Dear colleagues,

We have just made available a new metric ACT "Accuracy of Connectives Translation", a MT metric specific for connectives translation. This is a free, open-source tool under GPL v3  license (available on github). It was built using Perl, so it runs on any platform:

http://www.idiap.ch/software/act

ACT is a reference-based metric to measure the accuracy of discourse connective translation. The metric relies on automatic word-level alignment (using GIZA++, or not ) between a source sentence and respectively the reference and candidate translations, along with other heuristics for comparing translations of discourse connectives.  Using a dictionary of equivalents, the translations are scored automatically, or, for more accuracy, semi-automatically.  The accuracy of the ACT metric was assessed by human judges on sample data for English/French, English/Arabic, English/Italian and English/German translations; the ACT scores are within 2-4% of human scores.

We would like to maintain and further develop the ACT metric porting it  to other language pairs and to other linguistic phenomena (verb tenses, pronouns, etc) that still pose problems for current SMT systems, so if your are interested to extend it to other new language, let us know. 

Best regards

Najeh Hajlaoui
