Semi Supervision or Weak Labelling?

The problem with bots is the drift is so fast on identifying them from content that they post. The real way to go at it is to network, to do a graph analysis and to understand why certain bots interact with the same content. Don't worry so much about the content as the activity. Once you find a small botanet begin to analyze their activity. You don't want to label the accounts themselves. You want tolabel the activity and then the connectivity between bots.
