Members of the MT community may be interested in knowing, if they do not always do so, that the German Research Center for Artificial Intelligence (DFKI) is offering the Logos Machine Translation System in an open-source derivative known as OpenLogos. OpenLogos runs on the Linux platform with PostgreSQL and maybe downloaded from http://logos-os.dfki.de/
This open-software offering is being made to individuals, universities and public institutions free-of-charge, with a view to its exploitation in both current and new language combinations.
OpenLogos is based upon the long-standing commercial, rule-driven Logos System owned by GlobalWare AG (Eisennach)

For those interested in knowing about the underlying linguistic technology of OpenLogos, the article Bernard (Bud) Scott: The Logos Model: An Historical Perspective. In: Machine Translation 18 (2003), pp. 1-72 provides a comprehensive overview of the Logos approach to machine translation.
An earlier on-line description of the linguistic and computational motivations for the Logos Model is available at http://iai.iai.uni-sb.de/iaien/iaiwp/p11/index.html

[NLP around NYC] free toolkit for syntax-driven SMT
The 2005 JHU Language Engineering Workshop has released a free toolkit for syntax-driven statistical machine translation (a.k.a. "translation by parsing"). The "GenPar" Toolkit is intended to serve as a springboard for research. Its modular design makes it also useful for educational purposes.
GenPar features:
* User, system, and design documentation.
* Flexibility -- it is dynamically configurable via nested config files.
* Intuitive, object-oriented design, making it easy to modify and extend.
* Complete validation suite.
* Fully integrated prototype SMT systems for 3 language pairs. These prototypes are certainly not state-of-the-art (so far). However, they are complete, in the sense that no additional software is required to build an MT system, apply it to new input, and automatically evaluate the results. These prototypes can also serve as blueprints/templates for other language pairs.
GenPar is downloadable from here:
http://www.clsp.jhu.edu/ws2005/groups/statistical/GenPar.html
The accompanying "MTV" tool for visualizing tree-structured alignments is downloadable from here:
http://www.clsp.jhu.edu/ws2005/groups/statistical/mtv.html
A report outlining the context in which these tools were created is at
http://www.clsp.jhu.edu/ws2005/groups/statistical/documents/finalreport.pdf
Researchers at several institutions are actively developing GenPar and MTV. We welcome inquiries from potential contributors and collaborators. Of course, we also welcome feedback from users.
