Roeland Ordelman (PHD, 2003) works at the intersection of computer science, cultural heritage and humanities. With a background in speech technology and information retrieval he has been working for many years on the disclosure of large (audiovisual) heritage data sets at Netherlands Institute for Sound & Vision (NISV, Beeld & Geluid), managing NISV's innovation Labs accommodating for example the CLARIAH Media Suite, workflows for the application of machine learning on a large scale  (e.g., speech recognition, computer vision), and prototypes for investigating conversational search. His research focuses on interacting with large heritage data sets, either from a research perspective (e.g., in the Media Suite) or using (spoken) conversational interaction technology.

  • Senior Researcher at Human Media Interaction, University of Twente
  • Advisor at Netherlands Institute for Sound and Vision, coordinator NISV iLabs and CLARIAH Media Suite
  • CTO of the CLARIAH Research Infrastructure for the Arts and Humanities
  • Chair of the Stichting Open Spraaktechnologie (SoS)
  • Member of the Landelijk Beraad Digitale Infrastructuur (LBDI) for the SSH council.
