This article presents the definition and implementation of ObserveUnB, an observatory of the scientific and academic collaboration network in the University of Brasilia (UnB). ObserveUnB focuses on representing the network and aims to assist the expansion of scientific collaboration through partnership discovery. The ObserveUnB uses information from the Lattes curriculum of UnB researchers, from the research groups certified by UnB listed in the Directory of Research Groups of the CNPq, and from institutional databases. The ObserveUnB project also includes an extension of the Conscientias ontology (a Lattes base) and the definition of a reputational model for network participants.
