Ant-based extraction of rules in simple decision systems over ontological graphs
Krzysztof Pancerz, Arkadiusz Lewicki, Ryszard Tadeusiewicz
Abstract
In the paper, the problem of extraction of complex decision rules in simple decision systems over ontological graphs is
considered. The extracted rules are consistent with the dominance principle similar to that applied in the dominance-based
rough set approach (DRSA). In our study, we propose to use a heuristic algorithm, utilizing the ant-based clustering
approach, searching the semantic spaces of concepts presented by means of ontological graphs. Concepts included in the
semantic spaces are values of attributes describing objects in simple decision systems.
