What does B-ASP mean in ATEPC dataset? Some are B-ASP-999 and some are B-ASP sentiments, so what's the difference?

yangheng95 commented 2 years ago

-999 is used as padding, have no sentiment. B-ASP or I-ASP should not be followed by -999 (Positive, Negative, etc. instead) in any dataset, if you find so, please report.

I'm sorry, but what does B-ASP mean and I-ASP mean?
