HFST: Dictionaries

This is a list of dictionaries and other language models or rulesets compiled and usable with HFST tools.

Morphological analysers

For morphologically simple languages a dictionary can be made of a word-form list which can be compiled to an HFST transducer with the simple tool hfst-fst2strings. More complex morphologies require tools that support more elaborate formalisms, e.g. LexC, TwolC, Xfst or SFST-PL.

HFST tools contain clones for all xerox finite-state morphology tools: hfst-lexc, hfst-twolc, hfst-xfst and hfst-compose-intersect. This listing shows the freely available language descriptions that have been compiled on these HFST tools.

The HFST tools also contain a parser for SFST-PL formalism, copied verbatim from also freely available SFST tools, called hfst-sfstpl2fst This list contains all free SFST morphologies that compile with HFST port.

Ready-compiled versions of the morphologies listed here are (or will be soon) available in HFST download pages.

The Swelex morphological analyser for Swedish is based on Den stora svenska ordlistan (copyright (c) 2003 Tom Westerberg) and is distributed under the Creative Commons ShareAlike 1.0 license.

The Swelex sources and ready compiled transducers can be fetched from the HFST download pages The Swelex file is named hfst-swedish.tar.gz.

The file swedish.hfst contains the morphology in the standard hfst format and swedish.hfst.ol in the optimized lookup format. The directory src contains Krister Lindén's scripts to build Swelex.

Dictionaries (for spell-checking)

There're preliminary scripts for converting hunspell dictionaries to HFST automata. While hunspell dictionary format was later extended for morphological analyses, majority of dictionaries do not take advantage of this and it is not yet implemented for HFST.
