Ontofarm dataset
This small-sized project of SWOE aims at developing a collection of richly axiomatised 'parallel' ontologies in OWL and carrying out various experiments on them. All ontologies model the same domain, that of conference organisation, based on different conferences and, especially, conference support tools. Most ontologies contain some modelling errors, and reflect different conceptualisations of the same domain, this way simulating 'real-world heterogeneity' of semantic web ontologies.
News: If you use the conference (OntoFarm) ontologies in your work, please cite new paper about OntoFarm [4]: Zamazal, O., Svátek, V. (2017). The Ten-Year OntoFarm and its Fertilization within the Onto-Sphere. Web Semantics: Science, Services and Agents on the World Wide Web, 43, 46-53.
All ontologies can currently be downloaded from this site in two variants see below in section Ontologies.
