Freshly minted dr. Nana flanked by his two paranimphs receives the laudation from supervisor prof. Akkermans.

On 5 april 2016, Nana Baah Gyan successfully defended his PhD thesis “The Web, Speech Technologies and Rural Development in West Africa, An ICT4D Approach” in front of the reading committee at Vrije Universiteit Amsterdam. Dr. Nana worked as a PhD researcher mostly in the context of the FP-7 VOICES project and was supervised by prof. Hans Akkermans and dr. Victor de Boer.

Nana investigated the history of speech systems in developing countries. He discussed and developed strategies for requirements harvesting for an instance of an ICT4D project under rural conditions, the results of which led to an actual implementation of voice-based ICT tools for rural farmers in Mali.

Nana’s thesis is available online.

His thesis furthermore deals with evaluating the impact of the project on the lives of stakeholders involved as well as the potential such tools and systems hold for future research. The thesis also discusses what ICT4D generally means for education in West Africa and beyond.

You can read more about Nana’s research in his thesis [PDF] or on the http://w4ra.org site.

Mouriba logos

RadioMarcheMannetjeFrom 2010 on, I have been making logos for W4RA-related projects, for example for RadioMarche. I have had some request from people to reuse (parts of) the logo before and I have now decided to publish all the logos and the source files under an open license (CC-zero). This basically means I waive any rights I have.

I think this makes sense as I developed these while subsidised with public (EU) money as a side-project. So feel free to reuse them as you wish. If you do, it is nice (but no legal requirement) to..

  1. not use any of the existing logos directly without adaptation for your project/product/company, but adapt it to avoid confusion
  2. let me know if you are using them, or credit me using something like “Adapted from logos designed by Victor de Boer (http://victordeboer.com)

The PNGs and the source files (in SVG, XCF and AI formats) ara available at https://github.com/biktorrr/MouribaLogos

 

Master project Rianne Nieland: Talking to Linked Data

[This post was written by Rianne Nieland. It describes her MSc. project supervised  by myself]

People in developing countries cannot access information on the Web, because they have no Internet access and are often low literate. A solution could be to provide voice-based access to data on the Web by using the GSM network.

afbeeldingIn my master project I have investigated how to make general-purpose data sets efficiently available using voice interfaces for GSM. To achieve this, I have developed two voice interfaces, one for Wikipedia and one for DBpedia. I have made two voice interfaces with two different kinds of input data sources, namely normal web data and Linked Data, to be able to compare them.

To develop the two voice interfaces, I first did requirements elicitation from literature and developed a user interface and conversion algorithms for Wikipedia and DBpedia concepts. With user tests the users evaluated the two voice interfaces, to be able to compare them on speed, error rate and usability.

African farmers in E-Data & Research magazine

The October edition of the KNAW’s E-Data and Research magazine features an article submitted by Christophe Gueret, Stefan Schlobach and myself on the need for facilitating data sharing in developing regions. Our submission was rewritten into a nice interview-like article, which you can find on page 8 (and copied below). The article is in Dutch.

VOICES video

As the VOICES project is ending, we wanted to wrap up our results in the form of a nice video. The result shows the three systems (RadioMarche, Foroba Blon and Tabale) that have been deployed and tested in Mali, Africa. The video was shot by people from the project and edited by Pepijn Borgwat from Synergique and myself. There is an English and a French version, both are embedded below.

New Scientist article about the VOICES project

This week's cover of New Scientist In this week’s New Scientist, an article written by Hal Hodson about our VOICES project appears. It highlights some of the key concepts and results from the project that focusses on providing voice-based access to information in developing areas. The article is partly based on our Web Science 2013 article. Great to see so much interest in our work!

A new voice-based web system could help, making it easier for illiterate people in Mali and other West African nations to use the internet. The project, sponsored by the European Commission, is called Voices and it has already been used to build an information system for farmers and as a platform for citizen journalism.
