Revision as of 07:13, 20 April 2010

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/
$ ./autogen.sh
$ ./configure --prefix=${HOME}/local

In case autogen.sh does not work, do report a bug (autoreconf -i should work just as well in the meantime).

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:

$ cd src
$ make mor-omorfi.hfst

This could take 10--30 minutes.

Key

Feature Notes
KTN Inflection class as it is in official dictionary (the first 49 or so are for nouns, the 52 through 72 for verbs)
KAV Code (K) for consonant gradation (astevaihtelu (AV)). This is a letter from A to K or so.
PCP VA participle is the VA participle, i.e., the present participle

cf. [Omorfi's documentation on inflection for up-to-date table]

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.hfst

To get the output to something approaching Apertium use mor-omorfi.apertium.hfst instead

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.apertium.hfst
