This is the README file for the new version of TRmorph (updated 2013-07)
TRmorph is a open source/free morphological analyzer for Turkish. The current version is a complete rewrite of the (earlier) SFST version of TRmorph using xfst/lexc. This version is in active development, which may cause some problem and incompatibilities between updates. However, the status is a lot better than the older SFST version, and you are recommended to use the new version. The SFST version is still available through the web page above, but it is not developed any further.
TRmorph is being developed with foma. It should also be trivial to compile it using HFST tools as well (since HFST uses foma as back end). Compiling with Xerox tools should also be possible (if you have to) with minor modifications regarding limited reduplication implemented using foma's _eq().
What is new in this version:
- This is a complete rewrite using more-familiar Xerox languages lexc/xfst. - A completely new lexicon, semi-automatically constructed using web corpora and online dictionaries. (more work is needed, though) - A revised tag set. - A few more utilities: stemmer, unknown word guesser, segmenter, and a hyphenation tool. - A manual, in progress, but it is still usable. - New license: this version of TRmorph is distributed under GNU Lesser General Public License  (also see the file LICENSE).
If you use this analyzer in your research, and want to cite it, please (still) cite the following paper:

You can get the latest version of TRmorph from GitHub here:

repository using git, and pull often since this version is
changed relatively frequently, but GitHub also allows you to download

The compilation requires foma and a C preprocessor (gcc preprocessor
is used by default), and make, and a few more UNIX tools. Assuming you
have foma installed, type
make to compile the analyzer. If all
goes well, you should have a binary automaton in foma format called
trmorph.fst. After that you can use interactive
for batch processing (both are part of foma). Here are some examples:
$ foma ... foma: regex @"trmorph.fst"; 2.3 MB. 53564 states, 149484 arcs, Cyclic. foma: up okudum oku<v><past><1s> foma: down oku<v><past><2s> okudun foma: exit $ echo "okudum" |flookup trmorph.fst okudu oku<v><past><1s>
There are also separate automata for segmentation, stemming (or lemmatization) and hyphenation that you can compile and use.
