VU’s 4th ICT4D symposium: a look back

Yesterday, 18 May 2017, the 4th International ICT4D symposium was held at Vrije Universiteit Amsterdam.  The event was organized by the W4RA team and supported by VU Network Institute, the Netherlands Research School for Information and Knowledge Systems SIKS, VU Computer Science Department and VU International Office. Invited speakers from Ghana, France and the Netherlands highlighted this year’s theme was “Sustainability and ICT4D”.

Keynote speaker Gayo Diallo from Universite de Bordeaux discussed the possibilities of ICT for African Traditional Medicine (ATM). In his talk, he showed how semantic web technologies can play a role here to connect heterogeneous datasets for analytics and end-user services. Such services would need to be based on voice-interaction and localized technologies. His slides can be found here.

Chris van Aart from 2Coolmonkeys discussed a number of smartphone applications developed in the context of W4RA activities, including Mr. Jiri a tree-counting application. He proved there is a market for such applications in the African context (Slides).

After the break, Francis Dittoh from UDS Ghana discussed issues around sustainbility for a meteo application he is currently developing for Northern-Ghana (slides). Wendelien Tuijp from VU’s CIS then presented multiple perspectives on ICT4D (Slides). The symposium was closed by a video presentation from Aske Robenhagen, showcasing the ongoing work in Nepal around mapping knowledge networks and developing a smartphone application supporting information exchange for local accountability extension workers. More information on that project can be found at nepalnetworks.org/

W4RA research displayed in Museon

In modern day research, dissemination is key and it is therefore always nice to see research results being shared with the public in new and unforseen ways. Our work within the Web for Regreening in Africa (W4RA) is now part of a exhibition in the Museon museum in the Hague. The exhibition focuses on the United Nations’ 17 Sustainable Development Goals (SDGs) for 2030. As content partner of the Museon, the W4RA programme of VU has contributed ideas, visuals and texts for the exposition related to SDG No. 15, entitled “Plant in het Zand” (Plant in the sand).museon exhibition images

From the press release: Land degradation and desertification are increasing due to both natural and human causes, including climate change and population pressures. Areas can no longer meet the needs of their populations, with famine and poverty as a result. There are various solutions, but regreening – the natural (re)generation and protection of trees by local farmers themselves – is a highly successful one. Belts of trees act as windbreaks, helping to stop soil blowing away, keeping it moist for longer, and providing a micro-climate that is better for people, animals and plants. Trees also provide food and many other economically useful products.

Within the W4RA programme, we integrate local ICT web and mobile app innovations to support local knowledge sharing around regreening efforts.

VU looking further in Mali

[This post by Anna Bon is cross-posted from W4RA.org. See also the VU press release: VU looking further in Mali]

On 13 October 2016, the W4RA team organized and co-chaired, a Green Climate Funds workshop together with Malian farmer organization AOPP (l’Association des Organisations professionnelles paysannes). The objective of the meeting was to form a consortium and prepare a project plan, which will be submitted in the framework of this United Nations program.

The workshop was attended by representatives from the Dutch Embassy, the Swedish and Norwegian embassies, and by development (donor) agencies from the EU, Germany, the United Nations Capital Development Fund, the Global Environment Facility (GEF) and a range of Malian and Dutch development organizations.

Mali is one of the poorest countries in the world, plagued by the effects of climate change and a civil war in the northern regions. The effects of land degradation and desertification are a serious threat to the food security of millions of people, especially those living in rural regions.

Recently, the United Nations prioritized its support to Mali in the framework of the Green Climate Funds, a new programme to fight the effects of climate change on global scale. In response to a call for proposals, organizations in Mali are forming consortia, to prepare project proposals for funding by the Green Climate Funds.

Through ongoing interdisciplinary research collaboration, W4RA has obtained extensive experience in socio-technical field-based action research in West Africa. Building on partnerships with local partners (AOPP, Sahel Eco and Radio Rurale – Mali, Réseau MARP -Burkina Faso, University for Development Studies – Ghana) VU’s research programme W4RA wants to contribute to regreening, local knowledge sharing, local innovation and emerging rural agro-forestry value chains.

Meanwhile the W4RA is training students, through community service education, in rural Africa. This is done through the ICT4D master course (artificial intelligence, information science, computer science,) and various master research projects (Network Institute Academy assistants, various master research projects).

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.

Msc project: Low-Bandwith Semantic Web

[This post is based on the Information Sciences MSc. thesis by Onno Valkering]

To make widespread knowledge sharing possible in rural areas in developing countries, the notion of the Web has to be downscaled based on the specific low-resource infrastructure in place. In this paper, we introduce SPARQL over SMS, a solution for exchanging RDF data in which HTTP is substituted by SMS to enable Web-like exchange of data over cellular networks.

SPARQL in an SMS architecture
SPARQL over SMS architecture

The solution uses converters that take outgoing SPARQL queries sent over HTTP and convert them into SMS messages sent to phone numbers (see architecture image). On the receiver-side, the messages are converted back to standard SPARQL requests.

The converters use various data compression strategies to ensure optimal use of the SMS bandwidth. These include both zip-based compression and the removal of redundant data through the use of common background vocabularies. The thesis presents the design and implementation of the solution, along with evaluations of the different data compression methods.

Test setup with two Kasadakas

The application is validated in two real-world ICT for Development (ICT4D) cases that both use the Kasadaka platform: 1) An extension of the DigiVet application allows sending information related to veterinary symptoms and diagnoses accross different distributed systems. 2) An extension of the RadioMarche application involves the retrieval and adding of current offerings in the market information system, including the phone number of the advertisers.
