Diving into cultural data

Help the culture and media sector in the Netherlands to make optimal use of innovations in data science and AI. That is what drives the work of Laura Hollink, group leader of the Human-Centered data science group at CWI. ‘Since the cultural sector upholds high moral standards, it is the perfect context to research how AI and data science impact real people in the real world.’

What is your group’s research about?
‘Our main research question is how to responsibly apply AI and data science in the culture and media sector. That sector is characterized by high ethical standards and clear moral principles. We translate those high level principles like inclusivity or transparency into demands for the AI pipeline. And we evaluate to what extent certain data science methods can help cultural heritage organizations achieve their goals.’

What kinds of topics do you study?
‘One of our projects is on the use of controversial terms in cultural heritage collections. Since those collection datasets may be the basis for AI systems that produce automatic descriptions or query extensions, it would be good to be able to automatically detect at a large scale which terms are controversial given the context that they are in . A second project is about evaluating the inclusivity of a recommender system for libraries, assessing for example whether or not it favors authors from a specific gender or origin.’

Could you name any striking results?
‘In a study on the online newspaper archive Delpher we were able to identify distinct search patterns depending on people’s interests. We discovered that people looking for WOII-related subjects use very complex search behaviour, whereas people interested in their ancestry typically have short sessions with only a couple of simple queries and very little clicks or downloads. These results lead to recommendations to digital archives on how to best support the different search behaviours of their users.’

What is the biggest challenge in this field?
‘Combining heterogeneous and often cross-media collections, data modelling, and semantic search. Our data consists of physical objects, short pieces of texts in natural language, newspapers, audiovisual archives… And they do not always completely meet our purpose. For example, in the book recommender project, we have data about which people read which books. But we do not have any information about the authors. A lot of our work therefore involves finding smart ways of combining datasets to distill the information we need.’

Your group is part of two larger scale research labs. What is their added value?
‘Both the Cultural AI Lab and the AI, Media and Democracy Lab bring together different scientific disciplines and societal organizations to collaborate for the longer term. That allows us to build a deep mutual understanding for each other’s language, challenges and expertise, which is essential if you want to make true impact.’
