It is particularly challenging to explain PhD research to family and friends, especially in an abstract field such as Computer Science. In the following blog post I will try to explain my PhD, freed from academic precision and more from the big picture and with plenty of examples.


At the end of November 2019 I could visit the sunny California to attend the Conference on Knowledge Capture (K-Cap). A lot of interesting workshops, tutorials and talks covered topics such as the representation of knowledge in Wikidata, approaches to transform tabular data to Linked Data, or the representation of scientific literature and processes as Knowledge Graphs. Additionally I could present our work on MontoloStats. Continue reading for the full trip report!


In the last week of October 2019 I attended the International Semantic Web Conference (ISWC) in Auckland, New Zealand. I had the honor to present my PhD plan at the ISWC Doctoral Consortium. In this blog post I talk a bit about the conference and focus on a few presentations I found particular interesting or relevant for my PhD regarding guidelines for the design and use of ontologies.


In the first week of July I participated the first edition of the International Semantic Web Research Summer School (ISWS) in Bertinoro, Italy. It was an exciting event, where I had a lot of fun and learned also a lot! Continue reading for the full travel report.


For the ISWS summer school I prepared an interactive poster. Read in his post what it is about and see how it was made.




The Royal Library of Belgium (KBR) has launched the BESOCIAL project, a two-year project that aims to set up a sustainable strategy for archiving and preserving social media in Belgium. The challenge is equally complex as the data: social media are challenging from the point of view of conservation, preservation and accessibility. This is due to their uniqueness and ephemeral nature in particular.

FAST tracking e-government deployment through automated customer journey development

Complicated rules, multiple contact points, numerous forms and applications and three administrative levels: processes as common as home renovations in Flanders require a lot of manual administrative work. To streamline customer journeys and simplify processes, municipalities and other public organizations would benefit from e-government applications. However, implementing these solutions is challenging, considering the lack of well-structured content and the need to integrate legacy systems. FAST aims to tackle the challenges to e-government adoption by creating an engine to automatically generate customer journeys from existing unstructured content – the ideal collection of digital interaction points between public services, organizations and citizens – for a range of public tasks.

Ecosystem for Data management of Local publishers

Media companies in Flanders today have fragmented consumer data, with each company maintaining its own data management platform. As a result, data remains largely undervalorized. The EcoDaLo project aims to develop a knowledge platform for publishers allowing the integration of many diverse data sources. It will also define a business model for cooperative data products that complies with regulations and guarantees data ownership and privacy protection. These outcomes will lead to increased scale and thus competitiveness of local media companies, a healthier media ecosystem and a framework for other sectors in need of new ways of leveraging data.

LEarning analytics for AdaPtive Support

The purpose of the LEAPS project is to develop a self-learning analytics system for adaptive learning. This support system can be integrated into assistive software for struggling readers, supportive software for professional communication, and educational games. In the consortium, partners with a wide range of expertise will work together, including statistics, computer, educational and cognitive sciences, human-computer interaction, software engineering and educational publishing. This highly interdisciplinary collaboration will help create a much needed and marketable solution.
