Case Studies: 

Case Studies Formalize in RDF the EuroWordNet Synsets and Top Ontology Writing semantic frames in RDF/S as basis for interlingua representations

EuroWordNetTop Ontology: 

EuroWordNet Top Ontology Top Concepts (TC) classify synsets the subset of 1024 Basic Concepts synsets TC are hierarchically ordered by means of a subsumption relation multiple inheritance between TC is not allowed BC can be cross-classified in terms of multiple TC “It is important to realize that the TC are more like semantic features than common conceptual classes” Vossen (2001)

Task 1: 

Task 1 Formalize in RDF/S the EWN TC Creating RDF/S entries for the following synsets and link them to the relevant TC {fruit} #0001 TC: Comestible  Function; ObjectForm; PartComposition; PlantLivingNaturalOrigin {cell} #0002 TC: PartComposition; LivingNaturalOrigin {car} #0003 TC: ArtifactOrigin; ObjectForm; VehicleFunction
