Gamesourcing Expert Painting Annotations
Online collections provided by museums are increasingly opened for contributions from users outside the museum. These initiatives are mostly targeted at obtaining tags describing aspects of artworks that are common knowledge. This does not require the contributors to have specific skills or knowledge. Museums, however, are also interested in obtaining very specific information about the subject matter of their artworks. We present a game that can help to collect expert knowledge by enabling non-expert users to perform an expert annotation task. This is achieved by simplifying the expert task and providing a sufficient level of annotation support to the users. In a user study we could prove the usefulness of our approach.
