Is there a method to calculate text similarity?

I wasn’t expecting anything complex, but it was effective enough to validate duplicate content that was similar from one column to another. The content of this article is about three paragraphs or more.


Thanks, Darren,
Sorry, I have two text fields that the user must fill in. They are not allowed to fill with similar content above 40%. What method can I use to validate it?

So some sort like plagiarism check?

Yes, something like that.

A Google search for “text similarity API” turns up several promising results. I’d imagine it wouldn’t be too difficult to implement something with the Fetch JSON plugin.


Excellent, I’ll give it a try.
thank you very much.
