Depfix is a system for automatic post-editing of English-to-Czech machine translation outputs, mostly created by Rudolf Rosa within his Master Thesis. It focuses especially on grammatical errors (typical for SMT systems). Depfix uses a Treex pipeline of NLP tools to provide language analysis and generation; the core of Depfix are 28 correction rules (such as "change the gender, number and case of each adjective to match its head noun").

For instructions on installing and running Depfix, go to Using Depfix.
