7. A method of translating a source corpus in a source language into a target language using a language translation rule set comprising at least one treelet translation pair and at least one language order template on a computer having a processor, the method comprising: executing on the processor instructions configured to: parse the source corpus to identify element types for respective source corpus elements; generate a parse tree mapping the source corpus elements; select at least one treelet translation pair mapping at least one source corpus element to at least one target corpus element; select language order templates corresponding to unordered source corpus elements; and generate a target corpus according to the parse tree, selected treelet translation pairs, and selected language order templates.
