Luis,
In addition to the multi-engine MT by Gabriel, there have been many
avenues to hybridization involving Apertium, and Felipe Sánchez-Martínez
has been part of most of them (check his webpage
http://www.dlsi.ua.es/~fsanchez/). I'll answer now, and he can complete
my answer later:
1. Felipe, Juan Antonio Pérez-Ortiz and I used nondeterministic
output followed by scoring with a statistical target-language
model to train the part-of-speech tagger of Apertium. However, he
managed to transfer the scores to the part-of-speech tagger so
that it would only deliver one analysis, with similar results.
The whole thing is implemented and is part of Apertium: Felipe
will tell you which packages. The main paper is:

2. Another thing that Felipe Sánchez-Martínez did was to mix
translation units from a corpus with Apertium output. We published
a paper on this;
* http://www.dlsi.ua.es/~fsanchez/pub/pdf/sanchez-martinez09d.pdf
3. Finally, Felipe's student Víctor Sánchez Cartagena has been
working hard in hybridization, adding Apertium-generated
translation units to a statistical MT system (the resulting
system, Alacant, was one of the best systems in the WMT 2011
contest for Spanish--English, see
http://www.mt-archive.info/WMT-2011-Callison-Burch.pdf):

Hope this has helped!
Good luck

Hello,
My name is Luis and I'm very interested in this project and what it
can do, it's really amazing!
I wanted to know if there have been attempts to combine the rule-based
approach of apertium with some statistical processing. For example,
has anybody tried to get a non-deterministic output from apertium
rules, and then use another method to choose between the possible
outcomes? I really would like to try this out. I've been googling to
know if someone took that approach, but I haven't been able to find
anything on the subject.
Thanks,
Luis
