The ICARUS ontology has been developed as a key component of the ICARUS project, which has received funding from the European Union’s Horizon 2020 research and innovation program. The ontology has been developed specifically to address the challenges involved in integrating and semantically enriching aviation-related data from the three core ICARUS tiers, which are in different formats and from different data sources.
It is expected that the ICARUS ontology would help to promote data-driven collaboration between domains directly or indirectly linked with the aviation sector. It is also anticipated that the ontology would bring a common understanding for data assets from diverse domains such as Aerospace, Retail and Weather. The intended uses of the ICARUS ontology are data mapping, data linking, and data recommendation.
The team behind the development of the ICARUS ontology used a multi-layer approach to ensure that it could represent both metadata and aviation-specific concepts. More specifically, the team used a design process that was a judicious mix of the various approaches used to extend existing ontologies or to develop new ontologies.
The ICARUS ontology can be easily maintained and extended during the ICARUS platform operation as new individual domain ontologies could be added under the top-level ontology. Furthermore, it can answer several different competency questions that can be useful to the aviation industry domain. At the moment, the ICARUS ontology consists of 132 classes, 134 object properties, and 406 data properties.
Overall, the ICARUS ontology has been able to capture the structural and semantic characteristics of the various entities involved in the aviation domain. The underlying conceptual models facilitate the use of lightweight reasoning during the matchmaking process. The ontology can be utilized to search the integrated data using SPARQL queries. Additionally, by leveraging a semantic recommendation system, the ICARUS ontology provides high-quality recommendations of datasets, based on users’ preferences.
A detailed description of the ICARUS Ontology is provided in the ICARUS Deliverable D1.3 (Updated ICARUS Methodology and MVP).
