Do you have an interest in analyzing Big Data, collected in real life, mobile context? Nokia Research Center Lausanne and its academic Swiss partners have recently completed a Data Collection Campaign in the Lake Geneva region. Data from smartphones of almost 200 participants was collected in the course of 1+ year.

The Mobile Data Challenge (MDC) releases the Lausanne data for the research community. The challenge provides you an opportunity to analyze a comprehensive and relatively unexplored data set including rich social and geographic information. Selected entries will be invited to participate in a workshop organized in conjunction with the Pervasive 2012 conference.

· The final workshop of the MDC has been now announced also on the Pervasive 2012 web page: http://pervasiveconference.org/2012/workshops.php

Description of the MDC:

The MDC comprises two alternative tracks: Open Track and Dedicated Track. In the Open Track, you are given the opportunity to approach the data set from an exploratory perspective. You can propose your own Challenge task, which matches with your own research interests and background. You can e.g. discover hidden behavioural patterns through statistical techniques, focus on more methodological contributions related to data mining or develop novel ways for data visualization.

The Dedicated Track gives you the possibility to take on up to three alternative concrete tasks to solve, with properly defined training and test sets, and evaluation measures that will be used to assess and rank all the contributions. The tasks are related to prediction of the semantic labels of the places, next destinations of the users and demographic attributes from the mobile data.

For all cases, the description of your methods and/ or the findings of your analysis will be shared in the challenge in the form of a short paper, as well as any relevant accompanying material that you wish to share with the research community - such as analytics or visualization tools.

 

MDC schedule:

  • November 2011: Launch of the Call for the Challenge
  • December 7th 2011: Registration deadline for participation
  • Week1, 2012 (at the latest): Data is released

Evaluation and awards:

The open challenge entries will be evaluated according to the standard scientific criteria, including novelty, quality of contribution/documentation, etc., based on the feedback from the program committee of the MDC workshop. The dedicated tracks will be evaluated in comparison to ground truth data.

The best challenge entries in both tracks will be awarded prizes.

Open track:

1st prize: 3000€, 2nd prize: 2000€, 3rd prize: 1000€.

Dedicated track:

The rewarding budget of 6000 € will be distributed as cash prizes between best contributions of the different tasks of the dedicated track. The organizers reserve the right to distribute this sum unequally between the tasks of the dedicated track.

Additionally, prizes may include Nokia products.
