Hi Rakesh,
It looks like you are trying to build a hierarchical translation model
with part-of-tags as additional factors. Looking at the archives from
moses-support, there were a couple of threads previously where Philipp
mentioned the lack of support for factored models in the hierarchical
chart decoder. You can find links to these threads, both of which are
about a couple of years old.

May be Hieu / Barry / Philipp can confirm if this is still the case?
Does Moses support factored models for hierarchical models (and the
chart decoder) ? If it does, are there any restrictions on the type of
steps that can be used in decoding (Generation?).
having factors should work. I haven't tried it but Phil Williams has, I
think. If it doesn't please let me know and I'll fix it.
Generation steps aren't implemented. If you need them, let me know

Hi,
My EMS with following settings, *crashes at build-generation stage*.
/
input-factors = word pos
