Abstract: An event information processing method of processing event based information in an event information processing system for organizing and accessing event information includes steps of acquiring event based information from at least one information source, wherein event based information comprises attributes associated with topic, time, and location, and identifying topical, temporal, and location attributes from the event information that are used to organize the event information for selection and correlation with other event information. Topical, temporal, and location attributes are extendable by means of a topical hierarchical category resource, location and temporal hierarchical category resources or by application specific attribute information. The event information is storable in an event repository along with its topical, temporal, and location attributes.
