2. Course Description

The course begins with a review of the theories underlying biomedical knowledge representation and ontology. The methods and tools for applied ontology as well as the management and maintenance of biomedical ontologies will be discussed in detail, including the principles of ontological realism and the implementation thereof in the Basic Formal Ontology (BFO). Students will gain experience with the Web Ontology Language (OWL) and the limitations thereof, and with utilities to query ontologies expressed in OWL. The students will learn how to use and evaluate classifiers and their role in subsumption. They will learn both the transitive and reflexive closure of subsumption and its applied use in ontology development, maintenance and use. This course also provides an in-depth review of current theories and research underlying the development of biomedical ontologies as well as a comparative critical analysis of the major current biomedical ontologies as well as the methods and tools for biomedical ontology development, use and evaluation.

• Course prerequisites: BMI508 or PHI548 or PHI549.

Course Organization

The course begins with a review of the biomedical/clinical research and information dissemination system that results in the generation of new knowledge and its dissemination into clinical health care practice. This review will also include the current systems and techniques that have been used to model, represent & maintain our biomedical data, information & knowledge for use by clinicians and researchers. The remainder of the course will provide an in-depth review of current theories, methods and tools for the development of ontologies for the organization and management of biomedical data, information & knowledge as well as a critical comparative analysis of the major current biomedical ontologies used in health care and biomedical research settings.
