Development and Evaluation of an Ontology for Non-Invasive Respiratory Support in Acute Care
Pith reviewed 2026-05-19 03:20 UTC · model grok-4.3
The pith
An ontology unifies concepts for noninvasive respiratory support to aid clinical reasoning in acute care
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
The authors created the NIRS ontology with 145 classes, 11 object properties, 18 data properties, and 949 axioms, plus 392 annotations drawn from controlled vocabularies. They incorporated SWRL rules to support rule-based reasoning and tested the system by adding six patient scenarios, then used SPARQL queries to confirm that the ontology produces correct inferences for therapy recommendations.
What carries the argument
The NIRS ontology built in OWL with SWRL rules, which defines classes and relationships for noninvasive respiratory support modalities and patient conditions to enable logical inferences and SPARQL queries for clinical recommendations.
Load-bearing premise
The six hand-crafted patient scenarios sufficiently test the ontology's handling of real-world clinical variability and the chosen class definitions plus SWRL rules accurately capture current medical practice.
What would settle it
Applying SPARQL queries to the ontology with a larger collection of real patient cases from acute care and finding that the generated therapy recommendations do not align with expert clinician judgments.

Managing patients with respiratory failure increasingly involves noninvasive respiratory support (NIRS) strategies to support respiration, often preventing the need for invasive mechanical ventilation. However, despite the rapidly expanding use of NIRS, there remains a significant challenge to its optimal use across all medical circumstances. It lacks a unified ontological structure, complicating guidance on NIRS modalities across healthcare systems. This study introduced NIRS ontology to support knowledge representation in acute care settings by providing a unified framework that enhances data clarity and interoperability, laying the groundwork for future clinical decision-making. We developed NIRS ontology using the Web Ontology Language (OWL) and Protege to organize clinical concepts and relationships. To enable rule-based clinical reasoning beyond hierarchical structures, we added Semantic Web Rule Language (SWRL) rules. We evaluated logical reasoning by adding a sample of 6 patient scenarios and used SPARQL queries to retrieve and test targeted inferences. The ontology has 145 classes, 11 object properties, and 18 data properties across 949 axioms that establish concept relationships. To standardize clinical concepts, we added 392 annotations, including descriptive definitions based on controlled vocabularies. SPARQL query evaluations across clinical scenarios confirmed the ontology ability to support rule based reasoning and therapy recommendations, providing a foundation for consistent documentation practices, integration into clinical data models, and advanced analysis of NIRS outcomes. In conclusion, we unified NIRS concepts into an ontological framework and demonstrated its applicability through the evaluation of patient scenarios and alignment with standardized vocabularies.

Referee Report
Summary. The manuscript presents the development of an OWL-based NIRS ontology in Protege for organizing clinical concepts in noninvasive respiratory support for acute care. The ontology contains 145 classes, 11 object properties, 18 data properties, and 949 axioms, augmented with SWRL rules for rule-based reasoning. Evaluation consists of applying the ontology to six patient scenarios and using SPARQL queries to retrieve inferences and therapy recommendations, with 392 annotations for standardization against controlled vocabularies.
Significance. If the class definitions and SWRL rules are shown to align with medical consensus and handle diverse presentations, the ontology could provide a reusable framework for consistent NIRS documentation, data interoperability, and future clinical decision support tools in acute respiratory care.
major comments (1)
- [Abstract, evaluation paragraph] Abstract, evaluation paragraph: The central claim that SPARQL queries on the six scenarios confirm the ontology's ability to support rule-based reasoning and therapy recommendations rests on an evaluation that uses only six hand-crafted patient scenarios. No external expert review of the SWRL rules, no direct comparison against published NIRS guidelines, and no testing on real EHR-derived cases or independent literature are reported; this leaves open the possibility that mismatches with actual practice would go undetected.
minor comments (2)
- The manuscript would benefit from an explicit table or appendix listing the SWRL rules and the specific inferences each rule is intended to produce, to allow readers to assess coverage independently of the six scenarios.
- Clarify whether the 949 axioms include the SWRL rules or only the OWL axioms, and provide a breakdown of how many axioms are subclass axioms versus property restrictions.
Simulated Author's Rebuttal
We thank the referee for their detailed and constructive feedback on the evaluation of our NIRS ontology. We have addressed the major comment by revising the manuscript to more accurately reflect the preliminary and illustrative nature of the current evaluation.

Referee: [Abstract, evaluation paragraph] Abstract, evaluation paragraph: The central claim that SPARQL queries on the six scenarios confirm the ontology's ability to support rule-based reasoning and therapy recommendations rests on an evaluation that uses only six hand-crafted patient scenarios. No external expert review of the SWRL rules, no direct comparison against published NIRS guidelines, and no testing on real EHR-derived cases or independent literature are reported; this leaves open the possibility that mismatches with actual practice would go undetected.
Authors: We agree that the evaluation is limited to six hand-crafted scenarios and does not include external expert review, direct guideline comparisons, or real EHR-derived cases. These scenarios were developed to represent diverse acute care presentations and to demonstrate the practical application of the SWRL rules and SPARQL queries for rule-based reasoning. The manuscript's focus was on ontology development and initial functionality testing rather than comprehensive clinical validation. In the revised version, we will modify the abstract to change 'confirmed' to 'demonstrated' and will add an explicit limitations subsection in the discussion that acknowledges the preliminary scope, the absence of external validation, and the need for future work involving expert review, published NIRS guidelines, and real-world EHR testing. These textual revisions will qualify our claims appropriately while preserving the contribution of the ontology framework and its annotations to controlled vocabularies. revision: partial
Circularity Check
No circularity: constructive ontology development with explicit construction and consistency checks
full rationale
The paper constructs an OWL ontology (145 classes, 11 object properties, 18 data properties, 949 axioms, 392 annotations) plus SWRL rules from clinical concepts drawn from controlled vocabularies, then evaluates inferences via SPARQL on six hand-crafted scenarios. No equations, fitted parameters, predictions, or self-citations appear in the derivation chain. The central claim—that the ontology supports rule-based reasoning—is demonstrated by direct construction and query results rather than reducing to its own inputs by definition or statistical forcing. This is a standard knowledge-representation workflow whose validity rests on external medical consensus and future validation, not internal circularity.

- The paper's claim conflicts with a theorem or certificate in the canon.
- unclear
- Pith found a possible connection, but the passage is too broad, indirect, or ambiguous to say the theorem truly supports the claim.
