1. Instructions on a computer-usable medium wherein the instructions when executed cause a computer system to perform a method of statistical machine translation (SMT), said method comprising: receiving a word string in a first natural language; parsing said word string into a parse tree comprising a plurality of child nodes; reordering said plurality of child nodes to provide a plurality of reordered word strings; evaluating each of said plurality of reordered word strings using a reordering knowledge, wherein said reordering knowledge is based on a syntax of said first natural language; and translating a plurality of preferred reordered word strings from said plurality of reordered word strings to a second natural language based on said evaluating; and selecting a statistically preferred translation of said word string from among translations of said plurality of preferred reordered word strings.
