ViewpointS enables representation and storage of individual viewpoints in a shared knowledge graph. Knowledge providers (i.e., agents) express their individual opinions by emitting viewpoints on the semantic similarity or proximity between resources of the knowledge graph which can either be agents, documents (i.e., knowledge supports) or concepts (i.e., descriptors). We first briefly recall the ViewpointSknowledge representation formalism and discuss the genericity it enablesin terms of semantic distance computation.In this paper, we benchmark the ViewpointSapproach againstother classic semantic distances(graph based or information content based) on a WordNet experiment. Our goal is to demonstrate the value of keeping the subjectivity of the represented knowledge, while having a generic approach that can handle any kind of knowledge and compute similarity between any kindsof objects.
