In simple words.
The current decoder reads in a L1-L2 phrase table only.
What can I do so that:

I can read phrase pairs from 2 phrase tables L1-L3 and L3-L2 and then construct 
phrase pairs for L1-L2 at decoding time itself?

Source-Pivot and Pivot-Target phrase tables 
 
hi raj

i don't really understand what you want to do. Perhaps give an example. Or 
better yet, just try to do it yourself and ask specific questions when 
something break

Hello,
I am currently doing research on using pivot languages for Phrase based SMT.

My current method involves the usage of alternate decoding paths feature to 
combine multiple  synthesized Source-Target phrase tables. (I have noticed that 
not many people exploit this method or even if they do.... they don't mention 
it clearly).

However pre-synthesized  phrase tables need to be pruned to remove low 
probability phrase pairs and I would like                 to generate phrase 
pairs via a pivot at run time. I am ok with taking additional decoding time.

I am aware that Bertoldi (2008) had already mentioned that he had used this 
method but this is not present in the moses decoder release.
I would very much like to implement this but do not know where to start.
If someone could tell me the section of code that reads in phrase pairs given a 
source phrase I think I might be able to do something.
Any help would be appreciated.

Thanks in advance.
