Call for Papers: Workshop on Recommender Systems for Technology Enhanced Learning (RecSysTEL)

May 31st, 2010 by Martin

The first Workshop on Recommender Systems for Technology Enhanced Learning (RecSysTEL 2010) will be held on September 29 or 30, 2010, in conjunction with the 4th ACM Conference on Recommender Systems (RecSys 2010) and 5th European Conference on Technology Enhanced Learning (EC-TEL 2010) in Barcelona.

AIM & TOPICS

Technology enhanced learning (TEL) aims to design, develop and test socio-technical innovations that will support and enhance learning practices of both individuals and organisations. It is an application domain that generally addresses all types of technology research & development aiming to support of teaching and learning activities. Information retrieval is a pivotal activity in TEL, and the deployment of recommender systems has attracted increased interest during the past years.
Recommendation methods, techniques and systems open an interesting new approach to facilitate and support learning and teaching. There are plenty a resource available on the Web, both in terms of digital learning content and people resources (e.g. other learners, experts, tutors) that can be used to facilitate teaching and learning tasks. The challenge is to develop, deploy and evaluate systems that provide learners and teachers with meaningful guidance in order to help identify suitable learning resources from a potentially overwhelming variety of choices.
The aim of the Workshop is to bring together researchers and practitioners that are working on topics related to the design, development and testing of recommender systems in educational settings as well as present the current status of research in this area and create cross-disciplinary liaisons between the RecSys and EC-TEL communities. Overall, it aims to outline the rich potential of TEL as an application area for recommender systems, as well as expose participants to the challenges of developing such systems in a TEL context.

Topics include but are not limited to:

* User tasks to be supported by recommender systems in TEL
* Focus of recommendation in TEL
* Requirements for the deployment of TEL recommender systems
* Publicly available data sets for TEL recommender systems
* Recommendation algorithms and systems for TEL
* Transfer of successful algorithms and systems from other application areas
* Evaluation criteria and methods for TEL recommender systems

IMPORTANT DATES

20 June 2010: Submissions
16 July 2010: Notifications
1 August 2010: Camera-ready of accepted papers
29-30 September 2010: RecSysTEL Workshop in Barcelona

DATATEL CHALLENGE

Published datasets in recommender systems, such as the MovieLens and EachMovie ones, are very often used in experimental testing of new recommendation algorithms. Very few datasets are publicly made available online for TEL applications. Thus, it is not possible yet for TEL recommender systems’ researchers to apply and benchmark their algorithms on existing, public datasets.
To this end, the dataTEL Theme Team of the European STELLAR Network of Excellence (http://www.teleurope.eu/pg/groups/9405/datatel/)
is sponsoring the dataTEL Challenge: a call for TEL datasets that invites research groups to submit existing datasets from TEL applications that can be used as input for TEL recommender systems (e.g. ratings, tags, bookmarks).

The winner of the dataTEL Challenge will receive a best TEL dataset award.

Call for Papers: 3rd Workshop on Information Credibility on the Web

January 18th, 2009 by Martin

The 3rd Workshop on Information Credibility on the Web (WICOW 2009) will be held on April 20th or 21st, 2009, in conjunction with the 18th World Wide Web Conference in Madrid, Spain!

* WORKSHOP DESCRIPTION*

As computers and computer networks become more common, a huge amount of information, such as that found in Web documents, has been accumulated and circulated. Such information gives many people a framework for organizing their private and professional lives. However, in general, the quality control of Web content is insufficient due to low publishing barriers. In result there is a lot of mistaken or unreliable information on the Web that can have detrimental effects on users. This situation calls for technology that would facilitate judging the trustworthiness of content and the quality and accuracy of the information that users encounter on the Web. Such technology should be able to handle a wide range of tasks: extracting credible information related to a given topic, organizing this information, detecting its provenance, clarifying background, facts, and other related opinions and the distribution of them, and so on. The problem of Web information reliability and Web data quality has become also apparent in the view of the recent emergence of many popular Web 2.0 applications, the growth of the so-called Deep Web and the ubiquity of Internet advertising.

* TOPICS *

The aim of this workshop is to provide a forum for discussion on issues related to information credibility criteria and the process of its evaluation. We invite submissions on any aspect of information credibility on the Web. Topics include, but are not limited to:

  • Information credibility evaluation and its applications
  • Web content analysis for credibility evaluation
  • Author’s intent detection
  • Credibility of Web search results
  • Search models and applications for trustworthy content on the Web
  • Conflicting opinion detection
  • Online media and news credibility
  • Multimedia content credibility
  • Credibility evaluation of user-generated content (e.g., Wikipedia, question answering sites)
  • Information credibility evaluation in social networks and Web 2.0 applications
  • Analysis of information dissemination on the Web (e.g., in blogosphere)
  • Spatial and temporal aspects in information credibility on the Web
  • Information credibility theory and fundamentals
  • Estimation of information age, provenance and validity
  • Estimation of author’s and publisher’s reputation
  • Sociological and psychological aspects of information credibility estimation
  • Users study for information credibility evaluation

MACE at the Biennale in Venice

September 16th, 2008 by Martin

A long time ago since I blogged here the last time. A lot has happened - e.g., ALOE has become part of the European Project MACE (Metadata for Architectural Contents in Europe). Its aim is to create a common infrastructure for enriching and retrieving educational contents about architecture in Europe. In MACE, ALOE is used as a social layer - it allows users to tag, rate and comment on MACE resources, to create personal portfolios, and to contribute new resources.

Right now, MACE is presenting the mæve installation at the Venice Biennale. The aim is to connect the entries of the EveryVille student competition, and to put them into the larger context of MACE content and metadata. Visitors can place physical project cards on an interactive surface, exploring an organic network of projects, people and media.

I think it looks absolutely amazing - Kudos to the developers: the Interface Design team of the University of Applied Sciences Potsdam. Great job! I’m looking very much forward to see the installation live this weekend!

The best reviews I’ve ever seen

June 2nd, 2008 by Martin

Luckily, all the SPAM problems seem to have disappeared now (except for the SPAM that I’m creating myself here), and a new Wordpress version is now running. Time to share with you one of the funniest moments in the last weeks (where I’ve been to Edmonton at the Alberta University, but that’s a different story).

I was co-author of an extended abstract that a colleague of mine submitted some weeks ago. He submitted a .doc that was readable without any problems, even using Linux. It contained exactly as many characters as allowed. It was really simple stuff, nothing special. And here are the two reviews he got:

It is too short to judge and difficult to understand

your abstract is somehow a black box impossible to assess

I really LOVE these reviews. And maybe it was good not be accepted there…

I have the pleasure to be member of the program committee of the 2nd workshop 2nd on Social Information Retrieval for Technology-Enhanced Learning (SIRTEL).

Topics of interests are (amongst others) Technology Enhanced Learning (TEL) and Social Information Retrieval (SIR) techniques such as:

  • Recommender systems
  • Social collaborative searching, browsing and sharing of queries
  • Social network analysis
  • Game-theoretic approaches to select learning materials and learning partners in the long tail
  • Social bookmarking and tagging, folksonomies
  • Annotations, ratings and evaluations

You can contribute research papers, system demos, hands-on proposals and even “Pecha Kucha” talks. Sounds like some serious fun!

educamp ilmenau

April 19th, 2008 by Martin

I’m currently attending the educamp in Ilmenau. A lot of interesting sessions, especially yovisto really impressed me. If offers “academic video search” and already links to approximately 3000 videos, a lot of them from Germany, but also content from, e.g., MIT Lectures. What is really cool is the automatic indexing of videos using ocr, and the possibility to tag a certain point in time and to post these tags in other social bookmarking systems. Great work!

In the moment, I’m listening to a nice presentation about the digital profil of a fake identity (Rainer Buhl-Schied - good one). And of course I’ll attend the session with Stephan Downes, I hope they will set up a good connection…

re:publica 08

April 4th, 2008 by Martin

I’m currently in Berlin attending the re:publica. The current session is quite boring, so I used the time to upload the slides of the presentation I gave yesterday. It’s called “Sagt wer? Metadaten im Web”. Slides are in German, but not that much text anyway.

The presentation is about why metadata is important, how metadata can be generated, and about why we should embrace any kind of information that is available. At least when we have the choice what to use in which way. And of course I also talked about ALOE , also introducing our tag recommendation approach. More on this topic when I’m back from Berlin, and when the FP7 madness is over.
