The Semantic Technology Information Day at the last OMG meeting included a short spiel on Complex Event Processing, relevant semantic models for CEP, and some of the appropriate standards (ODM or Ontology Definition Metamodel, and PRR or Production Rule Representation).
The talks were much more interesting than one would expect from a seminar containing the word “Semantics” in the title (especially for those used to dry, academic claims from the Semantic Web community). For example, Chris Welty of IBM (also co-chair of the W3C RIF effort) started the proceedings with an actually interesting and relevant talk on the role of semantics and knowledge in information systems; the other interesting talks included, for example, the complexities of healthcare ontologies. Presentations will eventually be up on the OMG site.
The main way semantic models like OWL can influence the IT models of CEP is via ODM, mapping ontologies to UML Class and Event and their related and dependent behaviors (State, PRR, etc). In addition, run-time semantic models can potentially assist with things like text analytics.
