Spatial Visualisation of Conceptual Data
Michel Soto, Bénédicte Le Grand, Marie-Aude Aufaure · 2009
Numerous data mining methods have been designed to help extract relevant and significant information from large datasets. Computing concept lattices allows clustering data according to their common features and making all relationships between them explicit. However, the size of such lattices increases exponentially with the volume of data and its number of dimensions. This paper proposes to use spatial pixel-oriented and tree-based visualisations of these conceptual structures in order to optimally exploit their expressivity.
