... possible derivations of a parse tree contribute equally to the total probability of the parse tree. This is equivalent to saying that there is a hidden component to the model, and that DOP can be ... complicated by the presence of subtrees of depth greater than 1. To derive the reestimation formula, it is useful to consider the state space of all possible der...
