  In this expository paper we give an overview of some statistical methods for
the monitoring of social networks. We discuss the advantages and limitations of
various methods as well as some relevant issues. One of our primary
contributions is to give the relationships between network monitoring methods
and monitoring methods in engineering statistics and public health
surveillance. We encourage researchers in the industrial process monitoring
area to work on developing and comparing the performance of social network
monitoring methods. We also discuss some of the issues in social network
monitoring and give a number of research ideas.
