Ant-based clustering for flow graph mining
Arkadiusz Lewicki, Krzysztof Pancerz
Abstract
The paper is devoted to the problem of mining graph data. The goal of this process is to discover possibly certain sequences
appearing in data. Both rough set flow graphs and fuzzy flow graphs are used to represent sequences of items originally
arranged in tables representing information systems. Information systems are considered in the Pawlak sense, as knowledge
representation systems. In the paper, an approach involving ant based clustering is proposed. We show that ant based
clustering can be used not only for building possible large groups of similar objects, but also to build larger structures (in
our case, sequences) of objects to obtain or preserve the desired properties.
