Omorfi

OMorFi (Open Morphology of Finnish) is a computational morphology of Finnish written using HFST.

Requirements

You will need HFST installed, you can follow the instructions on the HFST page.

Download

The following commands will download and prepare the build for OMorFi.

$ svn co http://svn.gna.org/svn/omorfi/trunk omorfi
$ cd omorfi/
$ autoreconf -i 
$ ./configure --prefix=/home/fran/local
$ cd src/

Compilation

You need at least 1.5Gb RAM to compile Omorfi, or be willing to let your machine sit around trashing for some hours.

$ make

This will compile everything. If your machine has less than 2Gb RAM you might want to just compile the analyser:

$ make mor-omorfi.hwfst

This could take 10--30 minutes.

Usage

After compiling, you can test it with the hfst-lookup program.

$ echo "kaikki ihmiset syntyvät vapaina ja tasavertaisina arvoltaan ja oikeuksiltaan ." |\
   sed 's/ /\n/g' | hfst-lookup src/mor-omorfi.hwfst

To get the output to something approaching Apertium:

echo "kaikki ihmiset syntyvät vapaina ja tasavertaisina arvoltaan ja oikeuksiltaan." |\
  sed 's/$/¶/g' | sed 's/\W/\n&\n/g' | grep -v '^ $' | hfst-lookup src/mor-omorfi.hwfst |\
  python omorfi-to-apertium.py
