  7. TopicLens: Exploring Content and Network Structure in Parallel(Devendorf, O’Donovan, Hollerer) Hybrid Network Views • River and Graph representations displayed in parallel. • River shows statistical (topic modeled) information about network selections. • Graph view shows information about the underlying network.

  8. Visual Analysis of Dynamic Topics and Social Network in Parallel Network Data Sources (APIs etc) LDA over Content Topology Analysis LDA Topics Sub-Networks Sub-Networks Graph View River View

  9. TopicNets: Exploring Topic Relations in Social Networks • LDA “Topic Models” useful for understanding relations in large volumes of text. • Visualization and Interaction can help a user gain insights into topic modeled data. • LDA can be iteratively applied to tailor the information space to a users requirement. • Gretarsson, O’Donovan et al. 2011 (ACM Trans. On the Web)
