A processing system and method for uncertain complex events

Abstract

The invention discloses an uncertain complex event processing system and method. The method comprises the steps that uncertainty of elementary events and rules is represented in a formal language mode; events subjected to formal language description are received by an event detection module and successively combined with all events in an event storage module according to an event arrangement relationship in the event storage module; a rule, subjected to rule semantic representation, in a rule base is inquired, if a combined event sequence meets the requirement of the rule, a probability complex event is generated, and the probability of the complex event is obtained by conducting reasonable calculation through the event probability and the rule probability; if the combined event sequence does not meet the requirement of the rule, the event sequence is stored in the event storage module according to an event storage rule. By means of the uncertain complex event processing system and method, uncertain complex events can be processed scientifically, the requirements of the event processing system on efficiency and reliability in use are met, and the good application prospect is achieved.

Description

technical field [0001] The invention relates to a processing system and method for uncertain complex events, belonging to the technical field of event processing. Background technique [0002] Events are objects used to record activities in the system. Events may be related through time, causality and aggregation. The aggregation relationship is defined as follows: If the activity represented by event A is composed of a group of events B 1 , B 2 , B 3 ...B n represented by the activity composition, then the A event is all B i An aggregation event of (i=1, 2, 3...n) events, A event is also called a complex event. There are two reasons for the uncertainty in complex events. One is that the basic events themselves have greater uncertainty, and the complex events they form have uncertainty. For example, in many real situations , the original event directly read by the sensor is an uncertain event; the second is that the rule is inaccurate when the basic event is aggregated ...
