The article presents a new way to search for and retrieve knowledge in the field of engineering. The researchers created a system that uses a special type of organized information called an ontology to help find relevant information more effectively. By converting keywords into concepts in the ontology and finding similar words, the system can better understand and respond to search queries. This method not only helps find information based on keywords but also allows the system to understand questions and provide answers using fuzzy logic based on the ontology.
