PerfectMatch is a tool used by SDL TMS to pre-translate files. PerfectMatch takes translations from previously translated versions of the same document, or other documents from the same folder structure, and applies the translations to identical segments in new tasks.
PerfectMatch also checks segments for context match as well as source text match. PerfectMatch is performed during the pre-processing workflow stage when files in new jobs are being prepared for translation.
A segment translated by PerfectMatch is a 100% match and is locked automatically.
