The Beta4 release of the Stanford Phrasal open source machine translation package has just been released!

About

Stanford Phrasal is a state-of-the-art phrase-based machine translation system. It provides an easy to use API for implementating new decoding model features and supports unique capabilities such as translating using phrases that include gaps (Galley et al. 2010) and conditional extraction of phrase-tables and lexical reordering models.

Mailing Lists

We have 3 mailing lists for Stanford Phrasal, all of which are shared with other JavaNLP tools (with the exclusion of the parser). Each address is at @lists.stanford.edu:

1. java-nlp-user This is the best list to post to in order to ask questions, make announcements, or for discussion among JavaNLP users. You have to subscribe to be able to use it. Join the list via this webpage or by emailing java-nlp-user-join@lists.stanford.edu. (Leave the subject and message body empty.) You can also look at the list archives.
2. java-nlp-announce This list will be used only to announce new versions of Stanford JavaNLP tools. So it will be very low volume (expect 1-3 message a year). Join the list via via this webpage or by emailing java-nlp-announce-join@lists.stanford.edu. (Leave the subject and message body empty.)
3. java-nlp-support This list goes only to the software maintainers. It's a good address for licensing questions, etc. For general use and support questions, please join and use java-nlp-user. You cannot join java-nlp-support, but you can mail questions to java-nlp-support@lists.stanford.edu.
