Dependence between components in natural systems is a well studied phenomenon in the form of biological and social networks. The concept of community structure arises from the analysis of social networks and has successfully been applied to complex networks in other fields such as biology, physics and computing. We provide empirical evidence that dependence between statements in source cod
The concept of community structure arises from the analysis of social networks in sociology. Community structure can be found in many real world graphs other than social networks. Recently, efficient community detection algorithms have been developed which can cope with very large graphs with millions of nodes and potentially billions of edges. So, for the first time, there is the potential for investigating communities in real industrial-strength software at the statement level.
