HFST ospell</h1>
<p>
HFST ospell is a free open source spell-checker using weighted
finite-state automata. It is a light-weight library for using
combinations of two automata–a language model and an error model–for
spell-checking and correction.
</p>
<p>
It has optional support for XML-based metadata using libxml++2 or
tinyxml2. Automata compression is supported through libarchive,
currently with zip format.
</p>
<p>
The API of the library is stable to support updating the shared library
while keeping the automata and the plugins for enchant and LibreOffice
in place. The <a href="doc/html/">api documentation</a> is maintained with
doxygen.
</p>
<p>
You can download the library and small demo applications from
<a href="http://hfst.sf.net/">HFST’s main sourceforge site</a>.
