As a researcher, I have been working with great pleasure on Computer Science research challenges in the field of Cultural Heritage, Digital Humanities and ICT for Development. My main contributions are in the field of (Semantic) Web science while attempting to embed my research in a social context. My research interests include understanding and innovating the interaction between low-level digital technologies and high-level social processes. Below you find a number of current and past projects that form the context of my research, click on the title to view posts related to the project.

Current projects

  • HEDGE-IoT (2024-2027). HEDGE-IoT is a HorizonEurope project that proposes a novel Digital Framework which aims to deploy IoT assets at different levels of the energy system (from behind-the-meter, up to the TSO level), to add intelligence to the edge and cloud layers through advanced AI/ML tools and to bridge the cloud/edge continuum introducing federated applications governed by advanced computational orchestration solutions.
  • Interconnect– (2019-2024). The Horizon2020 Interconnect envisages to achieve a relevant milestone in the democratization of efficient energy management, through a flexible and interoperable ecosystem where distributed energy resources can be soundly integrated with effective benefits to end-users.In this project, we collaborate with TNO on further developing the SAREF ontology and developing machine learning solutions on smart-home knowledge graphs.
  • CLARIAH(-PLUS) (2019-…). CLARIAH-PLUS builds further on the mission of CLARIAH (2015-2019): to enhance and support digitally enabled research in the humanities and social sciences at large. CLARIAH and CLARIAH-PLUS aim to develop and maintain a basic infrastructure in support of ICT-based research practices. CLARIAH-PLUS will integrate and expand the area of the earlier defined focus areas of Linguistics, Socio-Economic History and Media Studies and will further develop new technical, analytical and user-friendly applications for textual datasets.
  • InTaVia: In this H2020 project, we are making linked cultural heritage data usable for end-users
  • Pressing Matter: Our role in this NWO project is about developing data models to support societal reconciliation with the colonial past and its afterlives.
  • Hybrid Intelligence: Augmenting Human Intellect. In this project, I act as co-promotor for two projects:
  • CARPA: responsible production using crowdsourcing in Africa. This is an NWO-WOTRO funded project housed at the Universiteit van Amsterdam

Previous projects

  • ArchiMediaL (2017-2020) . The project will combine image analysis software with crowdsourcing and semantic linking to create networks of visual resources which will foster understanding of understudied areas in architectural history. More information at
  • SCORE! (2018-2019) is a NWO-KIEM project. Video allows us to look back to a time gone-by. For heritage institutions, moving images present a new challenge for engaging interaction. Previously, video has been mostly used unmodified as a citation or chopped up as a remix. But there is
    far more information, encoded deep within videos than what we see on the surface. If it were possible to extract this information, this high-level information, what would be possible for the creative sector and heritage sector alike? With this project, SCORE!, we plan to examine exactly that. More info at
  • Ariadne (2013-2017) was an EU FP-7 project that brings together and integrates existing archaeological research data infrastructures so that researchers can use the various distributed datasets and new and powerful technologies as an integral component of the archaeological research methodology. In this project we developed technologies for building Archeology Knowledge Graphs and investigated the feasibility of data mining  on these knowledge graphs.
  • Big Data Europe (2014-2018) The Horizon2020 Big Data Europe project will undertake the foundational work for enabling European companies to build innovative multilingual products and services based on semantically interoperable, large-scale, multi-lingual data assets and knowledge, available under a variety of licenses and business models.
  • BiographyNet (2013-2016) BiographyNet is a multidisciplinary project that combines expertise from history, computer science and computational linguistics. The project is a collaboration between the Netherlands eScience Center, Huygens ING and VU University Amsterdam
  • CLARIAH (2015-2019) The Common Lab Research Infrastructure for the Arts and Humanities, is a distributed research infrastructure for digital appliactions and data for humantes and social science researchers. In Work Package 2, we are working on developing appropriate Linked Data infrastructures and interconnected datasets around People, Places and Concepts. In Work Package 5, we collaborate with media researchers on developing an integrated Media Suite. The DIVE project is part of this effort.  See also other Clariah items on this page.
  • DIVE and DIVEplus (jul 2014-2018) In the DIVE project, we will be looking at providing event-based browsing of (audiovisual and other) cultural heritage content. This content is extracted using automated methods and crowdsourcing. Check out our live demonstrator at
  • GTOU (2016) was a project funded by the Taalunie, focusing on establishing cross-national links between audiovisual thesauri. In this project we use interactive alignment to establish these links and then through an information retrieval application show the benefits of such connections.
  • Observe (2014-2016) In the OBSERVE project, we looked at how interactive content for public screens can be modelled. These content and context models could be used for automated content selection or recommendation.
  • Dutch Ships and Sailors (mar 2013-apr 2014) As a sea-faring nation, a large portion of Dutch history is found on the water. However, much of the digitized historical source material is still scattered across many databases and archives. This curation and demonstrator project aims to bring together the rich maritime historical data preserved in the many different databases. We propose a (semantic) web-based infrastructure that will house various maritime-historical datasets. We will provide a tool chain and methodology for convvery unofficial logo of DSSerting legacy datasets. The infrastructure includes common vocabularies to normalize and enrich existing data. Links are established between the datasets and to other relevant datasets on the Web. Although the infrastructure will be set up to facilitate 25+ identified datasets, we initially populate the infrastructure with four selected datasets. These will allow us to investigate two case studies in order to answer the historical research question “To what extent did patterns of shipping and recruitment in the Dutch maritime sector change over the course of the 18th and 19th centuries?”
  • Inclusive Insight (2014) was an NWO KIEM project where we looked at the potential benefits of Semantic technologies to establish a heterogeneous knowledge graph around agricultural data, documents, organizations and people.
  • VOICES (2011-2014) Since June 2011 I am also involved in the VOICES project, headed at the VUA by Hans Akkermans, in this project we are building voice-based mobile web services for rural Africa. A related project is Web for Regreening in Africa (W4RA). Our first us
    e case uses voice-based services to support local farmers. This leads to the so-called RadioMarché service, which is a local market information system that integrates GSM, ICT and Radio technologies.
  • Verrijkt Koninkrijk (feb 2012-mar 2013) Dr Loe de Jong’s Het Koninkrijk der Nederlanden in de Tweede Wereldoorlog remains the most appealing history of German occupied Dutch society (1940-1945). Published between 1969 and 1991, the 30 volumes still combine the qualities of an authoritative work for a general The famous row of books produced by Loe de Jong (foto, and an inevitable point of reference for scholars. Ths project partners are NIOD Institute for War, Holocaust and Genocide Studies (NIOD), University of Amsterdam (UvA), Vrije Universiteit Amsterdam (VUA), Meertens Institute and Data Archiving and Networked Services (DANS-KNAW). The VUA part consists of constructing vocabularies out of OCR’ed indices and Named Entity Recognition results. These will be mapped to in-house thesauri as well as external Linked Data sources.Visit the VK semantic layer
  • Furoba Blon (jan 2012-dec 2012) The Voices/W4RA team received additional funding by winning the IPI news contest. This will allow us to use much of the same techniques in a new use case: voice based citizen journalism in the Sahel region. The project has been named Foroba Blo, Furoba literally means “big field” or “collective field” but the signification is “for everyone” Blon = the vestibule where the chief holds his audience. Together they signify the large room or space where everyone has the right to speak in front of the chief; the truth can be told; but only if you do it respectfully, without insulting anyone.
  • EuropeanaConnect (2010-feb 2012) Previously I worked on the EuropeanaConnect project, where we try to convert and align existing data and metadata sources for European cultural heritage institutions to semantic structures. EuropeanaConnect is a technology provider for the Europeana project. Within this project, I worked on the conversion of data to the Europeana Data Model (EDM), examples include the data from the Amsterdam Museum, which is now available as Linked Open Data. I am also involved in the development of an interactive and transparant tool for vocabulary alignment, Amalgame (Amsterdam Alignment Metatool)
  • MultimediaN E-culture From 2003-2008 I was a Ph.D. student at the UvA under supervision of Bob Wielinga and Maarten van Someren at the Human-Computer Studies Lab of the University of Amsterdam (UvA). During that period I contributed to the MultimediaN E-culture project. I received my Ph.D. in september 2010. The title of my Ph.D thesis is “Ontology Enrichment from Heterogeneous Sources on the Web”
  • Siteguide (2008-2010) From 2008-2010 I worked as a postdoctoral researcher on the SiteGuide project where I developed methods and tools for automatic assesment and recommendation for web site authoring and design.
