Development of a Knowledge-based Application Utilizing Ontologies for the Continuing Site-specific JJ1017 Master...

Area of Science:

• Medical Informatics
• Radiology
• Knowledge Engineering

Background:

• Medical information systems are increasingly adopted in Japanese healthcare facilities.
• Standardized radiologic procedure masters are crucial for data consistency and interoperability.
• The JJ1017 guideline defines a standard for these radiologic procedure masters.

Purpose of the Study:

• To develop the JJ1017 Knowledge-based Application (JKA).
• To support the ongoing maintenance of site-specific JJ1017 masters.
• To enhance the usability of medical information systems for medical technologists.

Main Methods:

• Construction of the JJ1017 Ontology (JJOnt) using the Hozo environment.
• Development of essential modules (operation, I/O, graph) for master maintenance.
• Unit testing of the integrated JKA system.

Main Results:

• The JJ1017 Ontology (JJOnt) comprises 21,697 classes.
• External beam radiotherapy codes represent the largest category (51%) within radiologic procedures.
• Unit testing confirmed the functionality of key operations like keyword search and class editing.

Conclusions:

• The JJOnt serves as a robust knowledge base for medical information systems.
• The JKA is designed to facilitate the maintenance and enhancement of JJ1017 masters.
• The application aims to improve semantic accuracy in information exchange for medical technologists.
