Ariadne. Introduction Ariadne is a Java-based plug-in to the Eclipse IDE that visualizes the social networks present in distributed software projects. Ariadne builds a call-graph from an Eclipse project using an appropriate call graph generator. After creating the call-graph, Ariadne automatically connects to the configuration management repository associated with the project to retrieve authorship information about the project. With this information, it creates a structure called a "social call-graph", or a call-graph annotated with authorship information. From the "social call-graph", Ariadne generates a sociogram and can display it as a graph using Prefuse .
