Hi Philip,
Thanks for your kindly and professional replying. I think your
answers are correct. But I have one point not totally clearly.
For rule c: [X][S] </s> [X] ||| [X][S] </s> [S] ||| 1 ||| 0-0 ||| 0
In the left side, does the first [X][S] mean the source side target must be
"X" and the target side target must be "S" at the same while?
You explained rule c as: S -> X </s>, S </s>
Can it be fully explained as: X/S -> X </s>, S </s>
I am a fresh guy for mose hierarchical model. Thanks for your answering in
patience.
Best Regards,
Jun Lang
