'''Matxin''' is a free software machine translation engine related to [[Apertium]]. It allows for deeper transfer than can be found in Apertium. The linguistic data available under a free licence is a fraction of the data that is used in the papers and descriptions of the subject, so naturally the translations from the pair will be less good than you can find results in the papers.

This page describes how to install the system, see [[Matxin#Documentation]] below for how to create or maintain language pairs.

Questions and comments about Matxin can be sent to their mailing list [https://lists.sourceforge.net/lists/listinfo/matxin-devel matxin-devel], or to the [https://lists.sourceforge.net/lists/listinfo/apertium-stuff apertium-stuff] list.

==Prerequisites==

* BerkleyDB — sudo apt-get install libdb4.6++-dev
* libpcre3 — sudo apt-get install libpcre3-dev

Install the following libraries in <prefix>,

* libcfg+ &mdash; http://platon.sk/upload/_projects/00003/libcfg+-0.6.2.tar.gz
* libomlet &mdash; https://lafarga.cpl.upc.edu/frs/download.php/130/libomlet-0.97.tar.gz
* libfries &mdash; https://lafarga.cpl.upc.edu/frs/download.php/129/libfries-0.95.tar.gz
* FreeLing (from SVN) &mdash; (<code>svn co http://devel.cpl.upc.edu/freeling/svn/latest/freeling</code>)
:If you're installing into a prefix, you'll need to set two environment variables: CPPFLAGS=-I<prefix>/include LDFLAGS=-L<prefix>/lib ./configure --prefix=<prefix>
* [[lttoolbox]] (from SVN) &mdash; (<code>svn co https://apertium.svn.sourceforge.net/svnroot/apertium/trunk/lttoolbox</code>)

==Building==

;Checkout

<pre>
$ svn co http://matxin.svn.sourceforge.net/svnroot/matxin
</pre>


==Installation==
Then do the usual:


<pre>
<pre>
$ git clone https://github.com/matxin/matxin.git
$ ./configure --prefix=<prefix>
$ cd matxin/
$ ./autogen.sh
$ make
$ make
</pre>

After you've got it built, do:

<pre>
$ su
# export LD_LIBRARY_PATH=/usr/local/lib
# export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
# make install
# make install
</pre>
</pre>


==Executing==
==Language pairs==


* [[matxin-spa-eus]]
The default for <code>MATXIN_DIR</code>, if you have not specified a prefix is <code>/usr/local/bin</code>, if you have not specified a prefix, then you should <code>cd /usr/local/bin</code> to make the tests.
* [[matxin-eng-eus]]

Bundled with Matxin there's a script called <code>Matxin_translator</code> which calls all the necessary modules and interconnects them using UNIX pipes. This is the recommended way of running Matxin for getting translations.

<pre>
$ ./Matxin_translator -f $MATXIN_DIR/share/config/es-eu.cfg
</pre>

For advanced uses, you can run each part of the pipe separately and save the output to temporary files for feeding the next modules.

<pre>
$ export MATXIN_DIR=<prefix>
$ echo "Esto es una prueba" | \
./Analyzer -f $MATXIN_DIR/share/matxin/config/es-eu.cfg | \
./LT -f $MATXIN_DIR/share/matxin/config/es-eu.cfg | \
./ST_inter --inter 1 -f $MATXIN_DIR/share/matxin/config/es-eu.cfg | \
./ST_prep -f $MATXIN_DIR/share/matxin/config/es-eu.cfg | \
./ST_inter --inter 2 -f $MATXIN_DIR/share/matxin/config/es-eu.cfg | \
./ST_verb -f $MATXIN_DIR/share/matxin/config/es-eu.cfg | \
./ST_inter --inter 3 -f $MATXIN_DIR/share/matxin/config/es-eu.cfg | \
./SG_inter -f $MATXIN_DIR/share/matxin/config/es-eu.cfg | \
./SG_intra -f $MATXIN_DIR/share/matxin/config/es-eu.cfg | \
./MG -f $MATXIN_DIR/share/matxin/config/es-eu.cfg | \
./reFormat

Then change the header files in <code>src/Analyzer.C</code> to:

<pre>
//#include "freeling.h"

#include "util.h"
#include "tokenizer.h"
#include "splitter.h"
#include "maco.h"
#include "nec.h"
#include "senses.h"

Upon finding yourself battling the following compile problem,

<pre>

Make the following changes in the file <code>src/Analyzer.C</code>:

<pre>
if (cfg.TAGGER_which == HMM)
- tagger = new hmm_tagger(cfg.Lang, cfg.TAGGER_HMMFile, cfg.TAGGER_Retokenize, cfg.TAGGER_ForceSelect);
+ tagger = new hmm_tagger(string(cfg.Lang), string(cfg.TAGGER_HMMFile), false);
else if (cfg.TAGGER_which == RELAX)
- tagger = new relax_tagger(cfg.TAGGER_RelaxFile, cfg.TAGGER_RelaxMaxIter,
+ tagger = new relax_tagger(string(cfg.TAGGER_RelaxFile), cfg.TAGGER_RelaxMaxIter,
cfg.TAGGER_RelaxScaleFactor, cfg.TAGGER_RelaxEpsilon,
- cfg.TAGGER_Retokenize, cfg.TAGGER_ForceSelect);
+ false);
if (cfg.NEC_NEClassification)
neclass = new nec("NP", cfg.NEC_FilePrefix);
if (cfg.SENSE_SenseAnnotation!=NONE)
- sens = new senses(cfg.SENSE_SenseFile, cfg.SENSE_DuplicateAnalysis);
+ sens = new senses(string(cfg.SENSE_SenseFile)); //, cfg.SENSE_DuplicateAnalysis);
</pre>

Then probably there will be issues with actually running Matxin.

If you get the error:

<pre>
config.h:33:29: error: freeling/traces.h: No such file or directory
</pre>

Then change the header files in <code>src/config.h</code> to:

<pre>
//#include "freeling/traces.h"
#include "traces.h"
</pre>

If you get this error:

<pre>
$ echo "Esto es una prueba" | ./Analyzer -f /home/fran/local/share/matxin/config/es-eu.cfg
Constraint Grammar '/home/fran/local//share/matxin/freeling/es/constr_gram.dat'. Line 2. Syntax error: Unexpected 'SETS' found.
Constraint Grammar '/home/fran/local//share/matxin/freeling/es/constr_gram.dat'. Line 7. Syntax error: Unexpected 'DetFem' found.
Constraint Grammar '/home/fran/local//share/matxin/freeling/es/constr_gram.dat'. Line 10. Syntax error: Unexpected 'VerbPron' found.
</pre>

You can change the tagger from the RelaxCG to HMM, edit the file <code><prefix>/share/matxin/config/es-eu.cfg</code>, and change:

<pre>
#### Tagger options
#Tagger=relax
Tagger=hmm
</pre>

Then there might be a problem in the dependency grammar:

<pre>
$ echo "Esto es una prueba" | ./Analyzer -f /home/fran/local/share/matxin/config/es-eu.cfg
DEPENDENCIES: Error reading dependencies from '/home/fran/local//share/matxin/freeling/es/dep/dependences.dat'. Unregistered function d:sn.tonto
</pre>

The easiest thing to do here is to just remove references to the stuff it complains about:

<pre>
cat <prefix>/share/matxin/freeling/es/dep/dependences.dat | grep -v d:grup-sp.lemma > newdep
cat newdep | grep -v d\.class > newdep2
cat newdep2 | grep -v d:sn.tonto > <prefix>/share/matxin/freeling/es/dep/dependences.dat
</pre>
===Error in db===

If you get:
*SEMDB: Error 13 while opening database /usr/local/share/matxin/freeling/es/dep/../senses16.db

rebuild senses16.deb from source:
*cat senses16.src | indexdict senses16.db
* (remove senses16.db before rebuild)

Matxin is a free software machine translation engine related to Apertium. It allows for deeper transfer than can be found in Apertium.

This page describes how to install the system, see Matxin#Documentation below for how to create or maintain language pairs.

Installation[edit]

$ git clone https://github.com/matxin/matxin.git
$ cd matxin/
$ ./autogen.sh 
$ make
# make install

Language pairs[edit]

Troubleshooting[edit]

Can't find AP_MKINCLUDE



set your ACLOCAL_PATH to include the path to matxin.m4

Documentation[edit]

Contact[edit]

Questions and comments about Matxin can be sent to their mailing list matxin-devel, or to the apertium-stuff list.
