Detecting Elements of Sentence In Ruby

Question

My aim is detecting simple elements in any sentence such as verb, noun or adjective. Is there any gem in Ruby for achieving that? For example:

They elected him president yesterday.

Output:

["subject","verb", "object", "predicative", adverbial"]

These are the only natural language processing options for Ruby that I know of.

Interestingly, they are all by the same person.

EDIT Here is one more option that I found. It's a tutorial on n-gram analysis.

The Ruby wrappers are from the same person, but the libraries behind are not! – Blacksad Nov 14 '13 at 22:19
I tried both Open NLP and Treat and Treat literally beats Open NLP in nameTagger. It's very extensive. – Tugkan Dec 18 '13 at 11:48

I've used engtagger with good success in the past. It's ported from a Perl program called Lingua::EN::Tagger. It takes a bit of work to get it to do what you want, but I think it's the best tool available for this application (at least at the moment).

does it give the elements as array or just with the tags? – Tugkan Nov 14 '13 at 15:06

depends - you can get them as a hash with the frequency as value, but if you fiddle just a bit you could very easily make the output anything you want – dax Nov 14 '13 at 15:12
Part-of-Speech tagging is good in engtagger but it's noun phrase method isn't really dependable. – Charlie Egan Nov 08 '14 at 16:00
