Thanks Ales ! It works. Yes, I think I had misunderstood the mapping section. I am still not clear about the step index that you mentioned, shall check it out.
The generation table is indeed from part of speech tags to words. Here is a snapshot, conj yet 0.0001612 0.1165049 conj both 0.0029155 0.1998158 conj since 0.0031305 0.2045654 conj that 0.0624614 0.5230648 conj if 0.0111111 1.0000000 conj whilst 0.0002150 1.0000000 conj like 0.0002956 0.0161290 conj or 0.0949617 0.9970377 conj soon 0.0001881 0.0474576 Best Regards, Sriram On Fri, Apr 5, 2013 at 11:28 AM, Ales Tamchyna <[email protected]> wrote: > Hello Sriram, > > I think you misunderstand the [mapping] section of moses.ini (I don't know > if it's documented anywhere though, apart from the source code). > > The first number specifies the decoding path, the second number is the > step index.
