Here's an example of what I mean by wanting things to "just work" -- and
wanting the categories to be relatively transparent by default. If you type
in "bike" into this element-search thingie,
http://www.lugnet.com/dbtoys/elementsearch/?=bike
it fails to find any pieces labeled as "bike." But it does have some pieces
labeled "bicycle," "motorcycle," and "trike," and it knows that these are
categories and they are related to a "bike" category. So it shows you:
80% Bicycle
60% Motorcycle
36% DUPLO Tricycle w/ Hitch
15% Three-Wheel Motor-Bike
It's guessing that you probably mean "bicycle" when you say "bike," but it
wants to show you some other possibilities just in case you really meant
"motorcycle" or "dirt bike" or "three-wheeler."
The category/attribute associations are defined in this example as:
bike ===>
80% bicycle
60% motorcycle
40% trike
so that the "Three-Wheel Motor-Bike" (which is listed as being 25%
"motorcycle") shows up as only being 15% "bike." (60% of 25% = 15%)
Now if you really wanted bicycles, and you entered "bicycle", then you'd
only get this one result:
100% Bicycle
and it tells you that there's a category called "bicycle" which is a
sub-category of "bike." Ideally -- as you suggested in the Santas example
-- it would notice that motorcycles and three-wheelers are similar to
bicycles and give links to those categories as siblings of "bike" (or some
other derivation path).

p.s. Larry: When we met in In August, you suggested that two-way fuzzy
references probably ought to accommodate separate fuzzy-values in each
direction, just in case it was ever needed. At the time, we couldn't come
up with any real-life examples. But maybe here's one: If you're assocating
the set "female" with the set "woman" (this example DB has these for female
minifigs and the Belville mom), isn't it true that all women are female but
not all females are women? That is, "woman" is a 100%-subset of "female"
while "female" is perhaps only a 75%-subset of "woman" in the LEGO world.
I need to re-read Kosko on the subject of super-sets being fractional
subsets of the smaller sets they themselves contain, but I think this might
actually be a real example of what we were wondering about...
