Ontology design patterns and semantic abstractions in ontology integration.

This paper describes a hackathon event that took place as part of the Ontology Summit in 2014. The purpose of this hackathon was to develop an integrated ontology for a potential travel risk application, and was intended as an exercise in ontology integration and re-use. The hackathon took place over a 48 hour period via remote teleconferencing. Several existing ontologies and ontology design patterns were integrated into one common framework, while a new ontology was developed from available data and integrated with these. The notion of ` event' as it relates to risk presented some interesting ontological issues that are described here. This paper describes the work that took place, gives a brief overview of the ontology content, and concludes with lessons learned on the opportunities and challenges in re-use of ontologies from different sources, including the implications of different ontological commitments. The final work product was substantial enough to form the basis of a possible travel risk application.
