Hebrew is probably the toughest language to handle in text retrieval systems. Thankfully, HebMorph is up for the challenge! See live demo here!
As big believers in open-source software, HebMorph is an open-source software under the AGPL3 license. This basically means if your code is released as open-source, you are free to use HebMorph however you'd like (although we will appreciate a mention!).
If you are developing a commercial application, please contact us to discuss a commercial license. This helps us support development of future versions that make Hebrew search even better. Paid licenses are bundled with a proprietary dictionary, which replaces the AGPL3'd hspell used by the open-source version, as well as integration support.
Check out the series of blog posts that started it all: Challenges with indexing Hebrew texts (HebMorph, part 1), Finding Hebrew lemmas (HebMorph, part 2) and Open-source Hebrew information retrieval (HebMorph, part 3). The project's roadmap is in the last part.
For latest updates on the project see posts in the blog on this domain that are tagged HebMorph.
Our entire code base is available to all on GitHub, under the AGPL3 license: http://github.com/synhershko/HebMorph.
What is this all about? Creator of HebMorph, Itamar Syn-Hershko, explains in this short conference talk (Hebrew):
Buzzilla, one of our clients, are using HebMorph to enable effective Hebrew search. See how they are using HebMorph to enable both Google-like search experience, and also laser-beam approach to search in Hebrew texts despite the huge challenges the language presents:
