EdiMTAATS is a collection (two is a collection, right? And there's more in the works, too. Just stay tuned ...) of web-based tools for the annotation and alignment of parallel and multi-texts.
Version 1 of a tool for human evaluation of machine translation output based on semantic frames and their slot fillers.
The first in the bunch, developed by Ulrich Germann (2007,2008) while he was at the University of Toronto. Yo momma of all the tools in this collection. Yawat is a tool for manual word alignment in parallel text. An online demo is avaliable here.
