It 's tricky. It 's tricky because one could well imagine  I think it will turn out to be the case that uh , this thing we 're talking about , th the extended n uh knowledge modeler will fill in some parameters about what the person wants.

You could well imagine you get to a point where it 's got a  a choice to make and it just doesn't know something.
Mm - hmm.
And so y you would like it t also be able to uh formulate a query. And to run that back through uh. the dialogue manager and to the output module and back around.
hmm
