Re: another relevant bit of ontology

The paper seems to be discussing deductive rule-based reasoning with sensor
data. While this is definitely useful for certain tasks (i.e., checking
constraints and data validity) it may be insufficient for other purposes
such as interpretation and explanation of sensor data. For example, the rule
on page 5 says that if the temperature is less than zero Celsius then it
must be winter.  But, is it winter because it is cold, or is it cold because
it is winter? Or is it cold because the sensor is in a freezer?
Interpretation of observations seems more like an abductive task, where
there are often multiple hypothetical explanations for a set of sensor data.
Just a suggestion in case inference over observation data fits into the
scope of this project.  For reference please see:
