The only commercial options that I have seen do not have a web presence
(that I know of or can find) and I don't recall the company names (only
peripherally involved).
Here is a web page where a guy does a nice writeup on a few options:

Unfortunately, the license is GPL. Really too bad; now that it is all
Java, it would make a great combo with Lucene.

I believe the code Otis is referring to is here:

This is index-level analysis but could be adapted to work for just a single
document.
The implementation is optimised for speed rather than being a thorough examination of phrase significance.
Cheers

Av, look at Lucene's JIRA and search for Mark Harwood. I believe he once
contributed something that does this in JIRA. If you are interested in a
commercial solution, I can recommend LingPipe.

Subject: Keyphrase Extraction
Hi,
I tried using MoreLikeThis contrib feature to extract "interesting terms" from
a document. This works very well - but only for SINGLE words.
I am looking for a way to extra "keyPHRASES" from a document. Is there an easy
way to achieve this using Lucene index?
Thanks in advance!
Av
