Second International Workshop on Definitions in Ontologies (IWOOD 2014)
Held in conjunction with the 5th International Conference on Biomedical Ontologies (ICBO 2014)

Tuesday, October 7, 2014, 1:00 PM – 5:00 PM
Houston, TX, USA

This workshop is a follow-up to the workshop on Definitions in Ontologies (DO 2013) held last year in Montreal in conjunction with ICBO 2013. The focus of this second workshop is on definition practices in either human or machine-assisted ontology development.

Explicit definitions of terms in ontologies serve a number of purposes. Logical definitions allow reasoners to create inferred hierarchies, lessening the burden of asserting and checking the validity of subsumptions. Natural language definitions help to ameliorate the pervasive problem of low inter-annotator agreement. In specialized domains, experts will know their own field well, but may only have limited knowledge of adjacent disciplines. Good definitions make it possible for non-experts to understand unfamiliar terms and thereby make it possible for more confident reuse of terms by external ontologies, which in turn facilitates data integration. 

The goal of this workshop is to bring together interested researchers and developers to explore these issues by presenting case studies in a biomedical domain discussing the difficulties that arise when constructing definitions with a view to sharing strategies in the future. Even in the seemingly narrow domain of definition construction, cross-fertilization from related disciplines should yield benefits in quality and help to identify novel approaches.

*New acronym: we changed the acronym of the workshop to avoid any confusion with the Disease Ontology acronym, also DO.
