Cluster analysis is commonly used in several areas. However, even the most recent approaches present dificulties that limit its use by experts of different areas. This research project is related to the development of a new approach to cluster analysis aiming at the obtaining of a greater variety of potentially useful clusters than that obtained by the traditional approaches or the more recent ensemble and multi-objective alternatives. The proposed approach aims at been a mechanism to obtain all (or most of) the relevant clusters hidden in one data set, regardless the structure they belong to (a partitition, for example). In order to achieve this, we look for clusters regardless the refinement level they occur, the clustering criteria they satisfy or if they are partially overlaped. In summary, the goal is to give the most complete possible description of the data in order to facilitate the work of the experts in the data, thus increasing the amount of knowledge they can extract using one single tool.
