MtJaen

Japanese English Machine Translation

This page describes the Jaen MT system, an MT system based on the [wiki:LogonTop LOGON architecture], using [wiki:JacyTop Jacy] for the source language analysis and the [wiki:ErgTop ERG] for the target language generation. In order to degrade gracefully in the presence of input we cannot yet translate, we are also working on a backup [wiki:MtJaenSmt Statistical MT system] based on [http://www.statmt.org/moses/ Moses].

Jaen is the elder sibling of [wiki:NoJa Noja], the Norwegian-Japanese MT system.

The first version of Jaen is described in:

• Francis Bond, Stephan Oepen, Melanie Siegel, Ann Copestake, and Dan Flickinger (2005)
  • [http://www2.nict.go.jp/x/x161/en/member/bond/pubs/2005-summit-osmt.pdf Open source machine translation with DELPH-IN]. In Open-Source Machine Translation: Workshop at MT Summit X, pp 15--22, Phuket.
