Welcome to Moses!

Moses is a statistical machine translation system that allows you to automatically train translation models for any language pair. All you need is a collection of translated texts (parallel corpus). An efficient search algorithm finds quickly the highest probability translation among the exponential number of choices.

Features

• Moses offers two types of translation models: phrase-based and tree-based
• Moses features factored translation models, which enable the integration linguistic and other information at the word level
• Moses allows the decoding of confusion networks and word lattices, enabling easy integration with ambiguous upstream tools, such as automatic speech recognizers or morphological analyzers
• The Experiment Management System makes using Moses much easier

Get started

The released software includes a command line executable which can used for decoding. The source code for the decoder, can be downloaded from github. Download the latest release or the current snapshot from github.

Learn about the decoder, training models, and tuning. Follow the step-by-step guide to build a baseline translation system. The documentation available at this web side is also compiled in a printable manual.
