14. A computer-implemented system for assigning a score to the ordering of a target language dependency structure given a source language dependency structure and an alignment between nodes in the source language dependency structure and the target language dependency structure, the system comprising: a subsystem including an order model configured to assign a score to an order of child nodes depending on a parent node in the target language dependency structure, given a plurality of source nodes in the source language dependency structure and an alignment between the nodes in the source language dependency structure and the target language dependency nodes, wherein the target language dependency structure comprises a target language dependency tree and wherein the source language dependency structure has nodes aligned with the nodes in the target language dependency tree, and wherein the order model is configured to compute a score indicative of whether a selected node in the target language dependency tree will switch from being a pre or post modifier of a parent node in the source language dependency structure to being a post or pre modifier of the parent node in the target language dependency tree, wherein the subsystem is configured to be deployed in a machine translation system.

The system of claim 14 wherein the order model computes a probability for the order based on a plurality of features comprising at least some of a set of features including: target words corresponding to the dependent nodes and the parent node, source words aligned to the target words, positions of the source words in the source language dependency structure, and part-of-speech of each of the source and target words.
