tnm-o

The TNM Ontology

tnm-o is the abbreviation for the TNM Ontology. The TNM Ontology represents the TNM Classification of Malignant Tumours (TNM) in description logic (OWL). For a detailed report on tnm-o see: https://jbiomedsem.biomedcentral.com/articles/10.1186/s13326-016-0106-9.

Objective of this project is to represent the complete TNM Classification system in description logic and provide formal transformation rules between versions. Based on this representation, data on clinical and pathological findings can be classified automatically by documentation systems and (partially) transformed between TNM versions.

tnm-o consists of a stack of hierarchically organized modules:

• BioTop Toplevel Domain Ontology (https://biotopontology.github.io/) defines the foundational classes and relations for tnm-o and thus its underlying ontological framework.
• TNM-O: a hub ontology providing common classes and definitions which are used by all organ-specific modules of tnm-o. TNM-O is the hup in which other modules can be loaded depending on the application context.
• TNM-Anatomy: an ontology providing definitions for common anatomical entities
• Organ specific modules: representations of TNM definitions according to the organ-specific structure of the TNM classification system for different versions
• Transformation rules: organ-specific, formal rules for the transformation between different versions
