Copenhagen.
The first main session at the COST298 conference is on interdisciplinary design, and begins with a presentation by James Stewart and Laurence Claeys. They ask how speculative research for innovation can be conducted within interdisciplinary frameworks. Problem here include that different disciplines work within very different time scales (e.g. rapid prototyping vs. long-term observation of users), that they use different mental models, and that disciplines tend to under-value one another and misuse one another's research approaches.

Following the next09 conference last week, I've now made my way to Copenhagen, to attend the COST298 conference with the somewhat unwieldy title "The Good, the Bad, and the Challenging" - don't hold that against it, though: the actual theme of the conference (and of the COST298 EU research programme) is participation in the broadband society, so it should be interesting. (The two-volume proceedings alone are going to seriously push my luggage weight over the edge on the flight back.) Also, erm, interesting is the choice of location, at Aalborg University's campus in Ballerup on the outskirts of Copenhagen, almost an hour's metro ride out of town - I must say I much preferred the IT University campus, just cross from the city centre, where we held the AoIR conference last year.

The next presentation here at next09 is by Rafi Haladjian from Violet, a company founded in 2003 in Paris. He says that the new frontier for future developments is no longer cyberspace, but meatspace - the physical world. There is a life after the PC...

But how do we get there? Violet's first step was to create the world's first Internet-connected, wi-fi, toy rabbit (think robotic, not fluffy). This also demonstrated that everything is now possible, no matter how absurd - if you can network rabbits, you can connect anything. In effect, the rabbit blinks, moves, speaks, reads, sings, hears and 'smells' (using RFID); it is an ambient information device which acts as a spontaneous information provider for short 'goot to know', real-time, information and snack media, and as a multi-expression messenger which can be controlled over the Internet.

Day one at next09 ends with a humorous review of tweets on Twitter, by the team from TwitKrit, a German blog offering 'literary criticism' of Twitter posts. Those of you who are so inclined will know how to find #next09 comments on Twitter - or otherwise, pop in to the next09 community at SixGroups.

(Speaking seriously for a moment, though - a conference presentation compiled from random Twitter users' outstanding tweets raises some very interesting questions about the boundaries between public and private. Discuss.)

The final keynote on this first day of next09 is by Matthias Schrader of next09 conference organisers Sinnerschrader, who brings us back to the conference theme 'share economy'. What can we share, what do we want to share, what do we get out of sharing?

In the share economy, what we share are in the first place the tools we use; using (physical, mechanical) tools, of course, has long been seen as a uniquely human trait (although that belief has now been shown to be mistaken - other animals use tools, too). Perhaps the next step from here is the belief that only humans use tools to create other tools - that is, that only humans innovate by combining small, modular, commodity tools into more complex, composite, cutting-edge 'meta-tools'.

The final full session here at WebSci '09 is on (Greek) politics online, so of course I'm here. It's another session with live interpretation from Greek to English - hopefully she's done chewing gum now! We start with G. Alexias, who introduces us to the performance of Greek political parties online (and he does so in English, actually). Does the online presence of Greek political actors lead to the formation of online political communities? His study examined this in the wake of the 2004 parliamentary elections, and performed both a quantitative analysis of social software features of these sites and a qualitative analysis of the sites' characteristics.

The cultural convergence session at WebSci '09 continues with a panel composed of Greek musicians, actors, and directors. Electronic musician Konstantinos Bita, who began his work on Ataris and Amigas, reflects on his introduction to digital technology, and the gradually growing importance of electronic networks - using modems at first, and then connecting more directly to the Internet. In the early days, access was often free, but then commercial interests began to build their walled gardens with the aim to enrich themselves; with Web 2.0, Konstantinos believes, a further change will occur which further isolates people and locks them into online pursuits without providing real sociality.

The second and last day of WebSci '09 starts with a session on social networking, although the first paper in this session, by Yorgos Amanatidis, has the somewhat technical title "Kernels for Complex Networks" - we'll see what that's all about... Visual network graph models, apparently, for graphs which represent relational data in an abstract way. Such graophs can be used in the analysis, simulation, and prediction of network topologies, focussing especially on aspects like scaling, clustering, and node centrality.

What can be observed in real networks is the degree distribution: as the Web grows, the average degree is constant, but there is huge variance and no concentration around the average; indeed, we see the small world phenomenon which produces networks with small diameter and strong clustering tendencies (the friend of my friend is likely also to be my friend). Kleinberg, for example, modelled the fact that in small world networks there are not only short paths between nodes, but that these nodes can find such paths effectively using local information.

Finally for this first day at WebSci '09, we move to the poster session, which includes our poster on the Australian political blogosphere mapping project; the A1 poster itself is available here, and there's also a brief article to provide further background detail. From the post slideshow that's playing at the moment, there's quite a bit of really interesting stuff here - and all of the posters are also available online.

The final talk here at WebSci '09 is presented by Nick Papanikolau, whose interest is in communicating online risk more effectively to users, by drawing on lessons learnt from cognitive science. Online risks may include direct risks from user-to-user interaction as well as more indirect threats through viruses and malware - such threats are generally intangible, and user interface design may help make them more tangible.

Online security is now a concern to everyone, of course, but not everyone has a sufficient perception of the threats and risks which they are exposed to. The potential repercussions, however, are vast, and include the loss or theft of data as well as unauthorised access to it. In the offline world, there is substantial information on how humans perceive danger and risk, and this has been applied in a variety of ways (for example in communicating health risks and other medical advice) - but it does not necessarily translate directly to the online context, because of the comparative lack of tangibility.
