abstract = {In this paper we introduce Self-Organizing Map-based
techniques that can reveal structural cluster changes in two related
data sets from different time periods in a way that can explain the new
result in relation to the previous one. These techniques are
demonstrated using a real-world data set from the World Development
Indicators database maintained by the World Bank. The results verify
that the methods are capable of revealing changes in cluster strucure
and membership, corresponding to known changes in economic fortunes of
countries.},
