Dear Sir,

I am trying to train the model for tree to string. For this I have
generated the input corpus into desired xml format as mentioned on
moses website. I did this using mxpost tagger and collins parser. So
my sentence look like

<tree label="TOP"> <tree label="S"> <tree label="NPB">  <tree
label="CD"> One </tree> </tree> <tree label="VP"> <tree label="VBZ">
gets </tree> <tree label="NPB"> <tree label="NNP"> happy </tree>
</tree> <tree label="PP"> <tree label="IN"> with </tree> <tree
label="NP-A"> <tree label="NPB"> <tree label="DT"> a </tree> <tree
label="NN"> visit </tree> </tree> <tree label="PP"> <tree label="TO">
to </tree> <tree label="NPB"> <tree label="DT"> the </tree> <tree
label="NNP"> Taj </tree> </tree> </tree> </tree> </tree> </tree>
</tree> </tree>

Now, I tried to trained the model using the command

$SCRIPTS_ROOTDIR/training/train-model.perl -scripts-root-dir
$SCRIPTS_ROOTDIR -root-dir tr2str -corpus tr2str/corpus/my.lowercased
-f en -e hi -alignment grow-diag-final-and -lm
0:5:$PWD/tr2str/lm/my.lm -hierarchical -source-syntax
tr2str/corpus/my.parse.en > tr2str/training.out

The command terminates successfully. But, my extract and rule-table
files are empty. So, when I try to translate anything I get nothing as
output. I even tried to first convert the input into parsed xml format
and then decode it, but this too did not work.

Kindly help me to resolve this issue.

Thank you.

Sincerely,
Nisheeth
