This document describes a semantic-driven complex event processing (CEP) approach for delivering personalized information streams from data-intensive monitoring systems. The approach combines semantic web technologies like ontologies and SPARQL queries with CEP engines to analyze runtime events and match them to predefined patterns and rules. An architecture is proposed that uses an ontological model, a runtime event processor using predefined rules, information source adapters to transform data, and an information dispatcher to deliver personalized data to applications. The implementation separates each layer as a Java application and uses technologies like Jena, Drools Fusion, and ZeroMQ for communication.
