Many sources of bitexts have been identified; some examples are: • texts from multilingual institutions, such as the Hansards corpus (Roukos et al., 1995) or the Europarl corpus (Koehn, 2005); • translations of software interfaces and documentation, such as KDE4 and OpenOffice (Tiedemann, 2009); or • news translated into different languages, such as the SETimes corpus (Ljubešić, 2009), or the News Commentaries corpus (Bojar et al., 2013).
one of the most obvious sources for collecting parallel data is the Internet.
