I'm currently using Gephi as an analytic tool for ethnographic work that I'm doing concerning a single forum thread. I've tried a few Google Scholar searches about previous work mapping out a single thread, but haven't had luck turning up anything. My current plan of approach is to have each poster be one type of node (a poster node, identified by being one color) and each of their posts to the thread being another type of node (a post node, identified by being another color). Each post a poster makes is connected by an undirected edge between those two entities. If one post refers to another post then thre's a directed edge between them.
This has worked out fine for my preliminary analysis, but I'm starting to wonder if there's official methodology for this that I've missed in my searching. Has anyone run across any academic work done on mapping out social relations in individual forum threads?
