The final speaker in this session at AoIR 2009 is Anatoliy Gruzd, whose focus is on the communities of blog readers, and how such communities of people discussing shared issues across different blogs may be discovered automatically - that is, how the social networks connecting them may be identified. This is important not least because of the massive growth in online information - we need to develop better tools to extract salient material from this overload of content, and to do so, knowing the social context is paramount.

The next presentation at AoIR 2009 is by Hallvard Moe, who begins by noting that the public sphere is still a useful concept It exposes us to expressions, opinions, and perspective we would not otherwise have chosen in advance, and provides a range of common experiences for citizens. But how do online media impinge on this - do they segment and polarise the public sphere (as suggested by people like Cass Sunstein), or provide more connections between and access to different ideas (as per Yochai Benkler's networked public sphere)?

The final speaker this morning at AoIR 2009 is my PhD student Tim Highfield, who focusses on the French blogosphere and uses much the same methodology as in our joint paper. His work focusses on a dataset of French blog and mainstream news media posts from some 450 sites throughout 2009, and out of this identifies what events and topics are driving discussion. Sites in his sample were identified through searches on relevant search engines as well as on specialist blog aggregators such as the French Linkfluence.

Overall, this particular study, which focusses on blogs, now takes in some 23000 posts from 148 active blogs over 221 days, out of some 165,000 posts when you also include the mainstream news media. Because the French political environment is multi-party, these blogs cluster into a number of groupings, rather than just a broad 'left' and 'right' category.

OK, I'm up next at AoIR 2009, as part of a blog concept mapping double-header with my brilliant PhD student Tim Highfield. Here's the Powerpoint - hope the audio recording works out, too... and the audio is attached now, too.

The next speakers in the blogging session at AoIR 2009 are Muhammad Abdul-Mageed and Priscilla Ringrose, whose focus is on war blogging. Such blogging addresses the exceptional communication demands during war situations, and war bloggers in warzones can meet these needs speedily and with authority. This also reflects a continuing shift in the media overall. The focus of this paper is on the 2006 war between Israel and Lebanon, where western media profiled (English-language) Israeli and Lebanese blogs.

So, the bloggers here belonged to two oppossing, warring nations,and espoused different ideological positions; how were they chosen and what positions do they reflect? What demographics, structural features, thematic, regional, and political positioning do they exhibit? According to which parameters were they selected? The study analysed all posts from 40 blogs (20 Israeli, 20 Lebanese) during the 34-day war in June and August 2006, which were found using search engines, media outlets, and blogs. Blogs had to be based in Lebanon or Israel, had to have at least five posts during the 34 days, had to be in English, had to have at least one hit in the global media, and had to be single- or group-authored rather than blog fora.

The final speaker in this first session at AoIR 2009 is Carol Soon, who shifts our focus to Singaporean political bloggers. Political blogging and related forms challenge conventional top-down communication flows, of course, and in doing so also undermines established entities' authority in information dissemination. What follows is a diversification of political participation in the networked public sphere - and in the Singaporean context, then, who are the key players here?

The networked public sphere can be seen as an autopoietic system,in which flows of communication and relationships are self-organising, move from the bottom up, freely within clusters and in a self-determined fashion. This challenges systems which traditionally hold more powerful positions - and hyperlink analysis can be utilised to examine the flows of information in this changing environment. Such flows may involve conventional political parties, but also civil society groups (which in Singapore particularly challenges the established system).

The third speaker in this session at ANZCA 2009 is Tim Highfield, who works on a comparative study of political blogs in Australia and France (and is one of my PhD students). He focusses here on the Australian side and its reaction to the inauguration of Barack Obama. The project tracks some 245 blogs and news Websites in Australia, and extracts from these each post (and its links) as they become available online. These data are then quantitatively analysed for keyword and link patterns.

The Obama inauguration was a major political event, of course, and provided a useful case study for this work; other such samples could be the swine flu epidemic or the 'utegate' controversy storm in a teacup. Interestingly, only about 50 blogs in the population published a post or more during the two weeks surrounding the inauguration (possibly due to the fact that January is a major holiday month in Australia). There was no major spike on inauguration day itself, either.
