Reputation Systems and the Mobile Web

Athens.
For the first round of paper sessions here at WebSci '09, I've chosen a session on trust and distrust. Having just watched people juggle USB drives for the best part of 15 minutes, we finally start with a presentation by Dave Karpf. His interest is in the Web's impact on collective action for Internet-mediated organisations - and he suggests that the emergent mobile Web wll be of particular importance in this context.

Mobile Web-enabled devices enable new forms of collective action; rating and reputation systems attach track record data to individual participants - when the two meet, this has potentially radical implications for what uses become possible. Reputation in this context refers to complex, context-dependent community assessments; it plays a crucial role in solving collective action problems, and introduces what Axelrod has called a 'Shadow of the Future': they lead people to do well for others as they make visible the contributions of each participant (and introduce possible future repercussions for those who fail to put in). This is visible for example in communities like eBay or Slashdot, which both promote positive and sanction negative contributions through their reputation systems. Even Google's PageRank can be understood as a reputation system: PageRank measures, indirectly, reputation.

What Is Web Science?

Athens.
The first full day here at WebSci '09 begins with a keynote by NIgel Shadbolt, founding director of the Web Science Research Initiative (WSRI). As we're in Athens, he begins by taking the historical approach: he notes that another way to describe Web science is as 'philosophical engineering', which links back ultimately to the founding fathers of philosophy, including Socrates, Plato, and Aristotle. Their pure philosophical speculation, indeed, formed the basis not only for modern philosophy, but also for modern science.

The Future Web: A Systems Design Perspective

Athens.
The second keynote this evening is by Joseph Sifakis, who begins by taking us through a quick tour of the history of informatics - starting with Turing and Gödel in 1936 and moving through information systems, graphic interfaces, the emergence of the Web and the information society, and leading today to the increasing embedding of computing systems into all kinds of technologies. In the future, we'll see further developments in computing power and storage capacities, and this means that computing systems will be literally everywhere. In developed countries, in fact, a person already uses some 250 different processors per day - processors in cars, computing equipment, home entertainment, telecommunication systems, and so on.

From the World Wide Web to Web Science

Athens.
Tonight I'm at the opening session for WebSci '09, and we're looking forward to a keynote by Sir Tim Berners-Lee, on the twentieth anniversary of his invention of the World Wide Web. The conference itself is going to be opened in the presence of none other than the president of Greece, though, so the place is swarming with Greek police (unsurprisingly, given the continuing low-level unrest in the country). In fact, there's a couple of secret service agents coming through right now, earpiece and all. His Excellency himself is running fashionably late.

Chinese Mobile News, Australian Bloggers, and Youdecide2007: Publications Roundup

Time to catch up with a few publications - my recent work is featured in a number of new collections:

Mobile Technologies: From Telecommunications to Media, edited by Gerard Goggin and Larissa Hjorth, collects some of the best papers from the Mobile Media 2007 conference (which I blogged about at the time) in Sydney. Looks like a fabulous collection, and I'm delighted that an article by former QUT Visiting Scholar Liu Cheng and me about SMS news in China has been included. We're looking especially at the experience at Yunnan Daily Press, where Cheng led the roll-out of SMS news functionality, and we're including some staggering statistics about the growth of Internet and mobile use in China as well (I wonder how they'll be affected by the global financial crisis...).

CRC, CCi, CoE, QUT... New Roles, More Acronyms

Looks like my email footer is about to grow by a couple of lines: late last week I accepted an offer to take on the role as project leader for the Social Media project in the Smart Services CRC, following the swift footsteps of Darren Sharp, who's moving on into an industry position. I've already been involved as a researcher in a number of projects within the CRC - and our first few outputs from this work should become available on the CRC Website in the not-too-distant future -, but in this new role I'll have a great deal more responsibility for seeing our current Social Media projects through to completion, and supporting the development of the next round of projects.

Coming Up: Athens and Frankfurt

In just over a week, I'm off to Europe for the first of a number of conference trips this year; as always, I'll try to blog my progress as I go. My first stop is the WebSci '09 conference, where I'm presenting a poster on the background to our blog mapping project (which has already produced papers at the AoIR and ISEA conferences last year, with more to come). Should be interesting, even if it's a lot more (computer and social) science-y than what I'd usually attend. And, they've got Tim Berners-Lee as a keynote speaker - no doubt in honour of yet another anniversary, and one which I didn't even mention in my post the other day: yes, the Web, too, first happened 20 years ago (or at least that's when Sir Tim first proposed his hypertext transfer protocol)!.

Wanted: Your Views on Online News (Win an iPod!)

Just a quick announcement (more blogging to come soon, promise!) - one of the research teams at the Smart Services CRC that I'm participating in is currently running a survey about Australians' use of online news. Please participate, and pass on the link: http://tinyurl.com/digitalnews. One lucky respondent will win an iPod!

There's more to come from the CRC soon, incidentally - the first few major reports from the Audience and Market Foresight and Social Media research streams will be released shortly...

1989, Then and Now

For the world, 1989 was a momentous year. East Germans take to the streets in weekly protests. Poland's Solidarnosc is legalised, and later wins the Polish elections. Hungary defortifies its border with Austria, sparking a wave of defections from Eastern bloc nations to the West. Czechoslovakia's velvet revolution ends decades of communist rule, and Václav Havel is elected president. Romanian dictator Nicolae Ceauşescu is forced from power. And the Berlin Wall comes down, quite literally, in small pieces and large chunks. Also that year, Chinese troops crush the Tiananmen Square protests. George Bush the elder becomes US president, Ayatollah Khomeini dies, and Kurt Waldheim becomes president of Austria, while the last Soviet tanks leave Afghanistan and the rise of Slobodan Milosevic's nationalists begins in Yugoslavia. And in Australia, Andrew Peacock succeeds John Howard as opposition leader. That, at least, is what the history books and annual digests will tell you.

Hello TiVo - Goodbye TiVo?

I've spent some time last year (and I hope to do more of it in 2009) talking and writing about the increasing challenge to traditional television which the growing online video sector poses - both in terms of the original content available from the likes of YouTube and Current.tv and in terms of the shared and re-broadcast television content available from Justin.tv and various bittorrent networks.

My argument in that context was that such online services are gradually becoming more convenient than television itself, even where it's enhanced through VCRs, DVRs, TiVos, iPod Videos and other time- and space-shifting devices. Well, as it turns out, younger television audiences at least in the US agree with me. The Wall Street Journal reports that a new study by Solutions Research Group found that
