DESCRIPTION

Basic Formal Ontology is currently being used by over 100 ontology-based research projects in biomedical informatics and increasingly in other fields. The course will provide an introduction to the content and use of BFO in ontology development. Attendees will acquire knowledge of the ontology and of its use as top-level ontology in multiple ontology development projects in a variety of fields. They will learn about the most recent developments in the ontology and acquire basic knowledge of the draft version 2.0.

The current version of the draft Specification and User Guide for BFO 2.0 is available here.

The current version of the draft BFO 2.0 OWL file is available here. Please read the release notes

FACULTY

Barry Smith is a prominent contributor to both theoretical and applied research in ontology. He is the author of some 500 publications, and his research has been funded by the National Institutes of Health, the US, Swiss and Austrian National Science Foundations, the US Department of Defense, the Volkswagen Foundation, and the European Union. In 2010 he was awarded the first Paolo Bozzi Prize in Ontology by the University of Turin. Smith is one of the principal scientists of the NIH National Center for Biomedical Ontology, a Scientific Advisor to the Gene Ontology Consortium, and a PI on the Protein Ontology and Infectious Disease Ontology projects. He has organized over 100 ontology conferences, workshops and tutorials.

Alan Ruttenberg was a Principal Scientist at Creative Commons for 5 years and is now the Director of the University at Buffalo Clinical and Translational Data Exchange. His project, the Neurocommons, prototypes the use of Semantic Web technology for integrating and querying biomedical knowledge, working on structuring and using biological and clinical knowledge to answer questions and computationally interpret experimental data. He is a Coordinating Editor of the OBO Foundry and a former chair of the OWL Working Group.
