can you please show me your moses.ini files, the exact command you are
using to do force decoding.
Also, can you send me few lines of your input file and your reference file.

Hi All,
I am trying to implement forced decoding procedure of (Weubker et al
2010) using Moses constrained decoding functionality for a
Arabic-English bitext of ~1 million sentence. For start, I am using
Moses to decode a sample of 20000 sentences from this bitext. Though I
have tried to relax all the parameters to as maximum as possible, I
haven’t been able to obtain a coverage of more than 50%. I am
describing below models and the parameters I have used and their
maximum/minimum value :
1. Phrase table built from the same bitext using moses training
(grow-diag-final-and algorithm) (~60 million phrase pairs)
2. Distortion penalty, phrase penalty
3. No LM or reordering models. Infinite distortion limit
4. ttable limit : 1000000
5. Stack size (maximum : 3000)
6. Beam size (10^(-10) to 10^(-30) (min))
7. Stack diversity : 0-1
Some of them I have used as discussed in this report
(http://www-labs.iro.umontreal.ca/~foster/papers/forcedecode-techrep12.pdf
<http://www-labs.iro.umontreal.ca/%7Efoster/papers/forcedecode-techrep12.pdf>)
Can anyone explain if I am missing any other parameters set to default
in moses that I should relax to increase my coverage ? Or what are the
default values of all possible parameters in moses ?
Thanks and Regards
Praveen
