The Royal Institute Elcano (Real Institutor Elcano: www.realinstitutoelcano.org) in Spain is a prestigious independent political institute whose mission is to comment on the political situation in the world focusing on its relation to Spain. As part of its dissemination strategy it operates a public website. The online content can be accessed by navigating through categories or by a keyword-based, full text search engine. We have used the meaning of concepts and relation of the International Affairs domain. In addition to an automatic ontology-based annotation, the portal includes a semantic search engine with a natural language interface, a web publication tool allowing sematic navigation, and a 3D visualization component. The sematic portal is currently being tested by the Institute.
