1. A computer-implemented method comprising:

  • accessing, at a computing device including a processor, a translation hypergraph that represents a plurality of candidate translations, the translation hypergraph including a plurality of paths including nodes connected by edges;

    calculating, at the computing device, first posterior probabilities for each edge in the translation hypergraph;

    calculating, at the computing device, second posterior probabilities for each n-gram represented in the translation hypergraph based on the first posterior probabilities; and

    performing, at the computing device, decoding on the translation hypergraph using the second posterior probabilities to convert a sample text from a first language to a second language,where calculating the second posterior probabilities includes calculating;
