PS. What would be very useful to

explanation (/proof) mechanism available with the results - so when
"population US" is solved by a "Semantic Web search and

what

semantic-web@w3.org...
How about the explanation/proof mechanism in the Internet Business Logic
system [1] ?
Here's part of an explanation that is automatically generated by the
system:
estimated demand 523 in NJ is for 1000
gallons of product-y in October of 2005
for estimated demand 523 0.19 of the order will be product-x from
Shell Canada One
1000 * 0.19 = 190
--------------------------------------------------------------------------------------------------------------------
for demand 523 NJ for 1000 product-y we use 190 product-x from
Shell Canada One
estimated demand 523 in NJ is for 1000 gallons of product-y in October of
2005
for demand 523 for product-y refinery Shell Canada One can
supply 300 gallons of product-x
for demand 523 the refineries have altogether 1600 gallons of acceptable
base products
300 / 1600 = 0.1875
0.1875 rounded to 2 places after the decimal point is 0.19
------------------------------------------------------------------------------------------------------------------------------
for estimated demand 523 0.19 of the order will be product-x from
Shell Canada One
estimated demand 523 in NJ is for 1000 gallons of product-y in October of
2005
in October an order for product-y can consist in whole or part of
product-x
in October the refinery Shell Canada One has committed to
schedule 300 gallons of product-x
we have truck transportation from refinery Shell Canada One
to region NJ
-------------------------------------------------------------------------------------------------------------------------------
for demand 523 for product-y refinery Shell Canada One can
supply 300 gallons of product-x
You can see the actual explanation by pointing a
browser to [1] and running the example called Oil-IndustrySupplyChain1
.
Some background is in [2,3].
Thanks in advance for
comments.
