      Hi Georgianna, thank you for reaching out. There was some system maintenance today, is it working for you now?

    When will you make a Rusyn translator? I would love to see that.

    1. Petro Orynycz (Петро Оринич) Avatar

      Thanks for your interest in the project, Aleksandar. Work on the translator for Rusyn as codified in Slovakia will start as soon as the Lemko translator achieves a near-human or superhuman bilingual evaluation understudy (BLEU) score. Hopefully soon!

    Just a question, what is the difference between Lemko and Rusyn?

    1. Joseph Avatar

      Geography, dialect + accent. Lemko as a subset of RUSYN.
      Take the above as opinion. 🙂

    Lemko is very close to Polish. Was Lemko Polonized?
