..the basic event-event relations that are defined by three elements, i.e. two different events and a relationship type. We distinguish three basic relation- ship types, corresponding to three of the event properties:

A topological or location-based relationship: two events are related because they involve the same place (e.g., Yo- gyakarta) B conceptual or type-based relationship: two events are re- lated because they involve the same type (e.g., War) C biographical or actor-based relationship: two events are related because they involve the same actor (e.g., Toha).
