Ontologies, structured vocabularies and terminologies are used as knowledge organization system (KOS) for building knowledge-based applications. KOS are used for facilitating sharing data and the Linked Open Data initiative has opened new perspectives for integrating heterogeneous data on the web. However, the increasing availability of KOS on the web as well as ad hoc and in-house classifications not yet present in the infrastructure of the Semantic Web raises the question of their identification and reuse. We describe an approach of building cooperative decentralized repositories of ontologies. The approach is being implemented on top ServO (Server of Ontologies), a dynamic ontology repository building tool aiming at indexing and searching KOS and computing similarities between their entities.
