Kasadaka as presented by AOPP
From 7-9 May 2016, the second TMT-AOPP workshop was held in Bamako, Mali. This workshop was held in the context of the Tailor Made Training project that VU Amsterdam participates in together with the Malinese farmer organization Association des Organisations Professionnelles Paysannes (AOPP).
During the workshop, which was attended by around 25 AOPP members from all over Mali, we followed up on the results of a previous workshop in 2015, where we co-developed a number of use cases around improving the lives of rural farmers in Mali. Specifically, we developed two prototypes services accessible using simple mobile phones:
- An online marketplace for seeds. Farmers can call in to the system to place offerings of seeds or browse current offers of seeds of various quality levels in a specific region.
- A chicken vaccination service. For this service, an extension worker can register newly born chickens in the system. The system keeps an administration of when farmers need to vaccinate their chickens against specific diseases. The system then calls the farmer and plays a reminder message in his/her language.
These services were developed on Kasadaka, the cheap and low-resource rapid-prototyping platform for knowledge-rich and voice-accessible services. During the workshop we were able to further test the Kasadaka in the field. A field trip to local farmers and a milk cooperation in nearby Ouelessebougou gave us further context and information in how these services can support locals (see also the video embedded below). Chris van Aart from 2coolmonkeys demonstrated his progress on the Senepedia wiki and two Android applications that allow farmers and organizers to use geo-services to count cows, trees or other objects in the field.

In addition to these two services, we also presented seven services on the Kasadaka, developed by students of the VUA ICT4D M.Sc. course. These included a weather information service, two vetirenary services, general-purpose knowledge sharing platforms, farmer alert services and a milk market. These services were all very well received and allowed the workshop participants to really see the full potential of voice-enabled information services.
The presentation below shows more information, my personal highlights from the workshop (hence the title) as well as feedback received on the seven student projects.
As the Big Data Europe project enters its second year, we’re doing everything we can to make it as simple as possible to get acquainted with the platform which is under development, and facilitate future deployments of our platform to support your Big Data pipelines.
We are therefore happy to introduce this quarterly series of technical webinars, where you can keep track of progress related to our technical developments and demonstrators in each of the seven societal challenges, ask questions, and provide valuable feedback. In addition, we will also cover other important developments in the area which are not necessarily related to our project.
Online Webinar: 02-03-2016, 14:00-15:00 CET
In the first webinar in this series, you will learn about:
- the requirements we collected from the 7 Societal Challenges we are addressing
- the technical building blocks of our Big Data Platform
- how the above will be provided as a generic instance for customisation
- an introduction to the 7 selected Pilot partners and the expected outcome
The one hour webinar is run by the Big Data Europe Project and presents inputs and presentations from experts responsible for the architecture, the implementation and the upcoming pilots roll-out. The audience will be given a chance to interact and the top questions will be answered by one of our dedicated technical and domain experts.

We are looking forward to your participation.
DOWNSCALE 2013, the 2nd international workshop on downscaling the Semantic Web was held on 19-9-2013 in Geneva, Switzerland and was co-located with the Open Knowledge Conference 2013. The workshop seeks to provide first steps in exploring appropriate requirements, technologies, processes and applications for the deployment of Semantic Web technologies in constrained scenarios, taking into consideration local contexts. For instance, making Semantic Web platforms usable under limited computing power and limited access to Internet, with context-specific interfaces.

The workshop accepted three full papers after peer-review and featured five invited abstracts. in his keynote speech, Stephane Boyera of SBC4D gave a very nice overview of the potential use of Semantic Web for Social & Economic Development. The accepted papers and abstracts can be found in the downscale2013 proceedings, which will also appear as part of the OKCon 2013 Open Book.
We broadcast the whole workshop live on the web, and you can actually watch the whole thing (or fragments) via the embedded videos below.
After the presentations, we had fruitful discussions about the main aspects of ‘downscaling’. The consensus seemed to be that Downscaling involved the investigation and usage of Semantic Web technologies and Linked Data principles to allow for data, information and knowledge sharing in circumstances where ‘mainstream’ SW and LD is not feasible or simply does not work. These circumstances can be because of cultural, technical or physical limitations or because of natural or artificial limitations.
The figure illustrates a first attempt to come to a common architecture. It includes three aspects that need to be considered when thinking about data sharing in exceptional circumstances:
- Hardware/ Infrastructure. This aspect includes issues with connectivity, low resource hardware, unavailability, etc.
- Interfaces. This concerns the design and development of appropriate interfaces with respect to illiteracy of users or their specific usage. Building human-usable interfaces is a more general issue for Linked data.
- Pragmatic semantics. Developing LD solutions that consider which information is relevant in which (cultural) circumstances is crucial to its success. This might include filtering of information etc.

Last week, I presented our work on the Verrijkt Koninkrijk project at the E-humanities workshop in the Soeterbeeck monastery which was organised by the university of Nijmegen and the e-humanities group of KNAW.
It was a very pleasant get-together with some nice talks and hands on sessions. Alice Dijkstra from NWO presented a number of opportunities for getting funding for e-humanities projects. She mentioned some obvious candidates (vernieuwingsimpuls,…) and some less obvious ones (the hopefully upcoming CLARIAH programme, which would continue CLARIN and DARIAH).
The two hands on sessions were nice but showed that there is a more general issue with e-humanities that ‘nice tools’ are being developed but that these tools remain solutions to a single problem. Next to that they are either nice from a computer science or from a historical science viewpoint but it is hard to do exciting comp.science and historical science at the same time. This is reenforced by the issue that historical scientists rarely know what type of tools they want at the beginning of a project. A more interactive and cyclical approach makes sense for both parties. The BiographyNet idea of putting the researchers from different backgrounds in the same room would be one solution. The other in my view is the development of more general-purpose query environments .
In my poster presentation I showed how I tried to do that with Verrijkt Koninkrijk and I think for a more or less generic data analysis interface is also a good idea.
