Conclusion
• Scalable and real-Eme contextualisaEonof IoT data has thepotenEal tosignificantly improve data processing for large scale IoT applicaEons inSmartCiEes
• Weproposedanapproach to contextualise andquery Internet scale IoTdata and we exemplify the approach via a smart parking spacerecommenderapplicaEonforSmartCiEes.
• Theexperimental scenario in thispaper illustrates that contextualisaEonof IoTdatareducesqueryEmesfor IoTservices(suchasasmartparkingspacerecommender)bymorethan3EmesincomparisonwithasituaEonwherethequeryiscontextualisaEonagnosEc.
