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

Requirements[edit]

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

Download[edit]

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

$ git clone https://github.com/flammie/omorfi
$ cd omorfi/
$ ./autogen.sh
$ ./configure

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

Compilation[edit]

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.

To prepare source code for new apertium language pair, use src/scripts/omor2apertium.sh... or just copy one from an existing pair, such as apertium-fin-eng.

Usage[edit]

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