Babelscape/mrebel-base · mrebel-base output interpretation

Hi team,
Thanks for the work you have put in the model.

Upon running the base model on example text, I get following output:

text: text = 'The Red Hot Chili Peppers were formed in Los Angeles by Kiedis, Flea, guitarist Hillel Slovak and drummer Jack Irons.'
output seq:
__en__ __sv__ Red Hot Chili Peppers __vi__ Los Angeles __tn__ location of formation</s>
__en__ __sv__ Hillel Slovak __uk__ Red Hot Chili Peppers __vi__ part of</s>
__en__ __sv__ Red Hot Chili Peppers __vi__ Los Angeles __tn__ location of formation __sv__ Kiedis __uk__ Red Hot Chili Peppers __vi__ part of</s>

How to interpret the separators like dunder-en , dunder-sv, dunder-vi, dunder-uk etc?

My end goal is to finetune mrebel-base for triplet extraction in English?

Thanks in advance.
