Multilingual parallel documents (pardocs) are translations of each other. For example, publications of the European Union in 24 languages. This is about how to automate the production of pardocs based on the simultaneous generation of all the linguistic versions from one template and parallel segments.
To avoid misunderstanding: generation of pardocs is not about machine translation (MT) or computer aided translation (CAT). It is about processing already translated parallel segments into documents. MT and CAT might be used in creating parallel segments.
