Structure of public expression online

Greetings from the Australian Demographic & Social Research Institute (ADSRI) at the Australian National Unviersity, where Hai Liang, Web Mining Lab, Department of Media & Communication, City University of Hong Kong s talking on "The structure of public expression and issue rise: Participation heterogeneity, concentration, and timing in internet forums". He studied 3,000 posts to Internet forums to find the the structure of the interaction. These were collected from a popular Chinese Internet forum. The results that threads of discussion which start intensively are more successful. The aim of this work was to contribute to civil society. It would be interesting to see if there are different forms of discussion in different countries, cultures and from people with different education.
The rise of public issues in Internet forums plays an important role in the formation of public opinion. This study investigates the structure of public expressions in the Internet forums, and aims to detect the structural characteristics of the successful rise of public
issues. This study analyzed 110 threads with more than 3,000 posts that were collected from a famous Chinese Internet forum. The results suggest participation heterogeneity, concentration, and intensive replies at the early stage are associated with a higher
probability of successful thread building. The model can explain 68.5% variance of the number of posts in the thread. The results imply that the structure of public expression is crucial for the rise of public issues. ...

Cowpaths in Hyperspace

Greetings from the Australian Demographic & Social Research Institute (ADSRI) at the Australian National Unviersity, where Lingfei Wu, from the Web Mining Lab,City University of Hong Kong is talking on "How the Web1.0 fails: The mismatch between hyperlinks and user-flow". He argues that rather than following the hyperlinks built into web sites, people follow other paths to data. He carried out an analsysi of these bottom up "clickstreams" in the top 918 websites in the world. He found the clickstreams to be highly clustered.

In landscape architecture a well known technique for working out where paths should be is to to wait for some use and then see where the ground is worn away by foot traffic. These are known as desire paths, or more colloquially "cow paths".

However, there does not seem to me any surprise in the fact that people do not follow the hypertext links on web sites. These links are placed for the convenience of the organisation preparing the information. Just as the books in a library are arranged for the convenience of librarians, not borrowers, the pages in a web site are primarily for the convenience of the organisation providing the web site, not the users.

An issue one of the deliagtes asked was about links from Twitter and Facebook. It was not clear if the analysis software used could capture this data.
The mismatches between ‘top-down’ systems and ‘bottom-up’ patterns exist widely in human society. People bothered by the problem include Walter Burley Griffin, M. S. Gorbachev, and Tim Berners-Lee. In this presentation, I shall show the mismatch between ‘top-down’ system (hyperlink web composed of the top 1000 websites in the world) and ‘bottom-up’ patterns (user-flow on the hyperlink web) in the virtual world. Moreover, I shall discuss how the ‘survival of the fittest’ in the virtual world leads to the evolution of the WWW from web 1.0 to web 2.0.
