Abstract :
This paper describes ongoing work to construct a knowledge base of politically motivated violent events (PMVE) consisting of a domain ontology and of instance data accessible via a browser and visualization interface. The instance data is semi-automatically extracted from news articles gathered by the online news monitoring system of the European Commission (EMM). There are important interrelations in seemingly unrelated violent events recorded in online news articles scattered through the Web. This information can essentially be re-discovered by gathering and mapping it to a well defined, logical model. This knowledgebase can then deploy an inference mechanism resulting in the discovery of hidden relationships and facts.
