The Hspell Project
"Life, liberty, and the pursuit of spelling errors."

The Hspell project is a free Hebrew linguistic project.

Its primary goal is to create a free Hebrew spell-checker. We have already achieved that goal, and you are invited to Download the latest version of the spell-checker. It is free software, licensed under the GNU Affero General Public License (AGPL v3).

In addition to a spell-checker, the project also produced a Hebrew morphological analyzer, which for every valid Hebrew word lists all of its possible readings (valid combinations of prefix and inflected base word), and for each reading describe its part-of-speech, gender, tense, and other attributes.

The secondary goal of the project is to make the algorithms and dictionaries, created initially for the spell-checker, freely available. These could be used in more sophisticated research or applications that require Hebrew word lists or a Hebrew morphology engine.

Such potential application areas might include search engines, speech synthesis, and much much more. The availability of a free basis will hopefully encourage free development on top of it, to the benefit of the general Hebrew-speaking population.

Hspell was written by Nadav Har'El and Dan Kenigsberg.
