Aug 2008 Microsoft Techtalk: Social Network Visualisation

MS IrelandOn Monday the 25th of August I gave an invited Techtalk on Social Network Visualisation at Microsoft Ireland. I was invited to present by Andrzej after meeting him at AVI 2008 in Naples Italy in June.

The talk discussed the history and purpose of social network analysis and visualisation. I also gave details on a range of interactive visual representations (algorithms and methods) for abstract relational data. This visual display of data aids in human exploration and understanding of it. It is a key research
challenge. Network Visualisation is concerend with the sourcing, management, layout, drawing, viewing and interaction with relational data.

Visualisation relies on a human to guide the application of methods, structuring of queries and control of the interaction in the pursuit of understanding. In practice, the network data of interest arises from domains including social science (criminal networks, transaction networks, standard social networks, phone-call networks and disease transmission networks), bioinformatics (metabolic networks and protein-protein interaction) and ICT (computer networks, software calls and neural networks). The essential idea in relational information visualization is that the a person’s perceptual abilities are employed to understand and explore such information. Visually, humans can perceive more patterns linking local features in the data.

While research in other fields such as data mining, machine learning and knowledge management are also attempting to aid in the analysis of such voluminous data, there is a realisation that the “human-in-the-loop” visualisation affords a visual analysis of data not possible through automation alone.

Network visualisation is a broad topic so to help contextualize it I limited the scope to social networks. As such, the focus of this talk is to survey the fundamental algorithms, methods and interaction techniques along with research in my own group required to visualise large and dynamic social networks.
