Weekend Post on Team Fortress 2: Meet the Spy

The TF2 team has prepared another great video on the gameplay characters. Now the spy is the one every looks (or tries to look) at 🙂

You’ve met the Scout, the Soldier, the Demoman, the Heavy, the Engineer, and the Sniper. Then, for some reason, a sandwich. But now it’s time to meet the stealthiest, shiftiest, most secretive, suit-wearing TF team member of all…


That’s right, it’s finally time to Meet the Suit-Wearing Secret Sandwich!

No, it’s Meet the Spy.

Contribution @ I-KNOW 09 accepted!

The contribution of Christoph Kofler and me with the title “An exploratory study on the explicitness of user intentions in digital photo retrieval” has been accepted for publication and presentation at the I-Know ’09. Here is the abstract (the full paper will follow as soon as we have prepared the camera ready version):

Search queries are typically interpreted as specification of information need of a user. Typically the search query is either interpreted as is or based on the context of a user, being for instance a user profile, his/her previously undertaken searches or any other background information. The actual intent of the user – the goal s/he wants to achieve with information retrieval – is an important part of a user’s context. In this paper we present the results of an exploratory study on the interplay between the goals of users and their search behavior in multimedia retrieval.

This work has been supported by the SOMA project.


Self Organizing Multimedia Architecture (SOMA) – The Project

Currently we are working a lot on a research project funded by a Carinthian agency. The project goes on for 3 years (2.5 years left) and has enough funds to pay 4 PhDs and 1 post doc researcher. Here is the description and the link to the blog:

The project Self-organizing Multimedia Architecture (SOMA) aims to capture the whole life-cycle of multimedia content in a single architecture for large distributed multimedia information systems. In SOMA we focus on scenarios where events, which we understand as “limited time periods of special importance”, are a central concept. Examples for such scenarios are sports events stretching over time, where start, finish or critical parts of a race are possible events, or traffic monitoring, where events like traffic jams or accidents have to be reported and investigated.

ACM SIGMM 1st International Workshop on Social Media (WSM2009)

in conjunction with ACM Multimedia 2009, Oct. 19-24, 2009, Beijing, P.R. China

Important dates:

Submission deadline – 5 July, 2009
Notification date – 17 July, 2009
Camera ready date – 24 July, 2009
Workshop date – 23 October, 2009


Recent years have witnessed a growing number of user-centric multimedia applications, especially with the popularity of web 2.0. Examples include Flickr, YouTube, Facebook, MySpace, Orkut,, etc. The emerging applications on social web and social networks have produced a new type of multimedia content, termed as “social media” here as it is created by people using highly accessible and scalable publishing technologies for sharing via the web. With social media, web images, videos and audios are generally accompanied by rich contextual information, such as, tag, category, title, metadata, comments, and viewer ratings, etc. Massive emerging social media data offer new opportunities for resolving the long-standing challenges in multimedia understanding, e.g., the semantic gap issue. This new media also introduces many challenging and new research problems and as well as many exciting real-world applications (e.g. social image search, social group recommendation, etc.). This workshop solicits novel contributions on various aspects of social media research. Workshop papers will elaborate related theory, methodology, algorithms and issues associated to social media content creation, manipulation, content analysis, storage, search, learning, and mining.

Micro Loans with Kiva

Yesterday Markus Strohmaier pointed me towards Kiva, a microloan page. I think this is a great way to help people!

Choose an Entrepreneur, Lend, Get Repaid

The below diagram shows briefly how money gets from you to an entrepreneur, and back.

1) Lenders like you browse profiles of entrepreneurs in need, and choose someone to lend to. When they lend, using PayPal or their credit cards, Kiva collects the funds and then passes them along to one of our microfinance partners worldwide.

2) Kiva’s microfinance partners distribute the loan funds to the selected entrepreneur. Often, our partners also provide training and other assistance to maximize the entrepreneur’s chances of success.

3) Over time, the entrepreneur repays their loan. Repayment and other updates are posted on Kiva and emailed to lenders who wish to receive them.

4) When lenders get their money back, they can re-lend to someone else in need, donate their funds to Kiva (to cover operational expenses), or withdraw their funds.

Presentation on “Visual Information Retrieval”

Tomorrow I’m an invited speaker at Graz University of Technology in the course on “Applications of Knowledge Management” of Markus Strohmaier. I’ll talk about Visual Information Retrieval featuring the Semantic Gap and a round-up of low level features and indexing strategies. Looking forward to this event as I really like these overview presentations 😀
