hi andrew
some of us have been working on putting moses onto the OLPC
http://wiki.laptop.org/go/Projects/Automatic_translation_software
which has roughly the same resources as an iphone. We've got it working
for reasonable size models
my advice would be:
1. The moses-cmd shows you how to interact with the moses library.
For normal decoding, it's quite simple. To make it even more simple for
the gui developers, I would create a static library as a replacement for
moses-cmd. Call the static library functions from your gui, rather than
the moses functions directly
2. from what i know of ARM development, there are compiler switches
to enable fast floating point operations. Make sure these are enabled.
3. the moses library assumes lots of memory so caches certain
objects. Look throught this mailing list to see how to turn caching off.
4. Iphone apps can't run in the background so it would be best to
have instant loading. This is not the case with any of our models, which
can take some time to initialize. Speciically the phrase table and
language models. You may have to write new implementations for them.
5. There may be littendian/bigendian issues with the binary phrase
tables & language models. i.e you may not be able to create a binary
phrase table/LM on your desktop and expect it to work on the iphone.
i think its definitely doable, but don't expect just to be able to
compile & go
sounds like a fun project, let us know how it goes.

Hello,
My name is Andrew Haddad. I am a Graduate Research Assistant at Purdue
University. I have been given the task of getting moses working on the
iphone. The moses package, which we have successfully installed and
have running in simulation on the iphone will of course not work due
to some limitations put for by Apple.
I am going to be forced to cross compile the moses static library,
used in moses-cmd, for the arm and i386 architecture. And then rewrite
the functionality of moses-cmd to be used in our application. Do you
know of anyone who has attempted something similar, that might be able
to explain the process?
