Abstract: Described embodiments relate generally to ontology-driven complex event processing (CEP). When implemented as a computer (105), the computer (105) enables, in communication with a network, user generation and transformation of an event definition into an ontology-based event definition. A computer-implemented transformer component (140) receives the ontology-based event definition, generates event processing instructions and transmits the event processing instructions to a CEP server (150) over the network. The CEP server (150) then observes a plurality of structured messages containing event data and determines whether the event data satisfy all conditions of the event definition and sends an event message responsive to determining that all event definition conditions are satisfied. The described techniques allow an arbitrary high-throughput CEP to be used.

Abstract: Described embodiments relate to a method of ontology-driven querying or programming of at least one sensor. The method comprises generating at a query origin a query or command for execution in relation to the at least one sensor, transmitting the query or command to an ontology transformer over a first network, classifying the query or command according to a domain ontology and one or more predetermined capabilities of the at least one sensor, generating a transformed query or program based on the classified query or command using one or more code fragments stored in a memory accessible to the ontology transformer, transmitting the transformed query or program to at least one sensor node in communication with the at least one sensor for execution of the transformed query or program by the at least one sensor node in relation to the at least one sensor, receiving at the ontology transformer from the at least one sensor node at least one result of the query or program, and returning the at least one result.
