ONTOLOGY-DRIVEN COMPLEX EVENT PROCESSING

摘要

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. A user, unaware of the normally difficult and heterogeneous CEP interfaces, can easily construct requests for event alerts using the described interface and a domain ontology that is appropriate for the user's interest.
