This study presents a methodology for constructing a Traditional Chinese Medicine (TCM) semantic network system based on SNOMED CT, addressing challenges in terminology standardization and knowledge integration within the TCM domain. By analyzing SNOMED CT's framework and encoding rules, and incorporating TCM-specific features (e.g., property-channel tropism, efficacy classification), we designed an ontological model encompassing core concepts, attribute relationships, and terminology mapping. The system employs semantic web technologies (e.g., RDF, OWL) to establish hierarchical and associative relationships among TCM concepts (e.g., "incompatibility," "pharmacological effects") while ensuring compatibility with SNOMED CT for international standardization. Experimental validation involved constructing a prototype semantic network (e.g., nodes for Astragalus membranaceus) to demonstrate the system's efficacy in terminology normalization, knowledge reasoning, and cross-domain data linkage. This research provides a feasible solution for standardizing and enabling intelligent applications (e.g., clinical decision support, big data analytics) of TCM knowledge, while expanding SNOMED CT's applicability to traditional medicine. It aims to foster integration between TCM and Western medicine and advance the modernization and digitization of TCM through foundational semantic infrastructure.
Description
The study focuses on:
Terminology Standardization: Developing a TCM-compatible terminology system based on SNOMED CT to unify TCM expressions.
Semantic Network Construction: Using RDF/OWL to model TCM concept relationships (e.g., property-channel tropism, efficacy, incompatibility).
Knowledge Integration & Mapping: Aligning TCM knowledge (e.g., herbs, formulas, pharmacology) with SNOMED CT for interoperability.
Application Validation: Testing feasibility via exemplary networks (e.g., Pogostemon cablin nodes) for clinical decision support and analytics.
Scope
Global Authority: Widely adopted in EHRs, enhancing TCM's international compatibility.
Structured Knowledge Representation: Hierarchies and semantic relationships support modeling TCM complexities.
Semantic Reasoning: Enables future applications like automated drug interaction checks.
Cross-Domain Mapping: Bridges TCM-Western medicine terminology (e.g., herb-drug combinations).
Extensibility: Open update mechanisms allow incremental TCM concept additions.
How SNOMED CT will be used
Key uses include:
Standardization Framework: Adapting SNOMED CT's hierarchies (e.g., "substance/drug," "procedure") for TCM ontology design.
Semantic Extension: Extending SNOMED CT's relationships (e.g., Is_a, Part_of) to TCM-specific links (e.g., "channel tropism").
Terminology Mapping: Partial alignment of TCM concepts (e.g., Astragalus "Herbal drug") for cross-domain interoperability.
Technical Compatibility: Using OWL/RDF to ensure integration with global medical knowledge graphs.
Limitation: SNOMED CT's limited TCM coverage necessitates supplemental TCM-specific concepts.
