Numerical Analysis in Conceptual Systems with ToscanaJ

  • Peter Becker
Part of the Lecture Notes in Computer Science book series (LNCS, volume 2961)


Toscana-systems have been used in many contexts to visualize information found in relational databases. As opposed to many other approaches this is done based on conceptual structures rather than numerical analysis. While conceptual structures often tend to ease understanding of the data by avoiding too much information reduction, sometimes a particular reduced information gained by using numerical approaches is preferable. This paper discusses how conceptual structures and numerical analysis can be combined into conecptual information systems using ToscanaJ.
