Thanks, the prototype helps make some this more concrete.
I am increasingly wondering if "uncertainty" will be overloaded here. People
seem to want to use it for various types of measurement uncertainty (e.g. the
standard error), ranges with no defined central value, and distributional
summaries (e.g. max and min), as well as for the precision with which a value is
entered (as in the "auto-certainty" value in the prototype). These are all
quite different beasts, and conflating them will probably lead to problems -
The idea is to allow for the detailed information as qualifiers, while using the
"conflated" uncertainty for query answering. Ideally, for queries, we need a
single value. The current solution would be use a single value plus a range of
uncertainty for answering queries, so "Primates taller than 1m" will include a
species said to be 90+/-20cm or something.
