I would like to know if there are any well known patterns or industry
efforts to solve semantic heterogeneity.
Example from Prof. Amit Sheth Paper:
Consider an attribute MEAL_COST
of relation RESTAURANT in database DB1 that describes the average cost
of a meal per person in the restaurant without service charge or tax.
Consider attribute by the same name (MEAL_COST) of relation BOARDING
in database DB2 that describes the average cost of a meal per person
including service charge and tax. Let both the attributes have the
same syntactic properties. Attempting to compare attributes
DB1.RESTAURANT.MEAL_COST and DB2.BOARDING.MEAL_COST is misleading
because they are semantically heterogeneous.
I know there are several individual research efforts. I would also
appreciate if any senior researchers could point me to some serious
ontology management development efforts.
Thanks in Advance.
