In one embodiment, a translator quality assurance system may rate a translation using a mapping chart. A data interface 150 may access a translation dictionary matching a source language to a target language. A processor 120 may map automatically a sentence pair having a source sentence 310 in a source language and a target sentence 320 in a target language at a linguistic level using the translation dictionary. A user output device 170 may display a translation quality report of the target sentence 320.
