    Summary

    This study introduces a computer-based medical terminology with 140,000 terms, organized hierarchically by meaning. This semantic address system aims for global compatibility in medical coding.

    Area of Science:

    • Medical Informatics
    • Computational Linguistics
    • Knowledge Representation

    Background:

    • Current medical terminologies lack a unified, meaning-based organizational structure.
    • Efficient coding and retrieval of medical information are crucial for healthcare.
    • Existing systems may present challenges in achieving global compatibility.

    Purpose of the Study:

    • To present a novel computer-based medical terminology.
    • To describe a unique systematization of terms based on semantic similarity.
    • To propose a standardized coding method using semantic addresses for global use.

    Main Methods:

    • Construction of a large-scale (140,000 terms) medical terminology.
    • Systematization of terms into a single hierarchical tree using semantic similarity as the key attribute.
    • Development of a term typing system based on knowledge patterns and relationships (arcs) between terms (nodes).
    • Definition of a 'semantic address' based on a term's position within the hierarchy for coding.

    Main Results:

    • A hierarchical medical terminology of approximately 140,000 terms was created.
    • The systematization resulted in a single, unified hierarchical tree structure.
    • Six distinct types of medical terms were identified based on their knowledge patterns.
    • A coding system, the 'semantic address', was derived from the hierarchical position.

    Conclusions:

    • The developed computer-based medical terminology offers a structured, meaning-based approach.
    • The semantic address system provides a novel method for medical term coding.
    • The semantic address is recommended for achieving worldwide compatibility in medical terminology and coding.
