SECOND CALL FOR TEL DATASETS

dataTEL Challenge on Sharing datasets for Technology-Enhanced Learning
Barcelona, Spain, 30 September 2010

Organised jointly by:
- dataTEL Theme Team of STELLAR Network of Excellence
- Joint Workshop on Recommender Systems for Technology-Enhanced Learning (RecSysTEL)
- 5th European Conference on Technology Enhanced Learning (EC-TEL 2010)

AIM & TOPICS

In the world of recommender systems, it is a common practice to use public available
datasets from different application environments (e.g. MovieLens, Book-Crossing, or EachMovie)
in order to evaluate recommendation algorithms. These datasets are used as benchmarks
to develop new recommendation algorithms and compare them to other algorithms in given settings.
In such datasets, a representation of implicit or explicit feedback from the users
regarding the candidate items is stored, in order to allow the recommender system
to produce a recommendation. This feedback can be in several forms.
For example, in the case of collaborative filtering systems it can be ratings or votes
(i.e. if an item has been viewed or bookmarked). In the case of content-based recommenders,
it can be product reviews or simple tags (keywords) that users provide for items.
Additional information is also required such a unique way to identify who provides
this feedback (user ID) and upon which item (item ID). The user-rating matrix used
in collaborative filtering systems is a well-known example.

Although recommender systems are increasingly applied in Technology Enhanced Learning (TEL),
it is still an application area that lacks such publicly available and interoperable datasets.
So although there is a lot of research conducted on recommender systems in TEL, they lack
datasets that would allow the experimental evaluation of the performance of different
recommendation algorithms using comparable, interoperable, and reusable datasets. This
leads to awkward experimentation and testing such as using datasets from movies in order
to evaluate educational recommendation algorithms.

To this end, the dataTEL Theme Team of the STELLAR Network of Excellence
(http://www.teleurope.eu/pg/groups/9405/datatel/) has launched the first
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.

A special dataTEL Cafe event will take place during the RecSysTEL Workshop 2010 in Barcelona,
to discuss about such issues and facilitate dataset sharing in this community. A best dataTEL
award will also be given to a TEL dataset that will be selected from a specially appointed
Scientific Committee.

IMPORTANT DATES

* 1 July 2010: Submissions
* 16 July 2010: Notifications
* 1 August 2010: Camera-ready
* 30 September 2010: dataTEL Cafe event during RecSysTEL workshop and before the ECTEL conference dinner

SUBMISSIONS

The dataTEL Challenge submissions should include:
* TEL dataset file(s): preferably in CSV or XML format
* TEL dataset description: 2 pages formatted according to Springer LNCS
(http://www.springer.com/computer/lncs?SGWID=0-164-6-793341-0)

The dataset files(s) should be made available through some URL (e.g. FTP location).
The 2-page description should be submitted through the EasyChair submission system:
http://www.easychair.org/conferences/?conf=datatel2010

If you haven't an EasyChair account yet, you'll be asked to create it before you can access the dataTEL page.

For more information on content and formatting of the dataset and the 2-page description, see:

ABOUT RecSysTEL AND EC-TEL 2010

The RecSysTEL Workshop aims 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. 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.
See http://adenu.ia.uned.es/workshops/recsystel2010/.

The 5th European Conference on Technology Enhanced Learning (EC-TEL 2010)
brings together technological developments, learning models, and implementations
of new and innovative approaches to training and education. The conference
traditionally explores how the synergy of multiple disciplines
can provide new, more effective and more especially more sustainable,
technology-enhanced learning solutions to learning problems.
