Mikko Rinne, M.Sc.(Tech.), will defend the dissertation "Event Processing Using Semantic Web Technologies" on 1 September 2017 at 12 noon in Aalto University School of Science, lecture hall T2, Konemiehentie 2, Espoo.
The dissertation studies hierarchical processing of structured events, where conclusions of higher levels of abstraction can be formed out of patterns of large numbers of simple event objects. Using rule-based reasoning, as supported by Semantic Web technologies, pre-existing entailment regimes can be used for filling in missing event information and for error detection.
The explosive growth of information produced both by networked sensors and as results of other transactional events has lead to a situation, where the capability for fast online processing of large quantities of events is becoming a critical advantage for competition. The increasing need to combine streams of information from heterogeneous sources emphasizes the importance of managing different conceptual approaches.
In this study methods for hierarchical processing of patterns of structured events have been developed. Tangible conclusions of higher layers of abstraction are formed out of larger quantities of simple lower layer events. The tested Semantic Web technologies offer ready-made tools for managing conceptual differences from multiple sources and for rule-based reasoning, which can be used e.g. to fill-in missing event data or to detect errors.
With the presented rule networks and tests it is shown that the studied technologies RDF and SPARQL have sufficient capabilities to serve as the basis of even complex hierarchical event processing applications. One studied application is the detection of counterfeit and theft in pharmaceutical manufacturing. Other application areas, which can benefit from event stream processing, are for example traffic, retail, investment markets, farming, emergency response and health services.
