Hi, i’ve some long texts. do you know if it’s possible to check if a  
given text is already on the web? maybe with a % of similarity. For  
example a text which is \>75% similar with another on the web isn’t  
unique.  
Any advice?

This is not a simple problem, but there are some companies trying to  
solve it:
