  We tackle the task of enriching ontologies by automatically translating
natural language sentences into Description Logic. Since Large Language Models
(LLMs) are the best tools for translations, we fine-tuned a GPT-3 model to
convert Natural Language sentences into OWL Functional Syntax. We employ
objective and concise examples to fine-tune the model regarding: instances,
class subsumption, domain and range of relations, object properties
relationships, disjoint classes, complements, cardinality restrictions. The
resulted axioms are used to enrich an ontology, in a human supervised manner.
The developed tool is publicly provided as a Protge plugin.
