A Web-based System for Automated Medical Knowledge Acquisition

摘要

Automated knowledge acquisition of production rules can be performed through data mining or direct user input of case-based reasoning. However, knowledge base editors and the decision trees representing case-based reasoning in specific domains are difficult for domain experts to navigate and a domain model that provides a more intuitive interface for knowledge base editing is required. This paper describes the implementation of a hierarchical graphical user interface module that provides an intuitive interface to enter case-based knowledge and automatically generates domain-specific production rules. The knowledge acquisition algorithm and software architecture are described and the code implementation presented. The system environment is addressed for issues in distribution and security control and their solutions are specified. A knowledge acquisition scenario is presented to demonstrate the system operation and evaluated for performance. The GUI deficiencies are identified and conclusions and recommendations for further system improvements are made.
