This paper introduces the Memetic toolkit for recording the normally ephemeral interactions conducted via internet video conferencing, and making these navigable and manipulable in linear and non-linear ways. We introduce two complementary interaction visualizations: argumentation-based concept maps to elucidate the conceptual structure of the discourse using a visual language, and interactive event timelines generated from the meeting metadata. We discuss in detail the affordances of Memetic's tools, in particular the Compendium hypermedia mapping tool, and the Meeting Replay tool that renders the semantic navigation indices into the videoconference replays. Additionally, with respect to methodology and evaluation, we describe how we are engaging diverse end-user communities in the process of designing and deploying these tools.
