by Chris Callison-Burch (Released: June 12, 2009)

This document gives instructions on how to install and use the Joshua decoder. Joshua is an open-source decoder for parsing-based machine translation. Joshua uses the synchronous context free grammar (SCFG) formalism in its approach to statistical machine translation, and the software implements the algorithms that underly the approach.

These instructions will tell you how to:

1. Install the software
2. Prepare your data
3. Create word alignments
4. Train a language model
5. Extract a translation grammar
6. Run minimum error rate training
7. Decode a test set
8. Recase the translations
9. Score the translations
