| WWW 2005 2nd Annual Workshop on the Weblogging Ecosystem: Aggregation, Analysis and Dynamics
Chiba, Japan, May 10th 2005
Theme of the Workshop
The weblogging microcosm has evolved into a distinct form, into a
community of publishers. The strong sense of community amongst
bloggers distinguishes weblogs from the various forms of online
publications such as online journals, 'zines and newsletters that
flourished in the early days of the web and from traditional media
such as newspapers, magazines and television. The use of weblogs
primarily for publishing, as opposed to discussion, differentiates
blogs from other online community forums, such as Usenet newsgroups
and message boards. Often referred to as the blogsphere, the network
of bloggers is a thriving ecosystem, with its own internally driven
dynamics.
The cross-linking that takes place between blogs, through blogrolls,
explicit linking, trackbacks, and referrals creates implicit and
explicit networks which define the communities of the weblogging
world. create a strong sense of community in the weblogging
world. There is work underway to understand the dynamics of the
weblogging network, much of which springs from bloggers
themselves. The self-publishing aspect of weblogs, the time-stamped
entries, the highly interlinked nature of the blogging community and
the significant impact of weblog content on politics, ideas, and
culture make them a fascinating subject of study.

Invited Talk: Media Attention in the Age of the Weblog - Will Blogs Make News More or Less Global?, Ethan Zuckerman
Abstract: Weblogs are revolutionizing journalism, allowing a new group of amateur citizen journalists to complement and challenge professional journalists. How are news stories flowing from mainstream media into weblogs, and vice versa? Is there a pattern to what stories bloggers "amplify" from mainstream media? Will weblogs be able to help journalism conquer one of its most persistent problems - a failure to report news from the developing world? Or will the demographic biases of webloggers help reinforce mass media's tendencies to report on wealthy nations? My talk explores these questions (and the history behind them), presents ongoing research and explores new strategies for investigating these questions.

Extracting Latent Weblog Communities: A Partitioning Algorithm for Bipartite Graphs, Kazunari Ishida, Tokyo University of Agriculture
Abstract: I propose the concept of a latent weblog community (LBC), as a means to promote the automomous organizaiton of knowledge on the Internet. Such communities can be illustrated in terms of bipartite graphs based on weblog update information, and they can effectively function to create meeting spaces for bloggers who write about similar or closely related topics but do not know each other. To extract these communities from blogspace, I developed a partioning algorithm known as the Weakest Pair (WP) algorithm, which separates the weakest pairs of bloggers and webpages, respectively, using co-citation information.

Discovering Important Bloggers Based on a Blog Thread Analysis, Shinsuke Nakajima, NICT
Abstract: To capture "hot" conversation topics from blogs and deliver them to users in a timely manner, we propose a method of discovering bloggers who take an important role in conversations. We characterize bloggers based on their roles in previous blog threads (a set of blog entries comprises a conversation). We discuss models of blogs and blog thread data, and methods of extracting blog threads, discovering important bloggers, and acquiring important content from their entries.

The EigenRumor Algorithm for Ranking Blogs, Ko Fujimura, NTT Corporation
Abstract: This paper proposes a new algorithm called "EigenRumor" that scores each blog entry based on eigenvector calculations. This algorithm enables a higher score to be assigne to the blog entries submitted by a good blogger but not yet linked to by any other blogs based on acceptance of the blogger's prior work.

Tomographic Clustering To Visualize Blog Communities as Mountain Views, Belle Tseng, NEC
Abstract: In our paper, we combine blog rankings with their social connections to provide a framework to understand multiple blog communities. A novel mountain view visualization is provided to explore different communities of interest in blogspace. The mountain views are generated using a tomographic clustering algorithm on the blog social network.

The Political Blogosphere and the 2004 U.S. Election: Divided They Blog, Natalie Glance, Nielsen BuzzMetrics and BlogPulse
Abstract: In this paper, we study the linking patterns and discussion topics
of political bloggers. Our aim is to measure the degree of
interaction between liberal and conservative blogs, and to uncover
any differences in the structure of the two communities.
Most significantly, we find differences
in the behavior of liberal and conservative blogs, with
conservative blogs linking to each other more frequently and in a
denser pattern.

GIS and the Blogosphere, Matt Hurst, Nielsen BuzzMetrics and BlogPulse
Abstract: This paper describes some baseline experiments in relating bloggers to geographical locations. It describes an application of simple Geographical Information Systems methods to the results of a naive location identifying technology, drawing some interesting insights about the distribution of bloggers.

Analyzing concerns of people using Weblog articles and real world temporal data, Tomohiro Fukuhara, RISTEX
Abstract: We describe an apprach and some preliminary results of concern analysis using Weblog and real world temporal data. By analyzing Weblog articles, we can find temporal changes of concerns of people.

Learning Contextualised Weblog Topics, Paolo Avesani, I.R.S.T.
Abstract: In this paper, we examine how a topic-centric view of the Blogosphere can be created. We characterise the problems in aligning similar concepts created by a set of distributed, autonomous users and describe current iniatives to solve the problem. We introduce the Tagsocratic project, a novel initiave to solve the concept alignment problem using techniques derived from research in language acquisition among distributed, autonomous agents.

Blogging, RSS and the Information Landscape: A Look at Online News, Kathy Gill, University of Washington
Abstract: This paper explores the effect that blogs have had on the adoption of RSS syndication by online news web sites. It uses the diffisuion of innovation models presented in Everett Rogers' The Diffusion of Innovation and Brian Winston's Media, Technology and Society to explain the relationship between RSS, blogs, and online news.

Differences between Blogs and Web Diaries, Toshiaki Fujiki, Tokyo Institute of Technology
Abstract: There had been many "web diaries" before the blogs arrived in Japan. In this paper, we discuss whether the differences between blogs and "web diaries" are significant for text mining or not. We conducted experiments to find the differences by comparing hot topic words automatically extracted from blogs and web diaries. The results suggested that we could obtain better results by using blogs and web diaries together rather than by only using the RSS data of blogs.
