If that case, the problem would not be in DBpedia interpretation, but in 
Wikipedia categorisation, which should change then to, well, say "Dating 
profile"?. The real problem here is to know if TimBL has only one 
identity, defined by a single URI (or the set of all its owl:sameAs 
equivalents), to which a consistent set of assertions can be attached. 
Seen at the level of current DBpedia, the answer is assumed to be "yes". 
But the more precisely you will look at it, the more you will need to 
split this so-called individual in a cluster of avatars (the child, the 
student, the CERN engineer, the tax-payer, the patient, the Web 
inventor, etc ...), which will at some point need different URIs and 
different descriptions if you want to keep some consistency. That will 
happen first in Wikipedia, when an article will be split in several 
ones, because the subject description has gained in complexity and 
accuracy. I guess DBpedia will synchronise, but what will happen to 
deprecated URIs? Astronomers know that, a single star to the naked eye 
is a multiple system in instruments, the number of components growing 
with the power of the instrument. In brief, looking closely at any thing 
leads most of the time to the loss of its identity/individuality. This 
fractal and evolving nature of reality we'll need to take into account 
in our systems, when semantics go beyond the naive notion of the world 
as a set of well-identified, pre-existing things.

We've just started scratching the surface of all this I'm afraid.
