As ken says, the input sentences to Moses SCFG decoder has <s> and </s>.
To do the Chiang-style glue rules: <s> [X] </s> ||| <s> [S] </s> ||| 1 ||| ||| 0 [X][S] [X][S] [X] ||| [X][S] [X][S] [S] ||| 2.718 ||| 0-0 1-1 ||| 0 to do ITG-style gleu grammar, just add [X][S] [X][S] [X] ||| [X][S] [X][S] [S] ||| 2.718 ||| 0-1 1-0 ||| 0 However, as ken also says, Chiang's glue grammar gives slightly worse model score than Moses' default glue grammar.
