Link-enriched video can support users in informative processes of environmental opinion-forming and decision-making. To enable this, we need to specify the information that should be captured in an annotation schema for describing the video. We conducted expert interviews to elicit users’ potential information needs. We carried out a user survey to assess the relevance of the identified information types. Finally, we observed users’ behaviour and needs when presented with a selection of video segments. Our results indicate that certain types of information about the environmental problem, the opinions expressed, the people expressing them and the sources are more relevant for users.
