This presentation was given for OpenAIRE Tech Clinic webinar on 21 June 2021, focusing on the OpenOrgs tool. Unambiguously identifying organizations involved in the research work may not be a trivial task. Their names can be derived from various data sources, each of which often contains a different version of the organization's name (full legal name, short or alternative names, acronym, and so on) and different metadata fields. In OpenOrgs, data curators can enrich the metadata description of organizations and resolve the ambiguity of duplicates detected with an automated process by stating whether two or more entities correspond or not to the same organization. With these tasks, OpenOrgs users can compensate for the lack of information available and improve the organizations' discoverability.
