On Context (again)

Seeing as Ricky is fixated on the hard and fast defintion of context to the exclusion of all else I will stipluate that I agree with Ricky's quotation of Dey et al's defintion of context:

Context is any information that can be used to characterize the situation of an entity. An entity is a person, place, or object that is considered relevant to the interaction between a user and an application, including the user and applications themselves.

I will go even further to say that I agree with Ricky on this point also:

So how does an application decide what is relevant, without being pre-configured with a static set of entities that the programmer/administrator/user has deemed to be relevant to the scenarios in which the application will be used? Now there's a real research problem.

Of course, I have more to say, but it can wait. (Don't you hate it when someone leaves you hanging like that?) Tune in tomorrow for Context Wars: revenge of the big words.
