Depfix is a system for automatic post-editing of phrase-based English-to-Czech machine translation outputs, based on linguistic knowledge. We analyzed the types of errors that a typical machine translation system makes, and created a set of rules and a statistical component that correct some of the errors. We use a range of natural language processing tools to provide us with analyses of the input sentences. Moreover, we reimplemented the dependency parser and adapted it in several ways to parsing of statistical machine translation outputs. We performed both automatic and manual evaluations which confirmed that our system improves the quality of the translations.
