2. A translation method using at least one phrase pair having a source phrase in a first language and a target phrase in a second language, comprising: receiving, at a computer having one or more processors, a test phrase pair including a test source phrase and a test target phrase; determining, at the computer, at least one primary phrase including at least one of a primary source phrase, a primary target phrase, or both, based upon a primary source score, a primary target score, or both, wherein the primary source phrase with the test target phrase comprises a primary source phrase pair that has a score equal to at least the primary source score, and the primary target phrase with the test source phrase comprises a primary target phrase pair that has a score equal to at least the primary target score; comparing, at the computer, the at least one primary phrase with the at least one test phrase; and modifying a machine translation system based upon the results of the comparing the at least one primary phrase with the at least one test phrase.
