hat?

[mdawg]

Does this work with vb 4.2.5 running PhP 7?
