Publishing, Linking and Annotating Events via Interactive Timelines: an Earth Sciences Case Study

Events are a critical entity for documenting information within many domains -and yet they are one class of information that, to date, has been relatively neglected with regard to both publishing on the Semantic Web and semantically annotating. In this paper we describe how we enable the interoperable integration, annotation and linking of information about major events from the earth sciences domain, by adopting a Linked Data approach to major events (earthquakes, tsunamis and volcanic

Firstly we describe the common Event, Timeline, Annotation and TemporalRelation ontologies that we use to enable interoperability and exchange of information about events and the relationships between them. We then harvest data describing major geological events from multiple authoritative sources, map it to our model(s) and publish it as RDF triples to the Web of Linked Data. We then describe the semantic annotation system that we have developed that enables the discovery, retrieval and ontology-based markup of such event data via interactive timelines. The resulting annotations significantly enhance the discovery and re-use of information about major geological events. More importantly these annotation tools enable scientists to document, share and discuss their hypotheses about the temporal relationships between such events.
