Towards an Emerging CS Student Community for Regreening Africa: Random Impressions of our First Workshop

April 22, 2012

Two years after the kick off (reported here), we are gaining a lot of momentum with the Regreening Africa initiative.

Last Friday, 20 April, we organized a first mini workshop with master students who are conducting their master thesis project in the context of a Web for Regreening Africa. The Web Alliance for Regreening Africa initiative is primarily  funded by two running EC-funded research projects W4RA and m-Voices. However, regarding the societal relevance we are convinced we can deliver a convincing bargain for  a larger community of interest to emerge. We have many communities in mind; this workshop aimed at a community at VU of master/PhD students branching their research out from the central theme, but we also have established social networks such as Diaspora and ITGlobal in mind from which we aim to source content contributions.

Our main goal, hence bargain, is to establish a Web of African content through several microprojects. A selection:

  • crowdsourcing app for converting pluvial observation data in the Sahel;
  • crowdsourcing app for gathering voice fragments in different languages that can be used for voice-based services
  • a sustainability analysis for voice-based event organizer;
  • RadioMarché: distributed market information system for non-timber tree forest products;
  • linked data mash ups for NGOs.

This workshop was a first step in bringing VU Computer Science students’ projects together from Ghana, Ethiopia, Buthan, Iran, Netherlands, Zimbabwe, Suriname, etc. For an overview of the different lines we are exploring check our CAiSE 2012 position paper and ESWC 2012 poster and paper (to be published soon, see list below). Next, some impression from the projects. From my point of view, the meeting was a succes and we agreed to organize a second installment later this year.

Master students from around the Globe: The Netherlands, Iran, Buthan, Zimbabwe / South Africa, and Ethiopia.

In order to realise voice-based services for various dialects present in the Sahel, Roksareh Nakhaei builds an app that sources a crowd to produce voice fragments. The tasks here require specific language skills, so we cannot source from any general social network such as Facebook.

A mobile event organiser is one of the case studies identified in the m-Voices project. Through voice-based interfaces (using radio or phone) events can be published and consumed. The goal of this project, done by Albert Chifura is to analyse the cost of setting up such infrastructure, hence involvin a "business" sustainability model analysis.
