KHealth Asthma Ontology (KAO)

The KHealth Asthma Ontology (KAO) is being designed to deduce abstractions from the asthma dataset provided by the kHealth project.

The overall goal is to achieve the Data, Information, Knowledge, and Wisdom (DIKW) pyramid triangle vision [Sheth et al. CPS Computing 2013].

The asthma dataset collects data generated by IoT devices such as peak flow meter, Foobot, Fitbit, and Web Services (e.g., AirNow) to obtain parameters such as air quality, pollen index, outside humidity, and temperature.

KAO Overview (ONGOING)

The KHealth Asthma Ontology (KAO) ontology is designed and reused the ontologies as follows:

kao Ontology Evaluation (ONGOING)

Kao Ontology used for automatic semantic annotation and reasoning (ONGOING)

The kao ontology is used to semantically annotate the IoT datasaset using Jena, a framework to build semantic web applications.

High-level abstractions (e.g., HighgPollenLevel) can be deduced by executing the Sensor-based Linked Open Reasoning (S-LOR) inference engine based on the Jena inference engine.

S-LOR inference engine is extended to interpret health measurements or any IoT datasets used within the kHealth project.

Kao Ontology: Best Practices with PerfectO (ONGOING)

We follow as much as possible the PerfectO methodology to improve the quality of the ontology and its integration with useful ontology tools to provide automatic documentation, visualization, etc.
