HICSS 2011 Paper: EventGraphs: Charting Collections of Conference Connections

A recent paper “EventGraphs: Charting Collections of Conference Connections” by Social Media Research Foundation members Marc Smith (from Connected Action), Professor Derek Hansen (College of Information Studies) and Professor Ben Shneiderman (Computer Science/Human Computer Interaction Lab) both from the University of Maryland and has been published at the 2011 Hawaii International Conference on System Sciences (HICSS) conference.  This is the 44th year for the conference. Derek Hansen presented the paper on January 7, 2011.

The paper is about visualizing social media and it describes the visualization of the patterns of connections formed when people tweet about events like conferences and news stories.

EventGraphs are social media network diagrams constructed from content selected by its association with time-bounded events, such as conferences. Many conferences now communicate a common “hashtag” or keyword to identify messages related to the event. EventGraphs help make sense of the collections of connections that form when people follow, reply or mention one another and a keyword. This paper defines EventGraphs, characterizes different types, and shows how the social media network analysis add-in NodeXL supports their creation and analysis. The paper also identifies the structural and conversational patterns to look for and highlight in EventGraphs and provides design ideas for their improvement.
