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 course will also provide an in-depth review of current research underlying the development of biomedical ontologies as well as a comparative critical analysis of the major current biomedical ontologies and of the methods and tools used in their application, development and evaluation.
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 and maintain our biomedical data, information and 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 and knowledge as well as a critical comparative analysis of the major current biomedical ontologies used in health care and biomedical research settings.

- Class participants will be divided into groups. The task for each group will be
- 1. to identify some area in which ontology methods can be of value in understanding issues related to patient well-being, along the lines illustrated in the advance readings by Ceusters et al., and Souvignet et al. listed below.
- 2. to propose terms and definitions which need to be added to OGMS to create a corresponding ontology.
- 3. to make the results available electronically by the end of class.
Today is the deadline for submission of 300-400 word abstracts of your term paper. These abstracts will be critically reviewed in the meeting on October 19.
