Elisa Kendall from Sandpiper and Dr Mohammad Ketabchi from Progress were my honorable partners on the Semantic CEP Panel at SemTech today. Q&A covered some interesting questions:
– isn’t the event pattern – decision – reaction view too simplistic?
This was complaint about the “simplified view of the world” slide I presented. Of course, being “simplified” it did not cover, for example, possible multiple levels of abstraction or feedback loops, while learning and update mechanisms are certainly still applicable.
– managing explosion of outgoing events – won’t reaction events potentially overwhelm an event bus?
Usually CEP is “reducing” numbers of simple events (observations etc) into a fewer number of complex / business events – so while this could be a problem, it tends not to be in most practical applications and/or can be managed through the middleware layer.
– what next for financial event processing?
Increased regulatory compliance rules will be applied to more financial operations and transactions by both banking and government agencies… probably a growth area for CEP technologies!
– surely semantic is not just limited to “static” ontology definitions – consider for example ontologies of actions and events?
This was against in introductory slide showing semantic community focus with the “FOAF” type logical relationships – good for text search problems and such, but less so for business operations and behavior – processes and services… Elisa also commented that dynamic classification was certainly a semantics capability, but was more a research topic in “government applications” rather than a productised capability right now.
