Specific Domain Ontology Construction Using Large Language Models

arXiv:2606.20691v1 Announce Type: cross Abstract: Ontologies are useful structures to organize and maintain information that can be understood both by humans and systems. However, since their manual crafting is a laborious task, many specific domains lack reference ontologies. The outstanding ability for understanding natural language demonstrated by the Large Language Models (LLMs) has motivated their application to aid on a variety of fields, including on ontology development. This work presents the experimentation with a technique that uses LLMs in the role of domain experts to build concep

Why this matters
Why now

The rapid advancements and widespread adoption of Large Language Models (LLMs) make their application to complex tasks like ontology construction a natural and timely next step, addressing existing bottlenecks in knowledge organization.

Why it’s important

Automating specific domain ontology construction using LLMs significantly reduces the manual effort and expertise required, accelerating knowledge representation and enabling more sophisticated AI applications across specialized fields.

What changes

The barrier to creating and maintaining detailed, machine-readable knowledge structures for niche domains is lowered, potentially democratizing access to structured information and improving AI system performance.
