Roeland Ordelman research interest is on retrieving information from and interacting with large audiovisual (AV) data sets. Traditionally, decoding AV to semantics (e.g., by means of speech technology or computer vision) has been playing an important role in his research, but also how use scenarios of different types of users (e.g., general public, humanities researchers, heritage professionals) relate to existing and emerging search paradigms (linked data, conversational search) and data-driven access. Since 2021 he is technical coordinator (CTO) of the CLARIAH Research Infrastructure for the Arts and Humanities.Ā 

AtĀ theĀ Netherlands Institute for Sound and Vision, one of the largest audiovisual archives in Europe, his work focuses on innovative products that can be brought from R&D into production, either at the institute or related areas. As a Principal Investigator on Language, Speech and Multimedia Retrieval at theĀ University of Twente, his focus is on more fundamental topics related to speech technology, conversational search and multimedia search & recommendation technology.

He received his PhD in 2003 on the use of speech recognition technology to improve access to audiovisual archives and worked on a wide range of national and international projects in the area of multimedia retrieval. He has been involved in organizing benchmark evaluations in the MediaEval Benchmark Evaluation Series and more recently TRECVid. His current work in this area focuses on the integration of (user) evaluation and benchmarking in the context of ā€˜living labsā€™: research infrastructures that involve industry, research and user communities for mutual benefit.
