33. The method of claim 26 , wherein the translated queries are free from, and lack any reference to, any ontology concepts.
26. A method of configuring a complex event processing (CEP) system in which a stream of events is received via an event bus, each said event having a predefined event type, the method comprising: receiving queries that are to be executable in connection with the CEP system; determining, in connection with at least one processor, whether a received query either initially conforms to a CEP query language executable by an event processing agent, or must be translated from an enhanced query that conforms to a version of the CEP query language that has been enriched so that semantics thereof are represented in accordance with an ontology in order to render it executable via the event processing agent; when the received query must be translated, generating a translated query from the enhanced query in accordance with mappings between concepts of the CEP system and concepts of the ontology, wherein the enhanced query includes references to ontology concepts and the references to the ontology concepts are translated into queries processable by the event processing agent in accordance with the query language; and deploying all queries that initially conform to the CEP query language and all translated queries for possible subsequent execution; wherein the concepts of the ontology are classes, and wherein the generating of the translated query comprises, for the enhanced query: retrieving a class definition for all referenced classes from a corresponding ontology; determining whether the referenced classes are marked as being handled; when the referenced classes are marked as being handled, transforming the respective class definition to the query language, and compiling the translated query; and when the referenced classes are not marked as being handled: when the respective class does not have a corresponding mapping, replacing the class with a union of all of its sub-classes; when the respective class has a corresponding mapping but no sub-classes, removing the reference to the class; and when the respective class has a corresponding mapping and any sub-classes, adding a union with all sub-classes to the class and marking the class as handled.
