Poderopedia is a project that aims to promote greater transparency in Chile by mapping and visualizing the relationships among the country's elite. To achieve this, semantic technologies are being utilized to store and query data. These technologies represent a diverse set of relations between entities (people, companies, organizations) in a flexible way. By identifying the power and influence of people, key Chilean political, civic and business leaders can be identified. OWL (Web Ontology Language) is being used to define the vocabulary because it provides the semantic richness needed.
