Does SF have an API similar to RAKE algorithm that extracts keywords from texts?

I wonder if there is an API in Salesforce Apex that can extract keywords from texts.
If not, does Apex allow a programmer to import any library like Java does?

Hi Felix, 
Out of the box, I don't think so. Salesforce won't allow you to import Java libraries directly.  

But still, you can try . Follow this steps 
  • Use Heroku connect ( So you can load your data out from Salesforce to Postgres database )
  • Use any external ( Like Java API ) to update the data into Heroku Connect 
  • Heroku Connect is having capability to sync data back to Salesforce 

Thanks ,
Raj
