The Ten-Year OntoFarm and its Fertilization within the Onto-Sphere

OntoFarm is a collection of heterogeneously structured ontologies describing the same domain (conference organization). It has been repeatedly used for benchmarking purposes within the OAEI conference track, but also in several other projects. Since its inception in 2005, it has undergone several iterations of extension and improvement, especially through addition of pairwise reference alignments. Ten years after the initial launch of the collection seems to be adequate time to collect and summarize feedback on its usage, benefits and shortcomings. Besides the analysis of the involved ontologies proper and of the related literature, we performed a survey among the users of OntoFarm addressing the current role of the OntoFarm collection and its prospects for the future. The majority of respondents intends to keep using the collection in the future, ideally with additional reference alignments.
