FLExTrans is linguist-friendly machine translation because a central component is the intuitive application Fieldworks Language Explorer (FLEx). This application serves as the repository for lexicons, the place where entries are linked and the tool for the analysis piece of the analysis-transfer-synthesis-style system. Apertium, the well-established open-source machine translation platform, is used for the transfer piece of the system and STAMP for the synthesis piece. The linguist’s role is to analyze the source text with FLEx, link lexicon entries and write transfer rules to do either word or syntactic-level translation.
