Summary
A new knowledge acquisition (KA) tool enables pathology experts to formalize descriptive knowledge for computerized diagnostic support. This facilitates better indexing and flexible access to pathology information.
Area of Science:
- Medical Informatics
- Pathology
Background:
- Descriptive pathology knowledge is challenging to utilize for computerized diagnostic support.
- Formalizing this knowledge is key to improving indexing and access.
Purpose of the Study:
- Introduce a knowledge acquisition (KA) tool for experts to formalize pathology knowledge.
- Explore the explicitness and ambiguity of pathology knowledge.
- Investigate expert differences in knowledge formalization and incremental acquisition of decision criteria.
Main Methods:
- Developed a menu-driven knowledge acquisition (KA) tool with incorporated meta-knowledge.
- The tool elicits knowledge by following a pathologist's case description process.
- User interface designed for direct expert input.
Main Results:
- The KA tool facilitates the formalization of descriptive pathology knowledge.
- Meta-knowledge in the tool's structure aids in knowledge elicitation.
- The tool serves as a research instrument for analyzing knowledge explicitness and expert variability.
Conclusions:
- The developed KA tool enables formalization of pathology knowledge for enhanced diagnostic support.
- The tool supports research into the nature of expert knowledge and its formal representation.
- Feasibility of incremental acquisition of decision criteria is being explored.
