Hi Josh & all, Tks for the suggestion about the output search graph! I'll use it once I totally understand. Currently, I'm using n-best-list with alignment info to derive the different translation choices from a particular src words/phrases, which is for simplicity.
After reading through the Moses webpage, I think what I'm interested in is a *confusion network* (CN) representation instead of a word lattice one. Thus, I have a few concerns, hopefully someone could help me answer them :) : 1) representation: the CN derived from the output search graph would mean edges between two consecutive nodes correspond to different translation of the same src/word phrase? If so, am I right that we will obtain multiple CNs from an output search graph since there's multiple ways of segmenting the source input. 2) CN for n-best list: if we want to extract CN network for an n-best list, is that in the search graph, we need to traverse to those last hypotheses in different search paths, and pick up those with top scores? It looks like there's some redundancy as the moses option to extract n-best list 's already done that? 3) ConfusionNet in Moses code: could I make use of this to obtain the ConfusionNet at the end of the decoding process? If so, where should I start, I mean the classes?
