OntoFarm Project

This page is deprecated and no longer updated. For its new version see http://owl.vse.cz:8080/ontofarm/


This small-sized project of KEG 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.

All ontologies can currently be downloaded from the site of the track of OAEI 2010.

Contributions to the collection are warmly welcome!

The project achieved the following results (as of July 2009, update to come!):


The project has been partially supported by several research projects:
