We investigate performance variability phenomena in OWL ontologies, and present methods to identify subsets of an ontology which are performance-degrading for a given reasoner. Expand

The OWL reasoner evaluation (ORE) workshop brings together reasoner developers and ontology engineers in order to discuss and evaluate the performance and robustness of modern reasoners on OWL ontologies. Expand

The OWL Reasoner Evaluation competition is an annual competition (with an associated workshop) that pits OWL 2 compliant reasoners against each other on standard reasoning tasks over naturally occurring problems. Expand

FishBase is an important species data collection produced by the FishBase Information and Research Group Inc (FIN), a not-forprofit NGO with the aim of collecting comprehensive information (from the taxonomic to the ecological) about all the world’s finned fish. Expand

In spite of the recent renaissance in lightweight description logics (DLs), many prominent DLs, such as that underlying the Web Ontology Language (OWL), have high worst case complexity for their key inference services. Expand

We present WebProtégé, a cloud-based application that allows users to collaboratively edit ontologies represented in the Web Ontology Language (OWL). Expand

A fine-grained analysis of asserted axiom dynamics throughout the evolution of the NCIt from 2003 to 2012. Expand

The National Cancer Institute (NCI) Thesaurus (NCIt) is a biomedical ontology which has been developed for over a decade. Expand

The analysis of changes between OWL ontologies (in the form of a diff ) is an important service for ontology engineering and their understanding of changes carried out between ontologies. Expand

The detection of changes between OWL ontologies is an important service for ontology engineering. Expand
