Abstract
A semantic publish-subscribe system, including: a plurality of subscribers; a plurality of publishers; and a server that receives and stores subscriptions that are described in web ontology language (OWL) graph patterns from the plurality of subscribers and that receives events that are described in semantic graphs formed by OWL assertions from the plurality of publishers, wherein when the server receives an event from a publisher, the server expands the OWL assertions of the event using a reasoner to produce an expanded event, the server matches the expanded event to a subscription, and then, the server notifies a subscriber whose interest matches the event.
