The session started with a “demo madness” – five demos presented in five minutes (altogether) – just teasers but I found it very helpful to decide what I should have a closer look at. Here my “decission”:
- BubbleBoard: a visual answering machine – touchscreen, annotations, possibility to arrange messages … very nice
- SONAR: social network aggregation
More to come after I have visited the demos.
And then the papers in the session:
- “Tag-based Metonymic Search in an Activity-centric Aggregation Service”, Michael Muller (IBM): activity-centric collaboration history: instant collaboration, activity explorer, unified activity management, Lotus Connections Activities (commercial software now); it is about connecting awareness/alerts with objects; problem: activity flood (“yet another inbox”); problem: too many inboxes/information/activity overload; we need an activity-based aggregation service; very interesting/important work!; Malibu “surf board” to address these problems; input is external feeds (RSS, ATOM, SNA, …); in the demo he showed aggregation from activities, bookmarks (Dogear) and external feeds with links into IBM Blue Pages (social networking service); I surely will have a closer look at this … and I really have to install Lotus Connections soon – it is on my todo list for too long now ;-)

- “Bringing Round-Robin Signature to Computer-Mediated Communication”, T. Nishida: background: chat system as a back channel during presentations at conferences; problem with missing anonymity; pros and cons of anonymity; goal: exploring the design space between anonymity and non-anonymity: round-robin signature (a kind of group signature): protocol: anonymous post – other users can support post – if post gathered sufficient number of supporters names of the supporters are revealed as a round-robin signature; hypothesis: this protocol has the best properties of anonymous and non-anonymous discussions; prototype application: Lock-On-Chat
