Motivation and objectives

Developing ontologies is not an easy task and, as the ontologies grow in size, they are likely to show a number of defects. Such ontologies, although often useful, also lead to problems when used in semantically-enabled applications. Wrong conclusions may be derived or valid conclusions may be missed. Defects in ontologies can take different forms. Syntactic defects are usually easy to find and to resolve. Defects regarding style include such things as unintended redundancy. More interesting and severe defects are the modeling defects which require domain knowledge to detect and resolve such as defects in the structure, and semantic defects such as unsatisfiable concepts and inconsistent ontologies. Further, during the recent years more and more mappings between ontologies with overlapping information have been generated, e.g. using ontology alignment systems, thereby connecting the ontologies in ontology networks. This has led to a new opportunity to deal with defects as the mappings and other ontologies in the network may be used in the debugging of a particular ontology in the network. It also has introduced a new difficulty as the mappings may not always be correct and need to be debugged themselves.

Topics of interest

This workshop intends to be a forum where issues in debugging ontologies and mappings between ontologies are discussed. Topics of interest include, but are not limited to:

  • detecting and repairing semantic defects in ontologies
  • detecting and repairing modeling defects in ontologies
  • detecting and repairing defects in the structure of ontologies
  • detecting and repairing defects in mappings between ontologies
  • debugging ontology networks
  • debugging modular ontologies
  • justifications
  • belief revision for debugging
  • ontology patterns for debugging
  • interactive ontology debugging
  • visualization for ontology debugging
  • connection of ontology debugging with other ontology engineering tasks (e.g. ontology development, ontology alignment, ontology comprehension, ontology sense making, ontology evolution, ontology enrichment)
  • case studies
