Re: [EMOXG] Deliverable report published as first draft: Emotion Markup Language: Requirements with Priorities

Hi Bill (and all),

thanks for making these points. The [0,1] approach is the 
technically most practical and most obvious, which probably is the 
reason nobody else stumbled over the applicability issues raised by you.

I think I do agree with you that [0,1] is not sufficient to properly 
specify an emotion's intensity. At least it might not be feasable 
for some use cases for reasons provided by you.

Your class-based approach sounds very attractive to me. Actually {0, 
..., 1} are possible classes which would allow easy mapping to the 
[0,1] standard representations used for other attributes. But other 
classes (low, medium, high ...) are also imaginable which would need 
to be specified, probably along with information on how to map them 
to [0,1] scales.

Specification of the classes used (and mapping rules) would need to 
be done as meta information then, which means that we would need to 
add it to section 2.2: Meta-information about emotion annotation I 
guess?

What do others think?

Christian
