My users provide some description ( TEXT field) and I would like to  
generate tags automatically from them?

are there any plugins available?. Any directions would be appreciated.

cheers

Looks like acts\_as\_taggable\_on is what you need. The example included  
on that page should make it pretty easy to do.

Thanks Kyle, unfortunately there is no provision wherein it generates  
tags automatically ( I still have to assign it explicitly - which I  
don’t want to)

You’re trying to pick out keywords out of the description to use as  
tags? You could use a language parser to pick out sentence components

- Subject, Direct Object - and use those as tags.
