RESUMO

The large number of data generated by people and organizations has stimulated the research on effective and automatic methods of knowledge extraction from databases. This dissertation proposes two new bioinspired techniques, named cPSC and oPSC, based on the Particle Swarm Optimization Algorithm (PSO) to solve data clustering problems. The proposed algorithms are applied to data and text clustering problems and their performances are compared with a standard algorithm from the literature. The results allow us to conclude that the proposed algorithms are competitive with those already available in literature, but bring benefits such as automatic determination of the number of groups on the dataset and a search for the best partitioning of the dataset considering an explicit cost function.
