Researchers at the University of Karlsruhe, one of Germany's leading academic institutions in science and technology, have built a newsEvent ontology to describe events and entities in a business news context. The goal is to provide aggregated, relevant news to traders in financial markets.
OpenCalais provides the annotations for clustering similar entities, events, and facts. This is the starting point for defining the concepts that should be represented in the ontology. The newsEvent ontology formalizes the information and contributes background knowledge beyond that provided by OpenCalais.
