Hypertext 2009
This is the network of facetoface contacts of the attendees of the ACM
Hypertext 2009 conference. The ACM Conference on Hypertext and Hypermedia 2009
(HT 2009, http://www.ht2009.org/) was held in Turin, Italy over three days from
June 29 to July 1, 2009. In the network, a node represents a conference
visitor, and an edge represents a facetoface contact that was active for at
least 20 seconds. Multiple edges denote multiple contacts. Each edge is
annotated with the time at which the contact took place.
