DATA FOR DEVELOPMENT: THE D4D ORANGE CHALLENGE ON MOBILE PHONE DATA

Overview:
The Orange "Data for Development" (D4D) challenge is an open data challenge on anonymous call patterns of Orange's mobile phone users in Ivory Coast. The goal of the challenge is to help address society development questions in novel ways by contributing to the socio-economic development and well-being of the Ivory Coast population. The website

http://www.d4d.orange.com

contains more information about the challenge as well as a description of the participation rules. The purpose of the attached paper is to describe the four datasets released for the challenge. The datasets are based on anonymized Call Detail Records (CDR) of phone calls and SMS exchanges between five million of Orange's customers in Ivory Coast between December 1, 2011 and April 28, 2012.

 
Datasets:
(1) antenna-to-antenna traffic on an hourly basis;
(2) individual trajectories for 50,000 customers for two week time windows with antenna location information;
(3) individual trajectories for 50,000 customers over the entire observation period with sub-prefecture
location information; and
(4) a sample of communication ego-graphs for 5,000 customers.
 
Guidelines:
(1) Review the attached paper D4D-v7.pdf and pay special attention to how to interpret the datasets.
(2) Review the cited attached papers.
(3) Access samples of datasets 1 to 4. Further instructions to be provided.
(4) Categorize the data so that you can create rules.
(5) Apply the apriori algorithm to find the strongest rules in the data.
 
Optional:
You can choose to submit your final project for the challenge by January 31, 2013. Submissions should take the form of a paper submission (as for a conference submission) with clear indications of authors and affiliations. There are no length limitations although the review committee typically expects submissions to be between 2 and 20 pages.
 
There are four money prizes (with $3,000 for the best entry). In addition to that, winning teams will be invited, expenses paid, to present their work at the NetMob conference in May 2-3, 2013 at MIT (Cambridge, USA).  Please talk to me if you are interested in entering the challenge.
