“…Then, the interventions are deployed with different methodologies, hardware and software configurations and network structures (client and server). In contrast, from the research point of view, the soft computing technique, such as Artificial Immune System (AIS), evolutionary computation techniques namely Particle Swarm Optimization (PSO) and ant colony optimization, Deferential Evaluation (DE) and Genetic Algorithm (GA) have been well incorporated in order to increase or enhance the accuracy of spam detection (Mohammad and Zitar, 2011;Wu et al, 2011). This will increase the percentage of classification, which is one of most important areas in data mining (Hong, 2011).…”
