CfP: INFORMATIK 2010 Workshop on “Web Science”

CALL FOR PAPERS

INFORMATIK 2010 Workshop on “Web Science”

co-located with GI-Jahrestagung 2010 (http://www.informatik2010.de/)

Web science is often referred to as the “science of decentralized information systems”. While novel technologies such as semantic web, web services, and cloud computing are germane to the broad proliferation of Web technologies, we also need to understand phenomena of the Web in the small as well as in the large, in order to retain its usefulness and benefit to people. This is in the center of attention of Web science and includes besides the mentioned technological approaches, research related to online communities, information diffusion on the Web, Web governance, global network structures beyond the individual communities on the Web, growth analysis, incentive and monetization systems.

Because the web itself is socially embedded a particular focus of this first GI workshop on Web Science are social computing applications, such as Wikipedia, Facebook, or del.icio.us, which are analysed with regard to the complex interdependencies between constraints imposed by the technical system as well as with regard to their use in social actions and interactions under varying social contexts. Understanding dynamics and evolution of these systems, as they depend on inherent social and informational structures, is of particular interest, because it is the dynamics of such communities that determines their final success or failure. In order to analyze social computing applications, interplay between aspects of computer science, for example computational network analysis, visualization techniques, graph theoretic models, semantic web technologies, and machine learning techniques, with social science and psychology is required.

In this interdisciplinary workshop we are aiming to bridge the gap between paradigms and encourage interdisciplinary collaborations as well as advance and deepen our understanding of web science. Joint efforts are needed to take advantage of the state-of-the-art research from multiple disciplines, such as computer science, information systems, sociology, and psychology. Moreover, this workshop provides a platform for researchers and practitioners to exchange preliminary results, new concepts and methodologies in this area.

Geospatial visualization of origin of NYTimes readers

Ho ho ho!

It seems I was a bit busy the last weeks and this is very true. Today is the day to dissolve a little bit of the chaos on my computer and to be honest, I won’t have any chance, I just try to reduce the email overflow.

However, I’d like to share a very nice visualization of the The Times’s research and development labs. Nick Bilton refers in his article „A Day in the Life of NYTimes.com“ to two visualizations:

The first video shows readers of the NYTimes within the United States on one day, the day Michael Jackson died and the second the readers on a global base. Yellow circles and their sizes present the number of users who read the main NYTimes website from their desktop computer or laptop while the number and size of pink circles is according to the number of mobile application users. The position of the circles indicates the geographical origin.

Just watching these maps glow can be a mesmerizing experience, but there’s another fascinating piece of data within this particular day. At about 1 minute and 10 seconds into the video, at 5:20 p.m., you can see a huge pulse of readers coming to the Web site, both from mobile devices and personal computers. This huge traffic bump happened after TMZ.com broke the news of Mr. Jackson’s death. As the news started to filter across the Internet, traffic continued to ebb and flow throughout the evening.

Lecture on usability and free/open source software development

Last Wednesday (11/18/2009) I gave my first lecture at Carnegie Mellon University. The event itself was exciting enough but on top of that I got talk about my practical experiences with SONIVIS. In the beginning I wasn’t sure if this topic was interesting enough for my audience but in the end it was. We had really good and interesting discussions.

Let me first draw out my major thoughts. Based on a literature study, I could identify three main pitfalls by applying usability to free/open source software projects:

(1) Usability feedback is hard,
(2) HCI know-how is rare, and
(3) Usability is difficult to measure.

The first issue is mainly related to existing bug tracking systems. It is amazing how software-code-centered these applications still are. It is often only possible to post a textual description of your problem as uploading screenshots is complicated. Within free software projects BugZilla is mostly used. In 2008 CMU HCII Master students carried out an interesting study about user interface. However, there are commercial applications available that offer interesting functions as well. For example, JIRA allows you to integrate per drag-and-drop screenshots in your bug description. Addionally, JIRA offers many more nice features and it is free for use by official non-profit organizations. I know that contradicts the free software idea; however, it may be a feature for BugZilla. ☺

“HCI know-how is rare”. A good question is how more HCI specialists can be integrated into open source software projects. The KDE project is a very good example of doing this without any company support. Unfortunately, this project faces some challenges as well, as presented during the aKademia 2008 by Celeste Lyn Paul: http://blip.tv/file/1234620

The last issue, “usability is difficult to measure”, isn’t that specific for free/open source software projects. It is more of a general problem, but because of the distributed community in FOSS, it is even harder. However, solutions such as ingimp are promising. Ingimp is a tool that extends GNU Image Manipulation Program in order to collect real-time usability data. At least we have the data, but then we still need somebody who understands what the data mean.

However, in the last part of my lecture I presented some recent results of our efforts in SONIVIS to develop a more usable tool. Bringing usability to SONIVIS is still a very long way away…

New video campaign of the Free Software Foundation

It is a very good idea for the Free Software Foundation to ask free software users for short video-clips (2-5 minutes) about the question “why free software is important in everyday life”. In my point of view this new campaign will provide a better understanding of why people use free software and why it has a high impact on society. It is a lot about freedom…

Actually, Dana Moser has already started this initiative by asking people this question at the Women in Free Software Summit and at the Boston celebration of Software Freedom Day 2009. Results can be seen here

But here the main question: “Why do you love free software?”

Submission guidelines are here available.

CfP: New Review of Hypermedia and Multimedia

Call for Papers: New Review of Hypermedia and Multimedia

Special Issue on: Hypertext and Web Science: Emergent Structures, Communities and Collective Intelligence

Submission deadline: 4 January 2010

Hypertext has always been about people and their relationships with information. The Hypertext Community has over thirty years of experience of exploring hypertext interfaces, infrastructures and usage. Now Web 2.0 technology and practice has greatly promoted this sort of interactive collaboration and social networking, resulting in large scale collaborative knowledge creation and e-democracy activities. Semantic Web technologies and the Linked Data Web could impact even more strongly. Imagine if most personal and organisational data were available on the Web and analysable with the help of software agents, how would people and organisations run their businesses, how would theyidentify, select, and collaborate with their partners and customers to
face shared challenges?

NETWORK SCIENCE WORKSHOP: Videos now available

If you hadn’t the opportunity to attend the CMU Network Science Workshop in October, please have a look to the videos that are now here available. The objective of this workshop was to bring together scientists across the various disciplines who are dealing with networks in their research in order to generate new approaches for interdisciplinary research in this area. Just to mention some of them: David Krackhardt from Organizational Science, Kathleen Carley from Computer Science, Eric Xing from Machine Learning, and Stephen Fienberg from Statistics.

However, I attended this workshop and was very pleased by the idea of bringing together various disciplines. It was amazing to see how differently researcher work on this topic but at the same time how often they have the same challenges. It was definitely a good underlying idea but at the end there was to less space for discussions. But a good step in the right direction….

CfP: Visualization for Understanding CSCW Data (CSCW 2010 Workshop)

Visualization for Understanding CSCW Data (CSCW 2010 Workshop)

CSCW systems can be very complex to understand and analyze. Users click in various places, talk to each other, and collaboratively travel through websites. Their work in these places can often be best understood through data visualization: laying out the data visually can make sense of a great deal of data. This workshop expands on ideas from past workshops that have touched on visualization as a way of understanding data, including the CSCW 2004 Workshop on Social Networks.

- *November 20, 2009* – Position papers due; submissions will be acknowledged by email
