Dominance-Based Rough Set Approach for decision systems over ontological graphs
Krzysztof Pancerz · 2012
In the paper, we continue the research in the field of decision systems over ontological graphs. Some relations defined over attribute values in such systems are partial order relations. Therefore, we try to incorporate Dominance-Based Rough Set Approach (DRSA) for decision systems over ontological graphs. Due to this approach, we can define decision rules, similar to that defined in DRSA, which give us a new look on data included in such systems.
