[Sigia-l] Bottoms-up tagging

[Listera]

I admit that sounds like an unnatural act but... :-)

Tom Coates (BBC Radio and Music Interactive) describes it so:

The concept is really simple - there are concepts in the world that can be
loosely described as being made up of aggregations of other smaller
component concepts. In such systems, if you encourage the tagging of the
smallest component parts, then you can aggregate those tags up through the
whole system. You get - essentially - free metadata on a whole range of
other concepts.

...But music radio shows can be loosely understood as a collection of songs,
and music radio networks can be equally understood as a collection of shows.
So if ten songs that are well-rated and tagged with 'alternative' and 'pop'
are played on one specific radio show, it's quite plausible to argue that
the show itself could be automatically understood as being tagged with
'alternative', 'pop' and that it should be considered well-rated. Similarly
if all the shows are equally tagged with 'alternative', then it's likely
that you could describe the network that broadcasts them as an 'alternative'
station.

I'm working on a rating+tagging model for a vertical market with faceted
interplays, so I'm curious about this subject matter. Tom wants to know if
you

"can you think of any other heirarchies or places where we could encourage
the tagging of the smallest practical component part and then derive value
from aggregating up the semantic chain? Could the same thing work for
non-heirarchic relationships?"
