Data and their clustering

This master thesis descripes known methods of data clustering and examines their possible application on data from the area of social networks. Because of this we recapitulated how we describes objects using data and which technics we use for specifying their similarity. After that we recapitulated known clustering methods and possibilities of their validation. Consequently we have suggested method how perform clustering in the social networks and we tested it. We have applied this method on data from the area of international trade in 2008. We have evaluated and summarized results of this experiments. In the end of this work we have suggested possibilities of further research in this area
