Jane is an open source toolkit for hierarchical phrase-based translation. The hierarchical phrase model is an extension of the standard phrase model, where the phrases are allowed to have ``gaps''. In this way, long-distance dependencies and reorderings can be modelled in a consistent way. As in nearly all current statistical approaches to machine translation, this model is embedded in a log-linear model combination.
RWTH has been developing this tool during the past years and it was used successfully in numerous machine translation evaluations. It is developed in C++ with special attention to clean code, extensibility and efficiency. The toolkit is available under an open source non-commercial license. Currently, only Linux (x86 and x86-64) platforms are supported.
The development of Jane is ongoing. A manual is available in pdf format. It is not yet fully completed but it provides enough information for installing Jane, training systems and producing translations.
Publications of the i6 chair about the theoretical foundations and methods used can be found in the publications page.
Jane is available only in source form. See the corresponding chapter in the manual for build instructions.
A set of installed tools and libraries is required:
