On 2011-06-11 Hieu added a check in Parameter.cpp to verify that each parameter in the ini file is a real, valid, known parameter. Prior to that, I guess unknown parameters were silently ignored. I looked through the history of Parameter.cpp and StaticData.cpp going back to the first revision of Moses on sourceforge, and didn't find any mention of a ttable-threshold parameter. Based on that, and the fact that the parameter appears to have been present at the JHU summer workshop (http://www.statmt.org/jhuws/?n=Experiments.EPPS) I'm assuming that ttable-threshold was a Pharaoh parameter that was removed or renamed prior to Moses being put up on Sourceforge. If anyone knows, I would still be interested in knowing if ttable-threshold was removed or if it was renamed to something else. Thanks, Lane Schwartz
