Java port of Apertium runtime

A "Java port" of Apertium would enable use on

• Windows,
• J2ME/Android phones,
• web pages (applets),
• desktop application,
• Java server applications.

The last 2 is relevant as, for example an OpenOffice.org plugin should be platform independent to be maintainable.

AFAIK we havent seen anyone embedding Apertium in a desktop application. Currently Apertium is usable in a local subdir but installation isnt trivial to an end user, but note that 'embedding' something isnt the same as 'using a locally installed version'.

Having a packaged easy-to-use version of Apertium ready for embedding MT in a larger program would be very cool. Ideally should a self-contained Apertium JAR file, only dependent on JRE and an additional JAR file per language pair.

An "embedding" approach is to use a client stub to an Apertium web service, but there can be reasons why people prefers to have things installed locally (we don't need to repeat them here).

Missing for a complete port of apertium in java is tagger, piping/modes, interchunk/postchunk and format handling.

Af I see it:

• Interchunk/postchunk I could do in very short time, so I could mentor this
• Tagger: The C++ code is there and some has already been ported to Java (lttoolbox-java parts), probably someone could port it relatively easy, if someone understanding tagger would co-mentor that part. I'd say its not necessary to port tagger training, just the core (bigram) tagging during translation.
• Piping/modes isnt too hard.
• Format handling: I'd say that it would be OK just to be able to handle normal text.

Random snippets of information, that someone might find usefull but noone cared to organize yet

<Unhammer> I _think_ those days are OK with me
<jacobEo> Zerocool1989: please co-ordinate with jimregan as he's also working on the code.
<jacobEo> Zerocool1989: I think you first have to try to use a lang par with interchunk and postchunk
* sioraiocht (~tomh@unaffiliated/sioraiocht) has joined #apertium
<Zerocool1989> ok
<Zerocool1989> where can i get the interchunk code
<jacobEo> 1 sec
<jacobEo> esperanto/apertium/apertium/apertium/interchunk.cc
<jacobEo> sorry
<jacobEo> apertium dir in SVN  + /apertium/interchunk.cc
<jacobEo> but Zerocool1989 (and Kanmuri? ) you should compare with  esperanto/apertium/apertium/apertium/transfer.cc 
<jacobEo> and the Java transfer
<jacobEo> is working very differently
<jacobEo> actually, I think the best thing would be not to care about interchunk and postchunk for now, I can probably do them very fast
<jacobEo> better would be to help jimregan on the tagger work.
<jacobEo> and to sort out the modes/piping
<jacobEo> interchunk and postchunk is also only for 3+ - stage transfer. There are language pairs that only have 1 stage.
<jacobEo> so another thing that could be done is to try out an 1-stage lang pair (e.g. nn-nb) and see if you can get the parts running in Java
