Bill,

I agree with Ian that the current exercise, from my point of view, was 
about getting a "feel" of the "syntax" associated with various 
representations, not about immediately designing a "meaningful" 
structure within any given framework. The various ad hoc choices in the 
other examples illustrate that, and raise interesting questions worth 
discussion.

On the other hand, you are asking very interesting and relevant 
questions, so let me briefly reply.

Exactly. So even though there is no chance to have a unified emotion 
theory any time soon, there is *some* consensus among *some* people, and 
we should provide a flexible mechanism for encoding that, without 
deciding for a camp ourselves. And if engineers decide they need to 
build bridges between camps that theorists would never endorse as valid, 
but for which there is an application need, we should let them. 
Actually, maybe, just maybe, the experience of what works and what 
doesn't in practice can inform theory...!

Yes. BUT in order to avoid complete chaos, there should be clearly 
defined ways of saying that one is "using Ekman's six basic emotions" or 
"the concept of mood dimensions as in Gebhard 2007" or "the distinction 
of types of affective states as in Scherer 2000" etc. So the idea is, 
let them use what they want *if* they make their choices explicit.

In EARL, we did this using a separate namespace for each configuration 
of annotations [1] -- not very modular (you could not simply refer in 
the document itself to the various label sets you were using, but needed 
to create a new Schema for every specific combination), but OK it was a 
start.

This is another really good question. We should talk about it. For 
machine recognition and generation, of course both the generation and 
the interpretation of the markup will be done by software components; 
but for manual labelling of data, what would one use? I know that for 
annotating videos, colleagues in Paris and Belfast are using Anvil [2], 
but that labelling tool has its own data formats, so getting an Emotion 
Markup from Anvil may need effort.

One important aspect is extensibility: we will not be able to preview 
all the sets of emotion categories, for example, that our users will 
want to use in their annotations. Often, these are quite 
application-specific, so users will want to "plug in" their own label set.

So if I understand you correctly, this is a stub of a graphical 
representation of an OWL document containing a concrete emotion 
annotation. "annotatedEmotion" is where the Emotion Markup really 
starts, right? The line from *"Out damn spot!" to *Annotation24601 is an 
answer to our requirement 'Links to the "rest of the world": Links to 
media'.

I am not very firm in ontological theory, so I am uncertain about the 
status of *FearInstance35: is this the specific emotion annotated in 
this case, never to be used again, or is it an "instance" in the sense 
that it is one particular kind of combination of a categorical label and 
other annotations?

Also, the way that you structure it, *FearInstance35 being an 
"instanceOf" *DC-2006-Fear, doesn't that imply you are giving more 
fundamental reality to the categorical representation compared to the 
"valence" dimension (which is not, in the example, derived from any 
particular theory)?

So much for now, best regards,
Marc
