Aussois, France 1st- 6th September

The only use of an obstacle is to be overcome. All that an obstacle does with brave women and men is, not to frighten them, but to challenge them.
Woodrow Wilson





EDBT attendees will have room for expressing their creativity by participating in a research challenge. Speakers will propose challenges on their topics and students can work individually or in group for addressing such challenges.

challenge : “a test of one’s abilities or resources in a demanding but stimulating undertaking”, The free English dictionary 


  • — Polyglot meets Xperanto here
  • — Social networks  here
    • — Information spread and influence 
    • — Data mining and analysis
  • — Data repair with Map -reduce, here

The objective is to get together and have fun with the challenges U feel excited about. It is also a way of interacting with lecturers and sharing your ideas with them.


We had eleven groups addressing challenges:

  • — Two groups addressed Polyglot meets Xperanto
  • — Four groups addressed Social Networks challenges
  • — Five groups addressed Data repair with Map-Reduce

Proposals were presented during a Demo Fest. Each group was  evaluated by 2 referees with respect to five criteria: understanding of the problem, reach and soundness of the solution, and creativity/originality of the proposal.

We had very interesting proposals and all groups worked hard during the week. We are sure that with some weeks good effort, the proposals can lead to papers.

Referees deliberated and after very difficult decision making, two works were identified as the best proposals:

1st place: Social Networks

  • — Cigdem Aslay, University Pompeu Fabra & Yahoo! Research, Barcelona
  • — Behrooz Omidvar Tehrani, University of Grenoble
  • — Nafiseh Shabib, Norwegian University of Science and Technology

2nd place: Data cleaning with Map-Reduce

  • — Vadim Ivanov, UNL FCT
  • — Yaron Gonen, Ben-Gurion University of the Negev
  • — Noor Aldeen Alawad, Sapienza Univeristy of Rome
