Can FLExTrans help me translate between any two languages?

FLExTrans works best between related languages. In theory, you can translate between any two languages, but big linguistic differences mean lots of work to get translation working.

Do I have to have FLEx lexicons in order to use FLExTrans?

FLExTrans needs FLEx lexicons for the source and target languages. If you don’t have these, you can gradually build lexicons as you go.

How is FLExTrans different from statistical machine translation system like Google Translate?

Statistical systems like Google Translate rely on huge amounts of data for a given language pair. With this data models are created that make a statistical prediction of what a word or sentence translates to. FLExTrans does not rely on large amounts of data like this. Instead FLExTrans is a rule-based system. With lexicons in the source and target languages and a set of rules that specify how the source language gets transformed into the target language, FLExTrans can produce accurate translations. FLExTrans is tailor-made for low-resource languages where there is not a lot of language data available.

Can I work on multiple language pairs with FLExTrans?

Yes, you can make a copy of the FLExTrans installation folder and start working on a new language pair in that folder. The work you do for the new language pair will not affect work in your original language pair. Of course, if a shared FLEx project is used, changes in that project will affect any language pair that uses it.
