I don't see any reason why a lattice should contain an EPSILON edge.

In a confusion network, EPSILON are needed to allow the translation of input of different lengths.
The sausage structure of the CN imposes the same amount of source words,
and the EPSILONs overcome this constraint.

This is not the case for lattice, because you can have any number of edges/words in a complete source path.


cheers,
Nicola

I'm just looking at the lattices decoding, as implemented in moses.

for confusion networks, it's fair to have EPSILON words (that represent blank words). However, I don't see the point of them in lattices.

Anyone have an opinion? How is it implemented in cdec & joshua?

I've updated the bjam code so that Moses compiles on cygwin 64-bit.

https://github.com/moses-smt/mosesdecoder/commit/f65786534a1ad19e76f9192d2811e4c2fc3c675d

when compiling on cygwin, Moses compile successfully but the unit tests
reports errors. These can be ignored.

boost unit testing isn't supported on cygwin for some reason.
