  2. WhyMeteorology? • PROBLEM: • The investigation of extreme hydrometeorological events requires lots of data from sensors huge data bases. • It is not trivial for meteorologists to create SPARQL queries that involve meteorological data, provenance metadata and also ontology classes. • GOAL: Presentan approach that uses well-foundedontologiesandprovenance management techniques to aidresearchers to investigatethe cause oferroneousvaluesdetectedatanypointofthepre-processingchainofmeteorological data. • Letthemeteorologists to createsimplequeriesevenwithoutknowingthesyntaxofthe SPARQL language.

  3. How? • Using: • Ontologicallywell-founded UML modelingprofile (OntoUML). A profile to developwell-foundedontologiesthatreflectsthestructureandaxiomatizationofUnifiedFoundationOntology (UFO) (Guizzard, 2005). • Open proVenanceOntology (OvO) (Cruz, 2012) to modelMeteoro ontology. • Developing: • A web-basedtoolthatallowstheresearches to navigatethroughtheconceptsandproperties, andgraphicallydevelopsimplequeriesbyselectingfeatureslikeontologyclass, object, propertiesandvalues to besearched.
