LLMs in Ontology Engineering
Recent research highlights the growing role of Large Language Models (LLMs) in supporting ontology-related tasks, including learning, mapping, enrichment, and knowledge extraction. Early transformer-based architectures like BERT were foundational, extracting structured knowledge from text. More advanced LLMs, such as GPT-3 and PaLM, have demonstrated capabilities in generating concept hierarchies, translating natural language into ontology axioms, and enhancing knowledge base construction through prompt ensembles. However, the structured integration of human expertise across varying degrees of involvement remains an underexplored area, which this study aims to address.
Our Collaborative Approach
This study employed a four-phase experimental methodology to assess LLM capabilities in generating and refining Parkinson's Disease (PD) ontologies. We evaluated multiple LLMs (ChatGPT-3.5, ChatGPT-4, Gemini/Bard, Claude, Llama2) across different prompting strategies and collaborative frameworks, comparing generated ontologies against the Wear4PDmove gold standard using structural metrics (classes, object properties) and expert review.

Experiment 1 assessed autonomous generation using One-shot (OS) and Decomposed Sequential Prompting (DSP). Experiment 2 introduced X-HCOME, integrating human and LLM tasks. Experiment 3 involved expert review of X-HCOME's false positives. Experiment 4 (SimX-HCOME+) simulated iterative collaboration, including natural language-to-SWRL rule transformation.
Key Findings on LLM Performance
LLMs demonstrated the ability to generate syntactically valid and semantically meaningful ontologies autonomously (OS/DSP), but with limited conceptual coverage. Structured human-LLM collaboration through X-HCOME significantly improved ontology completeness and evaluation metrics.

|---|---|---|
| Autonomous (OS/DSP) |
|
~10-20% |
| Collaborative (X-HCOME) |

Expert review of X-HCOME outputs was crucial, reclassifying many initial "false positives" as clinically relevant knowledge extensions. This demonstrated that LLMs, when guided by experts, can contribute to ontology evolution beyond merely replicating existing models.

The Spectrum of Human-LLM Collaboration
The study clearly indicates a positive correlation between increased human involvement and improved ontology quality. LLMs function most effectively as collaborative assistants rather than standalone engineers, especially in complex domains like Parkinson's Disease monitoring.
Structured human-LLM collaboration, from defining scope and requirements to validating concepts and refining outputs, proved essential for achieving higher conceptual coverage and clinical relevance. This hybrid approach leverages LLMs for initial generation and automation, while human experts provide critical oversight and domain-specific knowledge.
Challenges and Future Directions
Despite significant progress, several limitations were identified. LLMs struggled consistently with modeling relational structures (object properties), with F1 scores remaining low (0-12% before expert review). Natural language to SWRL rule transformation also proved challenging, generating syntactically valid but logically incomplete expressions.
Key Takeaway: The Relational Modeling Gap
Challenge: LLMs consistently showed low performance (0-12% F1 scores across methodologies) in generating object properties, indicating a fundamental weakness in modeling relational structures. Even with collaboration, this area remains a significant bottleneck.
Impact: Accurate relational modeling is crucial for the richness and inferential power of ontologies in clinical decision support systems. This gap limits LLMs' autonomous capability to build complete, functional knowledge graphs without extensive human intervention for property definition and constraint enforcement.
Recommendation: Future research should focus on prompt engineering and fine-tuning strategies specifically designed to improve LLMs' understanding and generation of complex relational axioms and domain-range constraints. Specialized LLM configurations tailored for ontology engineering tasks may also be beneficial.
The reliance on a single gold-standard ontology also presented a challenge, as LLM-generated valid knowledge extensions were initially penalized as false positives. This highlights the need for more flexible evaluation methods that account for knowledge discovery. Future work will explore applying these methodologies to other healthcare domains and developing specialized LLMs for ontology engineering tasks.
