SECOND CALL FOR PAPERS OPEN SOURCE TOOLS FOR MACHINE TRANSLATION The Fourth Machine Translation Marathon, which will take place 25–30 January 2010 in Dublin, Ireland, is hosting an Open Source Convention to advance the state of the art in machine translation. The MT Marathon is organised by the National Centre for Language Technology and the Centre for Next Generation Localisation at Dublin City University on behalf of the EuroMatrixPlus Consortium. 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) includes 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). Possible Topics: • training of machine translation models • machine translation decoders • tuning of machine translation systems • evaluation of machine translation • visualization, annotation or debugging tools • tools for human translators • interfaces for web-based services or APIs • extensions of existing tools • other tools for machine translation This is the second time that the MT Marathon will host the Open Source Convention. The papers from last year are available online: http://ufal.mff.cuni.cz/pbml-91-100.html Papers will be reviewed by two reviewers appointed by the program committee.
