If multiple options are given here, then mulitple tables are generated, in fact all possible combinations. Typically you do not want so many reordering tables, but the training and the decoder would support this. > Should not --reordering be required to specify exactly the same number > of reordering types as there are factor pairs in --reordering-factors? > (A bin confusing might seem the fact that in --reordering, the main > delimiter is s comma, while in --reordering-factors, the main delimiter > is s plus.)

Yes. That's very intuitive, isn't it? > Can one *disable* plain distance-based reordering? (Not that I would > want to do that, I just want to know the configuration options. Syntax > of moses.ini does not seem to think about this option.) No, that's not possible. You can essentially turn it off by giving it weight 0. -phi _______________________________________________ Moses-support mailing list [email protected] http://mailman.mit.edu/mailman/listinfo/moses-support
