Helsinki Finite-State Transducer Technology (HFST)

GNU LGPL

The Helsinki Finite-State Transducer software is intended for the implementation of morphological analysers and other tools which are based on weighted and unweigted finite-state transducer technology. This work is licensed under a GNU Lesser General Public License v3.0.

The feasibility of the HFST toolkit is demonstrated by a full-fledged open source implementation of a Finnish lexicon as well as a number of other languages of varying morphological complexity (OMor).
