Auto create tags with RSS Multi import

Dear experts,

I am using the plugin “RSS Multi Import” to grab content from an RSS-feed and import it into my database. Since this is an automated proces, I do not physically click on any button before a post is published. And because this is automated, I never get a chance to add tags to the post before it is published. If I want to add tags to my posts, I need to edit each single post manually and create the tags.

There are plugins that can automatically write tags, based on title or content. However, these plugins all bind to the “edit” button. With over a 1000 posts each day, I can not manually click [EDIT] for every post and create tags that way.

I would like my posts to automatically have each word of the content as a seperate tag on auto-publish. Through a custom PHP-script that I wrote, I can remove tags based on an array of “bad tags”.

This script can be run trough CRON so that bad tags get removed frequently. The content of my posts is limited to the first two sentenses, so the amount of tags per post is limited as well.

I checked wp_post_set_terms, but that use existing posts based on post_id. Is there any other way that I can have RSS Multi Import create tags directly on publish?

Any help is much appreciated!
