Abstract
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.
