CfP: Modeling Social Media

Markus Strohmaier has pointed out the following CfP to me: International Workshop on Modeling Social Media 2010 (MSM’10). It takes place June 13th, 2010, and is co-located with Hypertext 2010, Toronto, Canada. Submission deadline is April 9th, 2010 and topics are

• new modeling techniques and approaches for social media
• models of propagation and influence in twitter, blogs and social tagging systems
• models of expertise and trust in twitter, wikis, newsgroups, question and answering systems
• modeling of social phenomena and emergent social behavior
• agent-based models of social media
• models of emergent social media properties
• models of user motivation, intent and goals in social media
• cooperation and collaboration models
• software-engineering and requirements models for social media
• adapting and adaptive hypertext models for social media
• modeling social media users and their motivations and goals
• architectural and framework models
• user modeling and behavioural models
• modeling the evolution and dynamics of social media

More information can be found on the workshop home page.

Ever borrowed something and forgot about it?

I got a nice link some days ago. On qulpa.com one can register items borrowed or lent to remind friends of the debts or mange your own debts. That’s a nice and handy thing, especially for managing computer games Best of all, the company was founded by a friend of mine

Average Flickr uploads in the last minute …

I grabbed the number of photos uploaded in the last minute every 5 minutes from February 25th 2010, 1 pm to March 5th 2010, 2.30 pm (CET). This resulted in a number of 1,703 samples. This does not sum up to the actual time because timeouts and network problems occurred in between. Nevertheless I found:

• Average uploads per minute: 4,602
• Sample minimum and maximum: 1,852 and 8,849

This is interesting as many research papers (including some of my own) talk about upload rates of 6,000-8,000 photos per minute, which definitely does not reflect the average value. This might be a good reminder that systems actually working with people change and that we have to take a look at the number periodically.

ZoRa Photo Director

Just got word from Berthold Daum that he has integrated LIRe in the ZoRa Photo Director. That’s desktop asset management application, written in Java which allows for management of large photo collections. Source and binaries (Win & Linux) are available at http://www.photozora.org. Not to forget: it’s built on Eclipse!

CfP Workshop on Interoperable Social Multimedia Applications (WISMA 2010)

11th International Workshop of the Multimedia Metadata Community
http://dmag.ac.upc.edu/conferences/wisma2010/

• Submission due: 28th February 2010
• Workshop dates: 19th-20th May 2010
• Workshop venue: Universitat Politècnica de Catalunya, Barcelona (Spain)

In the Web 2.0, a growing amount of multimedia content is being shared on Social Networks. Due to the dynamic and ubiquitous nature of this content (and associated descriptors), new interesting challenges for indexing, access, and search and retrieval have arisen.
In addition, there is a growing concern on privacy protection, as a lot of personal data is being exchanged. Teenagers (and even younger kids), for example, require special protection applications; while adults are willing to have a higher control over the access to content.
Furthermore, the integration of mobile technologies with the Web 2.0 applications is also an interesting area of research that needs to be addressed; not only in terms of content protection, but also considering the implementation of new and enriched context-aware applications.
Finally, social multimedia is also expected to improve the performance of traditional multimedia information search and retrieval approaches by contributing to bridge the semantic gap. The integration of these aspects, however, is not trivial and has created a new interdisciplinary area of research.
In any case, there is a common issue that needs to be addressed in all the previously identified social multimedia applications: the interoperability and extensibility of their applications. Thus, the workshop is particularly interested in research contributions based on standards.

Recommended topics include, but are not limited to, the following:
•       Privacy in social networks
•       Access control in social networks
•       Social media analysis
•       Social media retrieval
•       Context-awareness in social networks
•       Mobile applications scenario
•       Social networks ontologies and interoperability
•       Security and privacy ontologies
•       Content distribution over social networks
•       Multimedia ontologies and interoperability
•       Multimedia search and retrieval
•       Semantic metadata management
•       Collaborative tagging
•       Interaction between access control and privacy policies
•       Social networks and policy languages
•       Policy management

Research Papers: Papers should describe original and significant work in the research and industrial practice of related topics. (i) Long papers: up to 8 pages, will normally be particularly focused on research studies, applications and experiments (ii) Short papers: up to 4 pages, will be particularly suitable for reporting work-in-progress, interim results, or as a position paper submission.

Applications and Industrial Presentations: Proposals for presentations of applications and tools, including reports on the application and utilisation of tools, industrial practices and models, or tool/system demonstrations. Abstract: 2 pages.

All submissions and proposals are to be in English and submitted in PDF format at the WISMA paper submission web site (http://www.easychair.org/conferences/?conf=wisma2010) on or before 28th February 2010. Papers should be formatted according to LNCS style (http://www.springer.com/computer/lncs?SGWID=0-164-7-72376-0). The workshop proceedings are to be published as a volume at CEUR Workshop Proceedings (http://ceur-ws.org).

Best Paper Award

“SPCD – SPATIAL COLOR DISTRIBUTION DESCRIPTOR – A Fuzzy Rule based Composite Descriptor Appropriate for Hand Drawn Color Sketches Retrieval” received the best paper award at the 2nd International Conference on Agents and Artificial Intelligence (ICAART), Valencia-Spain, January 22-24, 2010.

Congratulations to Savvas!

XBox360 Controller Buttons – Clipart

Lately I needed high resolution images of the XBox controller buttons for a simple game, but they where nowhere to be found. So I took my time and made images of the four most prominent ones. They are available in 800×800 pixels, free to use everywhere you want. The zip file contains 4 PNGs with transparent background. If you want to try yourself: basically I was following a tutorial, to be found here.

My Talk @ Florida Atlantic University

Just hours ago I finished my talk here at FAU, Boca Raton,FL, USA. I was talking about user intentions or what I call “the other end of the camera”. It was the first time I presented a whole overview on the “Intentions & Multimedia” thing I’m working on now for quite a long time, and I think it was very well recieved.

Visiting a 3D Cave – A Wrapup

On Nov. 27th I organized a trip to Graz, where the Institute for Computer Graphics and Visualization (CGV) of Graz University of Technology has a 3D cave installation called DAVE (Definitely Affordable Virtual Environment). 26 people and me took the bus to Graz and experienced a whole lot of interesting virtual environment effects. The cave itself gives a great insight on “what is possible” and we all were really amazed what can be done with proper equipment and – of course – a lot of work. Marcel Lancelle and Volker Settgast were excelleent hosts and explained the whole things and virtually left no questions unanswered. Check out the photos and the videos of the trip

SeMuDaTe 09 already started

I’m currently in Graz, chairing the first session of SeMuDaTe 09, a community workshop of the multimedia metadata community. I’m looking forward to a day full of interesting talks and discussions. Proceedings of the event are already available at ceur.ws. Our paper on Global vs. Local Feature in Video Summarization will be presented in the afternoon by my colleague Marian Kogler.
