Faculty, staff, fellows and students are welcome to hear a presentation by Dr. Barry Smith, Distinguished Professor of Philosophy; Director, National Center for Ontological Research. Barry Smith is a prominent contributor to both theoretical and applied research in ontology, focusing especially on ontologies in the biomedical field. Basic Formal Ontology (BFO) is a top-level architecture used by over 300 ontology initiatives in biology, medicine and other fields. When applied to persons, BFO distinguishes three types of attributes: qualities -- such as temperature or height; roles -- such as the patient role; and dispositions -- such as the disposition to go bald or to sweat. Recently it has been proposed that BFO be supplemented with a treatment of a fourth kind of attribute, called 'capability'.
