Abstract:OWL (Web Ontology Language) is the standard language for Semantic Web and is used in defining ontologies for Web. Temporal event data are ubiquitous in nature. Temporal data can be represented qualitatively using temporal relations in OWL, enabling temporal ordering of events which plays a vital role in task planners. The basic Allen's temporal interval relations can be used to describe relations in OWL. Allen's interval algebra is a well known formalism used to represent and reason the temporal knowledge.

“…Ontologies are required in event models such as Event F [19][19], OntoEvent [16], REseT [25], and LODE [21]. In some cases, as in OntoEvent and REseT, the ontology was created specifically for the event model.…”

Development of smart city services is presently hindered because the data is too heterogeneous, despite the increasing availability of data in open data initiatives. We determined metadata fields and semantics for our proposed model after a survey of other event models, and after its trial implementation in actual applications. Our event metadata model is unique among event models in being extensible as needed. We illustrate our model by showing it with different data types, and we validate it using real-world data in a prototype smart cities service for pedestrian safety. Wide adoption of our event metadata model has the potential to broaden the number and scope of smart city services.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
