A fundamental requirement to achieve effectiveness in a medical expert system is the proper representation of knowledge about a patient. Knowledge about a patient is stored in the expert system in terms of clinical records which should contain information about multiple visits of the patient. During each visit, several conversations are made between the patient and the consulting physician. These conversations, being unstructured in nature, cannot be stored in the computer using available structured knowledge representation schemes. So, we propose a recursive frame-based structure for representing clinical records. The frames related to a patient collectively form a frame system, where one frame may point to other frames. The proposed representation scheme is complete, consistent, and free from redundancy. |
