Genomic comparison using Data Mining techniques based on a possibilistic fuzzy sets model

Current copiousness of genomic information stored in biological databases makes ultimately feasible the proposal for an application of knowledge management aimed to discover general rules in subcellular phenomena. The goal of this work is primarily to discover relationships between genes by microarray analysis. The tools exploited come from clustering techniques and are mainly based on KDD (Knowledge Discovery in Databases) concepts. Starting from a data set, each element can be represented by a characteristic matrix, which sums up all data attributes. In this case data mining is oriented to perform a Pattern Recognition of related sequences, hidden in databases. Following a bottom up approach, the next refinement is to compare retrieved data to gather similar features, by dedicated clustering algorithms, driven by fuzzy logic, allowing us to perceive by intuition a common denominator for various genomic families and to anticipate likely future developments.
