Mapping Nominal Values To Numbers For Effective Visualization, Geraldine Rosario, Elke Rundensteiner, David Brown, Matthew Ward
Mapping Nominal Values To Numbers For Effective Visualization, Geraldine Rosario, Elke Rundensteiner, David Brown, Matthew Ward
David C. Brown
Data sets with a large number of nominal variables, some with high cardinality, are becoming increasingly common and need to be explored. Unfortunately, most existing visual exploration displays are designed to handle numeric variables only. When importing data sets with nominal values into such visualization tools, most solutions to date are rather simplistic. Often, techniques that map nominal values to numbers do not assign order or spacing among the values in a manner that conveys semantic relationships. Moreover, displays designed for nominal variables usually cannot handle high cardinality variables well. This paper addresses the problem of how to display nominal …
