We describe a strategy to support the semantic annotation of contested knowledge, in the context of the Scholarly Ontologies project, which aims at building a network of interpretations enriching a corpus of scholarly papers. To model such knowledge, which does not have ’right ’ and ’wrong ’ values, we are building on the notion of active recommendations as a means to sparkle annotators ’ interest. We finally argue for a different approach to the evaluation of its impact. Categories and Subject Descriptor
