How can Open Web Search contribute to digital diversity?
Not only Europe is heavily depending on web services from a few monopolistic economic players. Data is flowing out, value is being lost, and regulation is being undermined. How can we counter this situation with an open web data infrastructure? Which technical and economic concepts promise acceptance and strengthen digital diversity? Which ethical and legal questions need to be answered in this context?
“Boosting Digital Sovereignty” is the ossym2026 conference theme. Join us in Berlin for inspiring talks, thoughtful discussions and latest scientific research findings.
For the eighth time, ossym2026 is bringing together the European and international Open Web Search community.
The hybrid conference provides a forum to discuss and further develop the ideas and concepts of open internet search and related topics such as webdata in the context of AI. The conference comprises various formats including scientific talks, poster sessions, panels, workshops, demonstrations, student engagement and informal discussion spaces. It is aimed at researchers, data centres, libraries, policy makers, legal and ethical experts, and the broader community.
