A look back at Downscale2016

On 29 August, the 4th International Workshop on Downscaling the Semantic Web (Downscale2016) was held as a full-day workshop in Amsterdam co-located with the ICT4S conference. The workshop attracted 12 participants and we received 4 invited paper contributions, which were presented and discussed in the morning session (slides can be found below). These papers describe a issues regarding sustainability of ICT4D approaches, specific downscaled solutions for two ICT4D use cases and a system for distributed publishing and consuming of Linked Data.. The afternoon session was reserved for demonstrations and discussions. An introduction into the Kasadaka platform was followed by an in-depth howto on developing voice-based information services using Linked Data. The papers and the descriptions of the demos are gathered in a proceedings (published online at figshare: doi:10.6084/m9.figshare.3827052.v1).

During the discussions the issue of sustainability was addressed. Different dimensions of sustainability were discussed (technical, economical, social and environmental). The participants agreed that a holistic approach is needed for successful and sustainable ICT4D and that most of these dimensions were indeed present in the four presentations and the design of the Kasadaka platform. There remains a question on how different architectural solutions for services (centralized, decentralized, cloud services) relate to eachother in terms of sustainability and when a choice for one of these is most suited. Discussion then moved towards different technical opportunities for green power supplies, including solar panels.

The main presentations and slides are listed below::

  • Downscale2016  introduction (Victor and Anna) (slides)
  • Jari Ferguson and Kim Bosman. The Kasadaka Weather Forecast Service (slides)
  • Aske Robenhagen and Bart Aulbers. The Mali Milk Service – a voice based platform for enabling farmer networking and connections with buyers. (slides)
  • Anna Bon, Jaap Gordijn et al. A Structured Model-Based Approach To Preview Sustainability in ICT4D (slides)
  • Mihai Gramada and Christophe Gueret Low profile data sharing with the Entity Registry System (ERS) (slides)

A Mobile App for Sign Language Learning in Sub-Saharan Africa

[This post by Julia Salomons describes her Computer Science Master project]

‘Communication is key’ a phrase known worldwide, it is how people exchange ideas, knowledge, feelings, thoughts and much more.  Communication between people comes in all different forms: verbal, visual or electronic to name a few. For many choosing which form of communication they wish to communicate in is an option. However, when someone suffers from hearing loss they tend to lose the option to choose.

Depending where you are in the world, the support and care that is available to those who are deaf can vary greatly. In developing regions such as Sub-Saharan Africa (SSA) the support and care varies within the region, from acceptance to rejection. Where on one end of the spectrum, acceptance, individuals are allowed to express themselves how they want whereas on the other end individuals are trapped in their environment. Where some cases they fear for their lives.

The problem that was uncovered during our research showed us that there was a lack of communication between hearing and deaf individuals. Deaf individuals who were lucky enough to attend school or gain support from the government or organisations, learned how to communicate through sign language. However, even with the ability to communicate the communication with other deaf individuals is where the communication stops, which increases the gap between deaf and hearing individuals. This project focused on decreasing that gap, by creating an educational mobile application, Learn to Sign, which would assist hearing individuals learn sign language.
