24. An event analysis system comprising: a network interface; an information database; an event database; a memory comprising: an information source model; an environment model which defines a first model entity and a focus entity; an event model which defines events; an event implication model and an event detection engine; an event implication engine; and an event processing control program comprising instructions which: read the information source model to determine information sources; retrieve articles from the information sources and store the articles in the information database; initiate execution of the event detection engine on the articles to detect events represented in the articles, generate event objects according to a common event structure which is independent of the information sources, and store the event objects in the event database; initiate execution of the event implication engine on the event objects to determine an inferred event on behalf of the focus entity in view of a focus relationship, where the event implication engine recognizes that the focus relationship exists between the focus entity and the first model entity and responsively generates the inferred event due to detection of the event involving the first model entity, generate a new event object from the inferred event, and store the new event object in the event database; and initiate communication of the event objects including the inferred event to an external system subscribed to the event analysis system; re-initiate execution of the event implication engine on the new event Object, generate an additional event object, and store the additional event object in the event database; and receive a public interest level value and importance level value for each event, where the event model comprises an event type and event attributes of the event type, and where the new event object and the additional event object each comprise: an event type field; an event type probability field; an importance field; and a public interest field; a processor coupled to the memory and operable to execute the instructions of the event processing control program.
