Query: GED: the method for group evolution discovery in social networks   The continuous interest in the social network area contributes to the fast
development of this field. The new possibilities of obtaining and storing data
facilitate deeper analysis of the entire network, extracted social groups and
single individuals as well. One of the most interesting research topic is the
dynamics of social groups, it means analysis of group evolution over time.
Having appropriate knowledge and methods for dynamic analysis, one may attempt
to predict the future of the group, and then manage it properly in order to
achieve or change this predicted future according to specific needs. Such
ability would be a powerful tool in the hands of human resource managers,
personnel recruitment, marketing, etc.
  The social group evolution consists of individual events and seven types of
such changes have been identified in the paper: continuing, shrinking, growing,
splitting, merging, dissolving and forming. To enable the analysis of group
evolution a change indicator - inclusion measure was proposed. It has been used
in a new method for exploring the evolution of social groups, called Group
Evolution Discovery (GED). The experimental results of its use together with
the comparison to two well-known algorithms in terms of accuracy, execution
time, flexibility and ease of implementation are also described in the paper.
