The Third Machine Translation Marathon, which will take place January 26-31 in Prague, Czech Republic, is hosting a Open Source Convention to advance the state of the art in machine translation.

We invite developers of open source tools to present their work and submit a paper of up to 10 pages that (a) describes the underlying methodology and (b) instructions how to use the tools. We are looking for stand-alone tools and extensions of existing tools, such as the Moses open source systems. Accepted papers will be presented during the MT Marathon and published as a special issue of the Prague Bulletin of Mathematical Linguistics (http://ufal.mff.cuni.cz/pbml).
